I come across a lot of items, such as the Kepler Planet Items and deide that they could each be described as an "extrasolar planet". However, there are like 200, maybe even 300 items for this, and it gets annoying. Is there like an equivalent of AutoWikiBrowser that will automaticaaly allow me to put the description "extrasolar planet" onto the item?  – The preceding unsigned comment was added by PokestarFan (talk • contribs) at 21:51, 28 February 2017‎ (UTC).

Quickstatements. You have to create a list of entries like 'QXXX TAB Den TAB "extrasolar planet"'. --Emijrp (talk) 22:01, 28 February 2017 (UTC)

@Emijrp This works, but I wonder if you know any other variants that can use a keyword to do it, because I typed in a huge range and it messed up some other items. PokestarFan (talk) 23:33, 28 February 2017 (UTC)

@PokestarFan: I see you're cleaning up your mess - I fixed one for you. You need to first get a reliable collection of QXXX's, you can't just assume that some range is what you're looking for. Start with the Query Service (link in the left navbar here) if you know at least something about the properties of the items you are looking for. ArthurPSmith (talk) 14:55, 1 March 2017 (UTC)

@ArthurPSmith: Thanks for the advice. I just queued around 1500 items.

How can I define (by specifying a set of languages) which labels and aliases are searched when typing in the search field or a field that expects an item or property? I would specifically like to specify a set of more than one language (though I wouldn’t mind if the user-interface language were necessarily included in the set of searched languages). Thanks, BlaueBlüte (talk) 22:20, 28 February 2017 (UTC)

I don't think that's currently possible. I agree that it would be a nice feature. I personally sometimes want to search in German and sometimes in English and it would be nice if I could enter both. ChristianKl (talk) 09:36, 1 March 2017 (UTC)

Why does ICAO airport code (P239) have datatype "String" but ICAO airline designator (P230) datatype "external identifier"? Surely they should be the same? Can we harmonize them without breaking things? Deryck Chan (talk) 14:54, 1 March 2017 (UTC)

they appear to be both "String" type - are you looking at something different? The discussion of why they didn't qualify as external id's is here. ArthurPSmith (talk) 15:07, 1 March 2017 (UTC)

My apologies. I mean why callsign of airline (P432) is "external identifier" but the two ICAO (and IATA as well) identifiers above aren't. I'm not sure why it needs to "resolve" to anything and be unique - IATA and ICAO codes move with airlines and airports as one gets succeeded by another in a continuous chain of succession. Deryck Chan (talk) 17:43, 1 March 2017 (UTC)

About 1½ months ago, Yash nagar mass-imported defining formula (P2534) statements from Wikipedia. Objections arose; many of the statements are incorrect, and in the end the user themselves agreed that the statements should be mass-reverted. Can someone please do that? Otherwise, I fear those incorrect statements will remain in Wikidata for a long time. (For example, I removed one just now where the formula only appeared in a reference at the end of the linked Wikipedia article.)

Pinging participants of the discussion on the user talk page: ArthurPSmith, Fnielsen, Vlsergey, Airon90, Infovarius. —Galaktos (talk) 14:27, 26 February 2017 (UTC)

@Galaktos: - Do we have a count of how many were imported? defining formula (P2534) has only been used 3,470 times so this wasn't a huge mass update (unless it's been fixed already?) A short list of ones still to fix is on the constraints page: Wikidata:Database reports/Constraint violations/P2534 so I think it might be better to clean up by hand rather than mass revert here. But if a mass revert is done (if it hasn't already been done) I'm ok with that too. ArthurPSmith (talk) 20:26, 27 February 2017 (UTC)

@ArthurPSmith: well, if a couple thousand statements aren’t “huge” or “mass”, then I just wasn’t aware of the usual scale those terms imply on Wikidata :) I think that was about the extent of statements that was added. But I do think a full revert of those statements (the ones added by Yash nagar via quickstatements – not all statements, if possible!) is in order, because many of the incorrect statements won’t show up on any constraints pages since they’re only logically wrong, not syntactically (example). Afterwards, the statements could be imported into the Primary Sources tool again, so that human editors can verify their correctness before adding them. —Galaktos (talk) 00:28, 28 February 2017 (UTC)

Some were fixed (about hundred by me, e.g.). I suppose that they should be removed from "Primary Sources" suggestions in order to not be added again. --Infovarius (talk) 20:59, 28 February 2017 (UTC)

No, the point of Primary Sources is that the statements are verified by a human before being added, which is exactly what’s needed here! Yash nagar just decided to sidestep this quality control. —Galaktos (talk) 19:30, 1 March 2017 (UTC)

There is a lot of item that have P31=software or sublass AND P31=free software AND copyright license (P275)=freesoftware license or subclass. I think that P31=free software must be deleted because we have a specific property for the license. Some opinion? We can delete it?

SELECT ?item WHERE {
  ?item wdt:P31/wdt:P279* wd:Q7397. #subclass of software
  ?item wdt:P31 wd:Q341. #free software
  ?item wdt:P275/wdt:P279* wd:Q3943414. #subclass of free software license
}

--ValterVB (talk) 17:01, 28 February 2017 (UTC)

Hi ValterVB, I tend to agree with you reasoning. There is some case where the licence of a software change (from non-free to free for instance) and it is much more simple to put the information only in copyright license (P275) and not duplicate it in instance of (P31).

Where do I localize the date and time formatting in the "point in time" datatype? Ideally I want to make one set of changes which will make both the Wikidata web interface and Wikidata calls from other Wikimedia projects in that language default to the same format. At the moment the formatting of dates in Cantonese is atrocious. Deryck Chan (talk) 11:25, 1 March 2017 (UTC)

Curlie ID (P998) refers to a dmoz ID but as announced today, DMOZ will be going offline in two weeks. The community there will fork but I'm not sure if 1.) we want to follow them with this property and 2.) if it's worth retaining DMOZ ids for historical purposes but removing the link functionality as the links will go down at the original source (although, again, they will be resurrected somewhere else). Thoughts? —Justin (koavf)❤T☮C☺M☯ 01:05, 2 March 2017 (UTC)

There are lots of ID properties whose corresponding databases have not been updated in decades (as with NSDAP membership number (1925–1945) (P2298)) and yet we do not consider deleting them. dmoz should not be an exception to this trend, especially if adjusting links is a simple matter of changing formatter URL (P1630) to third-party formatter URL (P3303) on the property itself. Mahir256 (talk) 01:20, 2 March 2017 (UTC)

The Freebase-ID is a better example. About DMOZ: Maybe we could get a new property for the new DMOZ? Isn´t wikivoyage using dmoz quite a lot? But I do not know if they use Wikidata for those dmoz links. --Molarus 02:07, 2 March 2017 (UTC)

That depends whether the "new DMOZ" uses the same IDs as "old DMOZ". Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 15:43, 2 March 2017 (UTC)

I am writing from the National Library Board Singapore. We are currently maintaining a list of name authorities of Singapore entities (eg. people, organisations and places) in our own Knowledge Organisation System (KOS). Each name authority record contains attributes with information on the entity described, such as scope note, birth and death date, as well as variations of the preferred name in the official languages of English, Chinese, Malay and Tamil. The name authority record is represented by an unique URI to facilitate the exposure of our records in the linked data environment. We would like to find out:

• How do we expose our record data through Wikidata to facilitate the development of linked data? Is it possible to provide only our name authority records URI and insert into the existing entities in Wikidata that match with our name authorities?
• What is the process involved in contributing our record data to Wikidata?

 – The preceding unsigned comment was added by Nlbkos (talk • contribs) at 03:20, 2 March 2017‎ (UTC).

How wonderful that you consider both to connect your data to ours and are interested in sharing data as well. In my opinion there are several things we would like to consider

• Linking; when you have an ID for the items in your database, we can include this in Wikidata. When people click on it they will go to your KOS.
• Labels; it will be wonderful to ensure that we have labels in English, Chinese, Malay and Tamil. Importing them from your sources where we have none seems uncontroversial to me.
• Data; there are three aspects
  • No data at Wikidata - after some discussion you may use a bot to import data to Wikidata where we have no data (for existing items)
  • Same data at Wikidata - it would be cool to use you as a reference so that we use your data as a source and are more confident that this data is indeed correct.
  • Differing data at Wikidata - This is where either our data or your data is problematic. We do not have a proper workflow for this. It would be cool to work one out.

Thanks, GerardM (talk) 06:46, 2 March 2017 (UTC)

As a practicality, something that would be useful to know is how co-referenced to other authorities your data already is -- eg VIAF, or other library systems. If you already have significant co-referencing this can greatly speed up the matching process. Jheald (talk) 09:23, 2 March 2017 (UTC)

@Nlbkos: Further to the above, it would be helpful if you could provide some sample URIs, so we can see how they, and your data, are structured. If you issue an identifier for each subject, we can create a property for it, like we have, for example, with GRID ID (P2427). I am happy to help you with the process of making a formal proposal for a property. Then, if you wish, you can provide us with a data file with those IDs (or URIs for them), and the other data fields you mention, and we can use our automated tools to either import your IDs correctly, or to provide a list for manual checking and addition.

How to get the dates of the creation and last modification of an entity and its properties using Lua? Thanks for you answer. --RolandUnger (talk) 07:33, 2 March 2017 (UTC)

Reading this documentation makes me sure this is impossible. However, you could get the date of last modification of an entity with frame:preprocess( '{{REVISIONTIMESTAMP:Q123}}' ) where Q123 can be replaced with the appropriate id but this will only work on Wikidata, not any another wiki.

No. But you can create lists of items without descriptions by using PetScan and add the descriptions using QuickStatements. Stryn (talk) 20:18, 28 February 2017 (UTC)

Hi, I found Q716489, the item for the proposed Republic of Taiwan, which doesn't have a P31 statement. I entered the Q1145276 item, fictional country, but I think that applies to countries in works of fiction, rather than a proposed government. Is there a better item for the P31 property?

state with limited recognition (Q15634554) perhaps? K7L (talk) 14:34, 1 March 2017 (UTC)

It's not a great solution - state with limited recognition (Q15634554) implies it did exist in some form but wasn't accepted by the world, while in this case it never existed at all. Some similar cases, all entirely proposals with nothing on the ground:

• States or provinces - Princeland (Q7244416) & Auralia (Q4822094) (Australia); Maritime Union (Q6765853), Proposal for the Province of Montreal (Q7250370), Proposal for the Province of Toronto (Q7250371), Province of Buffalo (Q7252558) (Canada); Westsylvania (Q537786), Superior (Q3591842), Absaroka (Q4669674), Lincoln (Q3109787), Jefferson (Q6175355), Jefferson (Q1686385), Lincoln (proposed Northwestern state) (Q8842957). Cascadia (Q1128483) (USA); Bodoland (Q2577663), Mithila (Q1076032), Kosal state movement (Q6432969), Harit Pradesh (Q11925241), Gorkhaland (Q260713), & maybe Mangalorean regionalism (Q6748735) (India)
• Countries - Antillean Confederation (Q4774888), Basque Republic (Q4867855), Balkania (Q1566489), Proposed Bosniak republic (Q24915851), Central Confederacy (Q5060630), Dravida Nadu (Q600776), East African Federation (Q976091), Éire Nua (Q8078182), Federal Republic of China (Q17002762), Federal Republic of Mindanao (Q17069572), Fertile Crescent Plan (Q5445575), Imperial Federation (Q3149417), North American Union (Q1164609), and many others (see all the bits of Category:Proposed countries (Q8797905))

None of these has a great P31, and most have none at all, except possibly Gorkhaland (Q260713) which is down as P31:proposed states and union territories of India (Q4808085). I wonder if this is the best way to go - create a "proposed country" item as a subclass of country & proposal, and work from there. Andrew Gray (talk) 20:41, 1 March 2017 (UTC)

@Andrew Gray: Or instance of (P31)micronation (Q188443), as there's already a Taiwanese example Taiwan Civil Government (Q17023229) existing? --Liuxinyu970226 (talk) 10:56, 2 March 2017 (UTC)

A micronation is a different thing - "an entity that claims to be an independent nation or state but is not recognized by world governments or major international organizations". So a small-scale case of state with limited recognition (Q15634554). Andrew Gray (talk) 12:18, 2 March 2017 (UTC)

Öland Municipality (Q10727246) was a proposed Swedish municipality. It was voted down in a local referendum in 2009. -- Innocent bystander (talk) 13:07, 2 March 2017 (UTC)

I think that's the best approach - and here you go :-). proposed country (Q28864179), and the broader proposed administrative territorial entity (Q28864185) Andrew Gray (talk) 22:23, 2 March 2017 (UTC)

However, it is not a good idea to import values from {{jmdb name}} from jawiki en masse without checking first and understand Japanese, some of them are not about the subject of the article (example). --Thibaut120094 (talk) 13:54, 27 February 2017 (UTC)

http://www.jmdb.ne.jp/person/p0410410.htm is a JMDB item which is not a person, but rather a department of a company. Syced (talk) 13:52, 27 February 2017 (UTC)

I imported 1.7K values. We have 12 constraint violations, most apparently due to the constraint being too tight. I don't think that's unreasonable. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:55, 27 February 2017 (UTC)

If some aren't about the subject of the article that seems like a bad idea. ChristianKl (talk) 10:12, 28 February 2017 (UTC)

"If". Do you have any evidence of this happening, and can you quantify the problem? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:17, 28 February 2017 (UTC)

@Thibaut120094: said that it's true for some of them and pointed out an example. ChristianKl (talk) 13:54, 28 February 2017 (UTC)

Indeed, but I asked for evidence and quantification, not anecdote. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 14:13, 28 February 2017 (UTC)

The fact that there's an example shows evidence. As far as quantification goes, I don't speak Japanese, so I can't help you there, but the person who does speak Japanese appearently thinks that there are enough items for which the import creates wrong data. In a case like this I don't think it's a good idea to import the data without being able to read the content. ChristianKl (talk) 09:46, 1 March 2017 (UTC)

The claim for which I asked for evidence was "some", not "a". Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 17:10, 2 March 2017 (UTC)

Andy Mabbett:If you create me a wiki page containing the list of 1700 Japanese labels, I can quickly delete everything that does not sound like a person name from that list. Cheers! Syced (talk) 03:22, 3 March 2017 (UTC)

I will soon do a bulk upload of doctoral thesis (Q187685) data from the University of Oxford. One thing I'm not sure is how to indicate the relationship between the thesis and the host institution. None of the doctoral theses presently have this property. For example, Ronald Hutton (Q3087695) got a Doctor of Philosophy (Q752297) by submitting a doctoral thesis (Q187685) to University of Oxford (Q34433). What property can I put in the record about the thesis to indicate its connection to University of Oxford (Q34433)? I'm not happy with publisher (P123) because the university might not publish the thesis: they might just keep a copy in their library. Not all theses are published, and the publication and inception of a thesis are separate events. conferred by (P1027) does not seem appropriate because the institution confers the degree, not the thesis. affiliation (P1416) is a property of a person rather than a creative work. So I'm not sure if there's an existing property that suits, or a new property needs creating. Any suggestions welcome. MartinPoulter (talk) 16:14, 2 March 2017 (UTC)

Here's a query for all the properties currently used on thesis (Q1266946) tinyurl.com/hp6abtl, with example values.

It looks like publisher (P123) has been used 25 times; though the question is, as you point out, how seriously use of that property should be taken as an indication that the work has actually been "published" -- i.e. made available, so that anyone sufficiently motivated can secure a copy. (I'm not sure whether placing a work where it is openly available for photocopy counts as "publication"; it might, in a narrow legal copyright sense; but perhaps not in the more everyday use of the word).

The only other property that looks to have been used much is sponsor (P859) -- but I presume that means who paid for the work.

There's a handful of educated at (P69) but that certainly looks wrong. Jheald (talk) 17:52, 2 March 2017 (UTC)

I took a look at some examples where we have an OCLC number for the work, tinyurl.com/zs85w5n.

It looks as if WorldCat has a separate field for this, "Dissertation:" -- see eg [1], [2]; although for some entries the import of metadata seems to have gone a bit out of sync for some fields, eg: [3], [4].

So a specific new property "Dissertation for" might be a good idea. This allows a publisher to be recorded separately, if the dissertation was then published in book form. Jheald (talk) 18:13, 2 March 2017 (UTC)

I'd use affiliation (P1416), which can be repurposed if required. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:32, 2 March 2017 (UTC)

I was tempted by Andy's suggestion but I've decided to import thesis data now, and add institutional data when the property exists for it. So I've proposed a "dissertation for" property since Jheald makes a very good case. Cheers, MartinPoulter (talk) 11:08, 3 March 2017 (UTC)

A help page says:

• The best way to see if Wikidata already has a page on the item you wish to add is to use the item by title search. A link to this search is on the sidebar navigation menu on the left of the screen. By default, it is the fifth link from the top, and is entitled "Item by title".

What's the purpose of this advice? Why is that search better than the default search on the right side of the screen? ChristianKl (talk) 08:33, 3 March 2017 (UTC)

@ChristianKl: I honestly do not know.

This is interesting, and something we could emulate, given the amount of artworks on Wikidata and Commons:

-- Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:34, 3 March 2017 (UTC)

I have a long-standing request at Wikidata:Bot requests#‎Taxon labels for a bot to add scientific names of taxons as labels. user:Succu has objected to this, while recently, his bot is doing exactly that. When I pointed out this apparent ambiguity, he claimed that it is "is adding labels in a few languages where there is agreement to do so" (my emboldening).

I have now asked him three times for details of such agreement(s), but I have yet to receive a straight answer (he tells me "Simply follow the discussions", "I did often enough. So it's meanwhile a little bit boring", and "Again: follow the links in this thread. There is no need to repeat it again and again.").

Does anyone know whether these agreements exist, who made them, what was actually agreed to, and where they are recorded?

Aside from this, it seems ludicrous to be using a bot to add a label like "Drusus sharrensis" to the relevant item in languages like Bulgarian, Latin, and Russian, while at the same time objecting to anyone else doing so in in, say, Catalan, Dutch, English, German, French, Italian, Spanish, or other western-alphabet languages. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:26, 23 February 2017 (UTC)

This is discussed for the 5th (?) time now... --Succu (talk) 16:33, 23 February 2017 (UTC)

That is neither an answer, nor a discussion Succu. I find that it is a reasonable question to be asked, reasonable to have a clear explanation and this is a reasonable place for a discussion if one believes that one is being fobbed off, or non-answered. [Such declinations border on passive-aggressive behaviour.] So to help us all out, please can we have a clear and concise instruction on the addition of scientific names as labels in all the languages. I see it is happening for 80+ languages for family name, so it seems reasonable that it happens for taxonomic names. Thanks.  — billinghurst sDrewth 01:33, 24 February 2017 (UTC)

I am not aware of any discussions on the subject, so for the that is the 1st one. So it seems to me that both Andy Mabbett and Succu agree that such edits are needed, I agree as well. So what is the issue? That Succu changed his mind without admitting it and now does not want to talk about it? As for adding scientific names to Cyrillic alphabet wikis: that seems to be correct if I do to ru:Оконные_мухи the scientific name uses Latin alphabet. --Jarekt (talk) 02:36, 24 February 2017 (UTC)

Agree with Jarekt, billinghurst and Andy. Very sensible to add Latin scientific names of taxons as labels to cover all languages; long past time that we stop tolerating deliberately unhelpful snark and call it out for what it is - a form of bullying. --Tagishsimon (talk) 11:11, 24 February 2017 (UTC)

ludicrous, fobbed of, passive-aggressive behaviour and bullying - Interesting „discussion“.

@Jarekt: The current agreement is Wikidata:Requests for comment/Automatic labelling. --Succu (talk) 11:20, 24 February 2017 (UTC)

Yup, ludicrous, fobbed of, passive-aggressive behaviour and bullying seems to be the consensus. Had you posted the link instead of the snark, we would not be having this side-discussion. Please learn from it. --Tagishsimon (talk) 11:36, 24 February 2017 (UTC)

I read the RfC as being generally supportive. Can you point us at any objections to the proposal? --Tagishsimon (talk) 11:39, 24 February 2017 (UTC)

?!? Wikidata:Bot requests#‎Taxon labels. --Succu (talk) 11:41, 24 February 2017 (UTC)

That RfC was mentioned in the bot-request discussion only in response to my question "Can you show a policy requiring us to obtain consensus from external [WMF] projects before editing here?" (after Succu asked if I had "reached an agreement with svwiwki, cebwiki, warwiki, viwiki or nlwiki" to make the proposed edits in Wikidata). My response then - that's 28 March 2016 - was "Nothing in that May 2013 RfC stops this proposal from continuing; and no policy was created by it", to which Succu did not reply further. Even if that historic RfC were still - or ever - relevant, it shows no consensus either way regarding taxon labels in Russian; and Bulgarian and Latin labels are not mentioned at all. Indeed, the only consensus for oppose was a single voice asking for a temporary hiatus on doing so for Swedish, until other editors were consulted. Succu's reliance on the RfC is bogus. He has been stonewalling the request for a bot for almost a year. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:48, 24 February 2017 (UTC)

At earlier discussions that RfC was accepted as a starting point. Meanwhile some bot owners added labels in selected languages, e. g. User:BotNinja for bg and ru. I simply added this task to my weekly bot run. Have a look at this discussion started on 18 November 2015 where more concerns are expressed. Your recent conclusion from a diff It appears that Succu now agrees that adding scientific names of taxons as labels is a good thing. is not correct. I never agreed that mass adding labels the way you proposed is a good thing. The wording of some users here is not acceptable, especially the one that insinuates a personality disorder (passive–aggressive behavior (Q1153809)). --Succu (talk) 18:57, 24 February 2017 (UTC)

Succu claimed "agreement" for adding labels in languages such as ru, bg & la. He refused my requests to cite such agreement, until in this discussion he cited them to an RfC where no such agreements exist. He now refers to "earlier discussions". Which ones? As for "Passive-aggressive behavior", it may be defined as "the indirect expression of hostility, such as through procrastination, stubbornness, sullen behavior, or deliberate or repeated failure to accomplish requested tasks for which one is (often explicitly) responsible". Others may judge the applicability of that, but it is distinct from "passive-aggressive personality disorder". By all means, though, Succu may take that matter to the administrator's noticeboard. But he should beware of boomerangs. To reiterate, the position of using a bot to add a label like "Drusus sharrensis" to the relevant item in languages like Bulgarian, Latin, and Russian, while at the same time objecting to anyone else doing so in in, say, Catalan, Dutch, English, German, French, Italian, Spanish, or other western-alphabet languages is ludicrous. It is also utterly untenable; and I note that Succu has made no plausible attempt to defend doing so. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 19:39, 24 February 2017 (UTC)

Hmm, one snippet of my statement has been taken out of context on how it was meant from local conversational English. Can we stop chewing on that bone? [If that could be easily excised from this conversation to bring it back to focus, I would do that.] I have apologised to Succu separately for how my comment was perceived. I am not about trying to win an argument with hostility or bullying behaviour.

I would like to see clear statements on what can be done, there is none as far as I can see, and it may be that it doesn't come from Andy or Succu, as this should be an agreed community position.  — billinghurst sDrewth 04:36, 26 February 2017 (UTC)

Succu has now given a substantially different, vague, and conflicting justification for his claim of "agreement", on the Bot Request page, and has indicated there that he is "not not willingly to answer in a thread full of insults" (presumably meaning this one). Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:51, 24 February 2017 (UTC)

In the light of comments made here I propose shortly to get a bot, for items where instance of (P31)=taxon (Q16521), and where there is already a label one one or more languages, which is the same as the value of taxon name (P225), to copy the value of P225 to the label for the following languages:

en,de,fr,it,es,af,an,ast,bar,br,ca,co,cs,cy,da,de,eo,et,eu,fi,frp,fur,ga,gd,gl,gsw,hr,hu,ia,id,ie,is,io,kg,lb,li,lij,mg,min,ms,nap,nb,nds,nds-nl,nl,nn,nrm,oc,pcd,pl,pms,pt,pt-br,rm,ro,sc,scn,sco,sk,sl,sr-el,sv,sw,vec,vi,vls,vo,wa,wo,zu

(all of which use the western alphabet) where no label already exits in that language.

Thoughts on doing this for items without a label in any language?

@billinghurst, Jarekt, Tagishsimon: FYI. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:38, 28 February 2017 (UTC)

I don't enter bot requests particulars. I am more interested in setting clarity for where we add all labels per language, so it is broader than taxonomic. Where is that decision made, who makes the decision, how and where is that recorded. As I say on a reasonably regular basis, find that information so that one can follow the "rules" is hard.  — billinghurst sDrewth 22:05, 28 February 2017 (UTC)

It does seem unfortunate to be spamming so many languages with so much duplicate material.

Tracked in Phabricator
Task T154260

Tracked in Phabricator
Task T89213

There are a couple of tickets open -- one for WDQS, one for Wikidata iteself -- that consider adding identifying a "fallback default" label, to be available to be shown if no other was available. Similarly one might consider adding "language-independent" / "native language" as additional pseudo-languages for labels, that perhaps could always be shown in addition to the labels in the user's own preferred languages.

But I see the second bug has made no progress in 18 months, so maybe it is necessary to spam all the languages. Jheald (talk) 22:12, 28 February 2017 (UTC)

Whether you agree with it or not, please don't refer to good faith editing as "spamming". Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:16, 28 February 2017 (UTC)

No offence was intended. I am sorry if any was caused. Jheald (talk) 22:26, 28 February 2017 (UTC)

+1 to Jheald's suggestion. Walloping 80+ language labels for taxonomic names or family names or (whatever else fits this categorisation) is crude and ultimately ugly as other wikis come on line rather than a default language neutral name that appears in a typeahead list.  — billinghurst sDrewth 12:55, 1 March 2017 (UTC)

Yes, I have always supported having a single default label (for taxon names, books, movies, songs, etc) to be shown in every language rather than actually adding them eighty or a hundred and forty fold (or whatever). - Brya (talk) 11:28, 4 March 2017 (UTC)

Two points emerge:

1. A "single default label" sounds lovely, but it's just a pipe-dream. There is no indication that such functionality will ever be delivered, let alone in the near or middle future
2. If that is the way forward, why is Succu using a bot to add labels in multiple languages; and why his action acceptable, but this proposal not?

@ValterVB: quickly deleted three hotels from Wikidata without any discussion or notice to us and without any checks, whether they are used in a wiki. Now we miss all the information on Wikivoyage and got broken listings in our current featured article of the month. I would kindly request to undelete the three items and not deleting such items in the future. Wikidata is the only way to share information and save information that are needed in all Wikivoyage language versions on a central place. If we can not save save our items on Wikidata then Wikidata is completely useless to us. -- DerFussi 06:58, 1 March 2017 (UTC)

I restored this one and can restore the other two if one gives me the links. However, this is a serious issue since it was indeed no way to know the info is user on the Wikivoyage. We (the Wikidata and the Wikivoyage communities) must think what would be the best way to mark these items as notable.--Ymblanter (talk) 08:20, 1 March 2017 (UTC)

It seems like we generally need a new feature to show when a Wikidata item is used in a Wikimedia project. Especially given the intention that we want Wikidata based list inside of Wikipedia. @Lea_Lacroix_(WMDE):. ChristianKl (talk) 09:40, 1 March 2017 (UTC)

Hello @DerFussi, Ymblanter, ChristianKl:

It is possible, by clicking "Page information" in the left column on an item page. Then, the section "page properties" contains a box "wiki subscribed to this entity" with the list of all the wikis that use this item. In the case of Volks Mehood Hotel (Q28075839) I find nothing, but here's an example. Lea Lacroix (WMDE) (talk) 09:55, 1 March 2017 (UTC)

Great, thanks Lea. Is there any way we can get read of this extra click (which is a significant burden for admin doing many deletions, myself included) and show directly on the page whether an item is in use?--Ymblanter (talk) 10:11, 1 March 2017 (UTC)

Unfortunately not because of performance reasons. This would become quite ugly for an item like human used many times on many wikis. --Lydia Pintscher (WMDE) (talk) 17:53, 1 March 2017 (UTC)

Oh, but Q64 has sitelinks. We do not delete items with sitelinks. I guess the whole thread is about items used in templates (in particular, Wikivoyage uses Wikidata extensively). I do not think the template usage shows in the information.--Ymblanter (talk) 10:14, 1 March 2017 (UTC)

I have restored the other two items and the Wikivoyage article. Now you can see on https://www.wikidata.org/w/index.php?title=Q28090550&action=info that the hotel item is used on dewikivoyage. --Pasleim (talk) 10:16, 1 March 2017 (UTC)

Thanks so much, for the quick reply and restoring it. I can imagine, it's a very touchy issue to separate such entries from simple advertising (do you have an advertising problem here?) - welcome to the Wikivoyage World. Maybe it's useful to have the usage information direct at the bottom of the item's page. Unfortunately this article is our featured article and the article has full Wikidata integration from infobox to every single listing. I even conntected the openstreet map entry with the hotel's wikidata item. Thanks to everybody here for resolving it quickly. -- DerFussi 10:32, 1 March 2017 (UTC)

"do you have an advertising problem here?" Depends on what you regard as a problem. There are advertising items to be deleted every day. There are much more items to be deleted because all thei sitelinks have been deleted (which would probably make the Wikidata item unused clutter) or because they are nonsense in the first place. --YMS (talk) 11:48, 2 March 2017 (UTC)

As far as the extraclick goes, featurewise it might be useful to add a confirmation dialog when deleting items that are actually used somewhere. ChristianKl (talk) 10:36, 1 March 2017 (UTC)

This is one possible option indeed.--Ymblanter (talk) 10:59, 1 March 2017 (UTC)

No need for a special confirmation dialog. Actually, the "Delete page" page already has several warnings on it (e.g. page is linked somewhere, page has a history of so many versions, ...). Simply adding another warning there ("page is used here:") should be enough. --YMS (talk) 11:48, 2 March 2017 (UTC)

Just to clarify some aspect about the deletion of the elements in general (IMHO):

* About "without any discussion or notice" : the number of deletion it's so high that it's impossible warning all the users, moreover most of the elements were created by BOT. It's more efficiente restore deleted item when some user ask the restore and show that the item is notable, in this case the restore is very fast.

* The task of search of item to delets is based a lot on SPARQL, we have a lot of list that show item that must be deleted, but normally the rules are based on notability policy: No sitelink, no backlink, no source/reference="No notable" (there are some exceptions that require more detailed controls). The control that I done on the item in thiese lists is about the possible elimination of sitelinks (page deleted?, page move to another item? vandalism? etc.)

• To solve the problem highlighted in this topic we need that SPARQL can acces to the info "wiki subscribed to this entity" or alternatively need a template to add to the list, so in case a not notable item is "used" we can do a more complete check. If these solutions aren't possible we can create a new property "Item used in Wikiproject" or "Item used in wikipage" --ValterVB (talk) 12:41, 1 March 2017 (UTC)
• I forgot to say that I exclude from delete process also item with property that are "External identifier" --ValterVB (talk) 12:47, 1 March 2017 (UTC)
  • @ValterVB: I really don't like the "oh, we're so busy" excuse. It's your responsibility as an administrator to check before deleting. Now that we know that the info is available we should check it before deleting something as out of scope. BTW, what is the API call to get this info? Bots and tools being used in the deletion process need that to check it. Multichill (talk) 21:15, 1 March 2017 (UTC)

I don't say "I'm so busy", but the problem is that not notable item increase more than we can delete. In a project like Wikidata rules on delete and on restore must be different than in Wikipedia, everything is much faster. We must use also automatic tools to do this kind of task, but if the opinion is that we must to do a much more thorough check I can report all this kind of item in Wikidata:RFD so more user can check this item. --ValterVB (talk) 21:41, 1 March 2017 (UTC)

I would prefer it if the items get listed in Wikidata:RFD with everyone who edited the item getting pinged and deleted after a week if nobody objects to their deletion.

At the same time it also makes sense to make the data accessible via SPARQL. Besides this usecase, it makes sense to be able to make a query like "hotels in Berlin that aren't listed in de.wikivoyage". ChristianKl (talk) 08:25, 3 March 2017 (UTC)

We already have a lot of report with candidate do delete, someone updated daily other base on SPARQL, we talk about thousand of item or maybe tens of thousands of items. Can we can add all this item in Wikidata:RFD? Based on my experience 90% of this item can be deleted without problem, 9% must be merged or must be restored to a previous state, 1% are problematic and a discussion in RFD is useful.

--ValterVB (talk) 10:20, 3 March 2017 (UTC)

• If a new user get's an item deleted without notice that's demoralizing. I think it would be more friendly to new users to alert them that an item doesn't fulfill our standards and give them a change to improve it, the same way as Wikipedia does it.

Maybe we could put a deletion warning template of a talk page of a items that get flagged. A category page could list all items that currently have the deletion warning template. If the deletion warning template stays for a week, the item comes in your lists to be deleted. ChristianKl (talk) 12:07, 3 March 2017 (UTC)

This is not really possible unless done by bot. We have too many items for deletions and too few admins doing deletions on regular basis, so that alerting every user would severely disrupt the workflow.--Ymblanter (talk) 13:51, 3 March 2017 (UTC)

Is it possible to undelete Q27954647 (Hotel König), too? It was a hotel in the Vienna quarter of Simmering being the host of the 2017 hackathon. --RolandUnger (talk) 06:04, 2 March 2017 (UTC)

 Done--Ymblanter (talk) 06:40, 2 March 2017 (UTC)

Personally I have some doubt with this kind of item. In this case all the hotels are notable, simply add it into a wikivoyage page, use a property from wikidata and the item is automatically notable. Maybe we must think about this. With the same criterium "All can be notable"... --ValterVB (talk) 10:31, 3 March 2017 (UTC)

What's the practical issue here? Having items for Wikimedia lists is an useful task for Wikidata. ChristianKl (talk) 12:07, 3 March 2017 (UTC)

@ValterVB: you seem to be doing quite a bit of harm. user:Spinster is preparing an import and as preparation created Philomene Pirecki (Q28775124), François-Xavier Courrèges (Q28777061), Alison O'Daniel (Q28792361), Marie Voignier (Q28777080), Pierre Toby (Q28777002). You deleted them, she politely asked you to undelete. Now look at the red link, the second one was never undeleted and two others were deleted again on the same day. What are you doing? I think it might be better you take a break. Multichill (talk) 18:49, 3 March 2017 (UTC)

@Multichill: The second was an error, if user warned me I could undelete, for the third can happen if the people create item with only instance of (P31) =human (Q5) and sex or gender (P21), no sitelink no source, no something of useful in object, I restored you can see the statuss of this item. However, now I put all cancellations in RFD so other admin can decide. --ValterVB (talk) 19:37, 3 March 2017 (UTC)

I discovered that en:Airport Road (Ontario) does not have a Wikidata link (I will create it shortly). The article was created in 2015. I thought all new eligible Wikipedia pages eventually get picked up by bot, which presumably did not happen with this article. Does someone know more, e.g. (i) bots were not yet running at the time; (ii) I am wrong about bots at all; (iii) smth else happened?--Ymblanter (talk) 13:02, 4 March 2017 (UTC)

This was created in 2015 but until February 2017 it was a draft. Bots shouldn't create items for not yet complete articles. Matěj Suchánek (talk) 13:09, 4 March 2017 (UTC)

Dear all,

The idea of ingesting heritage data into Wikidata on a large scale is getting more and more traction. To get an overview of what has already been done, have a look at WikiProject Cultural heritage. Several further projects are under way.

In 2017 members of the "Wikidata + GLAM" Community are planning to attend various international conferences and hackathons. I think it would be nice to have a couple of dedicated meet-ups where we can discuss hot issues related to Wikidata + GLAM, where we can exchange experiences, and where the non-initiated can meet those among us who have been sticking around on Wikidata for a while.

From a casual enquiry on the Wikidata + GLAM Facebook group I have gathered the following conferences/hackathons that might be of interest:

• Wikimedia Hackathon, Vienna - 19-21 May 2017
• LODLAM Summit, Venice - 28-29 June 2017
• Wikimania Hackathon, Montreal - 9-10 August 2017
• Wikimania Conference, Montreal - 11-13 August 2017
• GLAM+Wikidata Gathering, Lausanne - 14 September 2017 (proposal)
• Swiss Open Cultural Data Hackathon, Lausanne - 15/16 September 2017
• WikidataCon, Berlin - 28/29 October 2017

If you are interested in issues related to the ingestion of heritage data on Wikidata, please indicate which events you are planning to attend this year by filling in the following Doodle poll

If you are aware of any further events of relevance in this context, please let me know and I will add them to the poll.

--Beat Estermann (talk) 15:52, 4 March 2017 (UTC)

Hello all,

As you know, the Wikimedia hackathon will take place on May 19-21 in Vienna.

During this event, we will organize a documentation sprint to help volunteers to improve the user-level documentation for Wikidata.

During these 3 days, you'll be able to join (IRL or remotely, at any moment) to work on improving and translating the help pages. We suggest a focus on these 3 topics:

• Beginner documentation about Wikidata
• Lua for Wikimedians
• Wikibase installation

We will also organize some workshops (translation tools, illustration...) to help you build a better documentation.

You will find all the information on the related page. If you're interested, feel free to add yourself in the attendees list.

We're now building a list of simple tasks that volunteers could work on during the event. If you have any ideas, parts of the documentation that should really be improved... feel free to add your ideas on the talk page, or if you feel comfortable with Phabricator, directly create subtasks of the tasks listed above.

Thanks a lot, and maybe see you there! Lea Lacroix (WMDE) (talk) 11:03, 2 March 2017 (UTC)

Why focus a Hackathon on improving documentation instead of focusing it on writing code? It seems to me like there are tasks for writing bots to import data that are simple enought o be a Hackathon task. ChristianKl (talk) 11:49, 2 March 2017 (UTC)

There will also be a lot of code-writing. But Léa is working on getting the documentation improved. Especially the installation instructions for Wikibase are a pre-requisite to actually being able to code on it. --Lydia Pintscher (WMDE) (talk) 16:20, 2 March 2017 (UTC)

I agree with ChristianKl. I applaud the effort of improve documentation, but I'm not sure this is the best way to spend our time on the hackathon.

As far as I know most of the Wikibase code is written by the staff of WMDE and apparently this is done in a very agile manner (working code is more important than documented code). If this is important, why aren't the people who actually write the code not spending more time on it? Now it feels a bit like the staff doesn't feel like doing it and it's up to the volunteers to do it. Multichill (talk) 22:03, 2 March 2017 (UTC)

More AGF please :) Staff will be taking part in it. But this is also not just about the tech documentation but also end-user documentation for example that is outside our mandate. We're constantly getting complaints that the documentation is bad. We're doing something about it. No-one is forced to join. There are enough people at the hackathon who are not developers to help with this without taking away from the rest of the event. --Lydia Pintscher (WMDE) (talk) 11:29, 3 March 2017 (UTC)

If the current end-user documentation is problematic, wouldn't it be more straightforward to have on-wiki a Wikiproject that deal with it? It might have a subpage that lists all complaints about the documentation. ChristianKl (talk) 12:41, 3 March 2017 (UTC)

The same could easily be said about code. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:35, 3 March 2017 (UTC)

The key venue to discuss code is phabricator. The key venue to discusses changes to the on-Wiki documentation is the Wiki. ChristianKl (talk) 05:49, 5 March 2017 (UTC)

Hi all. To copy what I wrote on one of the phab tasks [with tweaks and addendum]:

I think I understand [the concerns] (i.e. that developers should spend their valuable time together, working on the really hard problems, and not on writing beginner documentation), but if I may offer a few counterpoint thoughts:

• These (3 documentation tasks) are all-day sessions, and are suitable for drop-in; so if an experienced dev wants to take a break from more complex code-oriented thinking, they can optionally do so here.
• There are usually a small number of newcomer developers in attendance, plus a few experienced-editor non-developers. - These people will (a) be able to provide beginner-perspective insights (to the experienced developers) for why a documentation-change, or a feature-request, or an interface-design-change is desired, and (b) will be able to talk directly to experienced-developers in order to get technically-precise summaries, that they as newcomers/non-developers can then help to document, from a beginner's perspective.
• Documentation problems are so common (throughout the world, not just software!) that they rarely even get discussed in detail. These sessions will give a space for spitballing (sharing/brainstorming/etc) our collective gripes and suggestions. Some of the people who are there, might be inspired to finally fix those longstanding problems! At the very least, a detailed to-do list or options-list can be written down [or added to, if we start it ahead of time, as ChristianKl wisely suggests], and then the gritty detailed work can be done at a slower pace when everyone is back home.

[Addendum] See also, some recent discussion on wikidata-l about these proposed tasks, where there is some interest, and some suggestions. I completely agree that we should start a WikiProject, or other organizing page, ahead of time. Is there an ideal existing location to use, or do we need to create a new page? (It's generally better to use existing pages when possible, otherwise everything fragments even further.) - I couldn't see anything, from a quick glance around, beyond the basics at Help talk:Contents.

I think it would be good if we exchange the order of "Sister Projects" and "WikiProjects" on https://www.wikidata.org/wiki/Wikidata:Community_portal . It would make it easier for new users to discover that we have WikiProjects and engage with them. ChristianKl (talk) 12:21, 3 March 2017 (UTC)

Can the ArticlePlaceholder extension be installed on the production instance of Wikidata? I think it would be great as a way for people to get some idea of how it works on Wikipedias which are testing it. (Especially great would be to see English language output, given the English Wikipedia doesn't have ArticlePlaceholder yet and is unlikely to ever do so – I can look at some of the non-English wikipedias that are testing it in production, but the experience is a bit lacking when I can't read those languages.) The "Create an article" button should be disabled of course. (Test Wikipedia and Test Wikidata have it, but they don't have real data – it would be great for people to be able to see it with real live data from here.) SJK (talk) 05:01, 5 March 2017 (UTC)

I think the developers don't want to use the real data on test instances because of the hassles involved: (1) the real data is a lot bigger than the test data; (2) if they were to use real data, they'd likely use a point-in-time snapshot rather than a live feed, but (3) a point-in-time snapshot might contain problematic material like defamation or doxxing, so they'd have to deal with requests to remove that from the test data post the snapshot time. So I see why fake data is easiest for them. But I think it would be best to install ArticlePlaceholder here so people can see how it works with real data even if they don't speak one of these minor languages it is being tested in production with. SJK (talk) 05:16, 5 March 2017 (UTC)

@SJK: That makes sense. I should have said earlier that I support your proposal as well. —Justin (koavf)❤T☮C☺M☯ 05:46, 5 March 2017 (UTC)

How can I find wikiprojects that have edited in the last 7 days? all of the wikiprojects seem to have at most 9 members, and the last edit is at february. How can I find a wikiproject that has:

1. A decent amount of members, and
2. Been active within 7 days

PokestarFan (talk) 02:15, 5 March 2017 (UTC)

e.g.

• Wikidata:WikiProject sum of all paintings
• Wikidata:WikiProject Movies --Pasleim (talk) 09:13, 5 March 2017 (UTC)

Even on these rather large projects, I find it is hard to know what is happening right now and feel part of something. It would be more motivating to have a precise list of tasks, with some progress marker, and see the number of remaining items go down progressively (or up for good items!). Or at least, to have some people describe what they are doing so that others can come and help. Koxinga (talk) 09:25, 5 March 2017 (UTC)

Well, I think many projects are at about 1% of what could be done. So unless one is self-motivated, one might probably think we are nowhere. BTW Wikidata:Database_reports/without claims by site, Wikidata:Wikivoyage/Lists/Embassies and Wikidata:Database_reports/Deaths_at_Wikipedia attempt to do some progress calculation, but it's obviously somewhat one-dimensional.
--- Jura 09:50, 5 March 2017 (UTC)

Of course, most projects have a very large scope, but specific tasks can be done collaboratively and give a good result in a short time. For example, I like your embassy example and added a few informations. What would be even better is a history of the progress, even if just for an aggregated "completeness" indicator. Koxinga (talk) 21:55, 5 March 2017 (UTC)

Is there an appropriate way to define what types of products or services a shop sells? field of work (P101) is for people. industry (P452) seem too general. What I would like is a logical link to say that bakery (Q274393) sells bread (Q7802). Pauljmackay (talk) 07:51, 5 March 2017 (UTC)

For a bakery "product or material produced" would do, but this will not work for some other shops. - Brya (talk) 12:07, 5 March 2017 (UTC)

Yes I appreciate because a bakery makes produce on site that could work, but I'd like a means for any kind of shop. Pauljmackay (talk) 16:32, 5 March 2017 (UTC)

The description for has characteristic (P1552) indicates that it should apply to non-material qualities, but I see uses that are clearly material. Is there a better property for material features? Or do we need to update the description? - PKM (talk) 23:31, 5 March 2017 (UTC)

Is it ok to use dedicated to (P825), when I want to say to which artist an art exhibition dedicated?--Stolbovsky (talk) 21:39, 1 March 2017 (UTC)

I spot-checked some single artist exhibits, and they use main subject (P921). I'd recommend that. - - PKM (talk) 02:54, 2 March 2017 (UTC)

@PKM: I don't think those are equivalent. "main subject" apparently refers to the topic or content (e.g. of the exhibition). What is used, for example, when a book or film is dedicated to an individual, who is likely not the work's "main subject"? -- Deborahjay (talk) 11:19, 5 March 2017 (UTC)

@Deborahjay:My understanding is the same as yours, I understood the original question to be what property to use for an exhibit "dedicated to the works of". - PKM (talk) 13:56, 5 March 2017 (UTC)

So how would we characterize a solo exhibition displaying portrait paintings by artist George W. Bush of US military veterans and dedicated "in honor of" the latter? -- Deborahjay (talk) 11:21, 6 March 2017 (UTC)

User:ValterVB is mass nominating thousands of items for deletion on Wikidata:Requests_for_deletions. I think there needs to be some community discussion about this. ValterVB's method appears to be simply applying mechanical criteria (such as a SPARQL query) and then nominating all the query results without giving any evidence of having reviewed them. The problem with that is twofold (1) it misapplies the notability policy, which can't be reduced to mechanical criteria (an item may well be notable even if it is near-empty and has no backlinks or sitelinks – if you can identify the concept it refers to, you need to do research to try to determine if sufficient sources exist for it to be notable, and if you can find such sources then obviously it is notable despite the poor state of the item – the answer then is to try to improve the item rather than delete it) and (2) I feel like this overloads the ability of the community to review all the nominations. I think a lot of stuff ValterVB has nominated is actually notable and should be kept but I don't have the time to go through every one and check for valid arguments for notability. I think there should be a policy against mass nominations of this nature. (Mass nomination might be acceptable if it is items in one confined area meeting precise criteria, but not with the broad criteria ValterVB is using.) SJK (talk) 02:13, 4 March 2017 (UTC)

All items ValterVB nominated for deletion have neither references nor sitelinks nor backlinks. How can such an item represent a clearly identifiable entity? --Pasleim (talk) 02:55, 4 March 2017 (UTC)

Pasleim, that is easy. Consider one of the items ValterVB nominated – US pregnancy category A (Q28123615) – can there be any doubt that item refers to a clearly identifiable entity? In very many cases, the labels and descriptions (in conjunction with the instance of) are sufficient for an intelligent person to identify uniquely which concept in reality the item is referring to, and hence make a judgement – after researching the item (e.g. search Wikipedias, search Google, search specialised sources such as Google Scholar, Google Books, research databases such as JSTOR, etc) – make an informed judgement on whether the referred to concept is likely to be notable. But ValterVB shows no sign of having done this – just ran some queries and nominated everything the query returns without thought. The notability policy can't be reduced to such a mechanical process. SJK (talk) 04:13, 4 March 2017 (UTC)

These items seem to be linked to the unused property pregnancy category (P3489). Probably that should be deleted as well if no use can be found for it.

If the property was put to use, I don't think these would have shown up.
--- Jura 11:24, 4 March 2017 (UTC)

The reason the property hasn't been put to use yet is I haven't worked out an easy way to export the data from English Wikipedia (where this is stored in a template) into Wikidata. I looked at using Petscan but couldn't quite work it out. Maybe I will write some code but have been too busy. SJK (talk) 11:38, 4 March 2017 (UTC)

Actually I was looking at using Harvest Templates but there isn't any way in that to provide a mapping from strings to items... it just wants to import string properties. Whereas I think the property works better as an item, which is why I created these items. Actually, now I am working on some scripts to try to do this. SJK (talk) 12:02, 4 March 2017 (UTC)

Here we have a lot of user that can do "miracles" with BOT. Probably if you use this page you can found someone that can do the task in correct way. --ValterVB (talk) 12:38, 4 March 2017 (UTC)

@SJK: I'm indeed doubting that US pregnancy category A (Q28123615) refers to a clearly identifiable concept. FDA changed their pregnancy categories in 2014. Does US pregnancy category A (Q28123615) refer to the pre or post 2014 category system? Nobody can know it. So nobody can improve it. Adding a single reference to a document could be so easy and could save so much trouble... --Pasleim (talk) 13:14, 4 March 2017 (UTC)

@Pasleim:–it is easy to know – letter categories don't exist in the post-2014 US system, they have been replaced by descriptive text, so obviously any US letter category is part of the pre-2014 system. If you would google the topic you would find this out quickly–among other sources, the English Wikipedia article on pregnancy categories explains it. Yes, references would be great, but if one doesn't know what something is google the label and spend some time studying the Google results and in many cases (such as this one) it will be very clear. But if a person nominates things for deletion based on results of a query instead of spending the time to research the item themselves that just means other people have to do that research for them. It is a failure to do due diligence before nominating. SJK (talk) 13:22, 4 March 2017 (UTC)

Please don;t confuse clearly identifiable with clearly identified. Despite the unique interface, this is still a wiki, and we work by incremantal mporvement. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:26, 4 March 2017 (UTC)

@SJK:It's worth noting that till the deletion of items like this would have been happening without any nomination discussion. I think the process of having the nomination out in the open with users being able to comment is an improvement. ChristianKl (talk) 14:01, 4 March 2017 (UTC)

ChristianKl If you look at how English Wikipedia handles it (and I imagine other language Wikipedias do similar, but am not familiar with them), they have a gradation of different processes (1) speedy deletion (for most blatantly obvious cases – admins can do this on their own accord, but there is a process by which non-admins can flag pages for an admin to consider) (2) PRODing (for undisputed low controversy stuff that isn't blatantly obvious), (3) AFD (for disputed / high controversy stuff). I really think Wikidata could do well by adopting some more structure in deletion like that. Another good thing enwiki does is standard deletion reason codes admins have to use when deleting something without discussion in the edit summary. Having more structure and more transparency would be good, because this makes me worry that a lot of stuff is getting deleted when if someone made the effort it might be salvageable. SJK (talk) 14:07, 4 March 2017 (UTC)

I agree with your core concern. I think this particular Mass deletion nominations is a change towards more transparency in our process and thus I feel like ValterVB shouldn't be too strongly criticized for it.

I agree that standard deletion reason codes would be great (it would also be useful to make the label of a property still visible after the deletion of that property. ChristianKl (talk) 14:17, 4 March 2017 (UTC)

deletion is not a quality improvement process. better to talk to item creator and solve problems. mass deletion is particularly bitey. Slowking4 (talk) 09:33, 5 March 2017 (UTC)

• If we stay with a automated deletion nomination process like this, it would be good to use the item template {{Q|...}} instead of the plain number. It might also be nice to have a bot that automatically flags items that did get links after the item was nominated, so that it get's clear that the item has been improved and doesn't need to be deleted. ChristianKl (talk) 09:03, 6 March 2017 (UTC)

The problem: Q2502275 (Ury) vs. Q406167 (URY). Why can't Wikidata distinguish between uppercase and lowercase? --Harry Canyon (talk) 05:50, 5 March 2017 (UTC)

What do you mean with the suggestion that Wikidata can't distinguish between the two? ChristianKl (talk) 05:58, 5 March 2017 (UTC)

@ChristianKl: Sorry, wrong item, I mean Q2502275 (Ury) vs. Q406167 (URY). Both can not be provided with the description "Wikimedia disambiguation page". --Harry Canyon (talk) 06:04, 5 March 2017 (UTC)

You can give on the description "Wikimedia disambiguation page for lower case" and the other "Wikimedia disambiguation page for upper case". ChristianKl (talk) 07:17, 5 March 2017 (UTC)

This is just a makeshift solution and does not really solve the problem. It would be better, Wikidata could differ between upper-case and lower-case, as is also Wikipedia. --Harry Canyon (talk) 08:56, 5 March 2017 (UTC)

I think these items should be merged. Pages like de:Ury, it:URY and fr:URY refer to both "Ury" and "URY" so making a distinction between these two concepts on Wikidata is pointless. The only conflict is enwiki but the articles en:Ury and en:URY (disambiguation) are obivous dublicated pages because they both refer to "Ury". --Pasleim (talk) 09:12, 5 March 2017 (UTC)

At the beginning Wikidata was case sensitive, then developer have changed without a clear explanation. However, it's possible to bypass this constraint --ValterVB (talk) 17:01, 5 March 2017 (UTC)

Probably, there are still a lot of items that violate this rule because when they have changed this, they did not bother to provide lists of items that violate the rule or a tool to control them. This is also the reason why sometimes the merge does not work --ValterVB (talk) 17:06, 5 March 2017 (UTC)

I've merged the en.Wikipedia pages. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:12, 6 March 2017 (UTC)

At the head of my watchlist there's a couple of items,

• Selected requests for comment
• Current property deletion requests
• Current property proposals

The list of current property deletion requests includes BBC News Democracy Live ID which was raised last October, resolved in November, and archived in December. It's not been a live discussion for 3 months. Why's it still listed as a current request? Cabayi (talk) 12:17, 5 March 2017 (UTC)

The list needs to be updated by hand. I have just done it, so there should be shown only relevant links now. Matěj Suchánek (talk) 13:00, 5 March 2017 (UTC)

Matěj Suchánek, Thanks, Cabayi (talk) 13:11, 5 March 2017 (UTC)

& can't link to Wikidata:PFD#doubles record (P555) and singles record (P564).

It shouldn't prevent you from finding the request and/or to contribute to Wikidata.

Jura, that's a poor reason to leave the problem unfixed. Cabayi (talk) 07:40, 6 March 2017 (UTC)

Matěj Suchánek, embedding an {{Anchor}} (with the Property's # rather than its label) in {{Rfd links}}, and pointing {{PropertyRFD}} at the anchor rather than a potentially incorrect title would provide a more reliable deep link into Wikidata:PFD. My 2¢. Cabayi (talk) 08:47, 6 March 2017 (UTC)

What you suggest is nice and actually simple. I think I'll do it. Matěj Suchánek (talk) 13:25, 6 March 2017 (UTC)

When adding an url component "3066278/STEWART, JOHN EBENEZAR/" to this property it converted the generated url to have '+' instead of the spaces. If I force the snippet to have underscores replace the spaces this gets around the problem, that does ot seem a robust solution. It was suggested that toollabs:wikidata-externalid-url may be able to be utilised to resolve this issue. Thanks.  — billinghurst sDrewth 13:00, 5 March 2017 (UTC)

@billinghurst: you should only add the integer (3066278) to produce the url (http://www.cwgc.org/find-war-dead/casualty/3066278/), don't include the slug. Multichill (talk) 14:42, 5 March 2017 (UTC)

• 19:32 - ‎Q17332687 nominated for deletion
• 19:51 - item deleted
• 20:33 - deletion discussion archived

It would be nice if the label of a deleted item could be posted as actual text in the deletion discussion, so a quickly-deleted item is less obscure to non-admin participants.--Pharos (talk) 21:57, 6 March 2017 (UTC)

On average, 793 items get deleted every day! With this amount it's impossible to start a discussion on all nominated items. Administrators have quickly to decide to either speedy delete and item, speedy keep an item or wait for futher user comments. ‎Q17332687 was certainly a candidate for speedy deletion. --Pasleim (talk) 22:12, 6 March 2017 (UTC)

Actually this one is controversial. It's part of this batch of deleted articles at the Dutch Wikipedia. These people are all elected in Belgium to the provincial council (Q2019652) and I would probably not have deleted them at the Dutch Wikipedia. So yes, these people are in my opinion notable. Multichill (talk) 22:20, 6 March 2017 (UTC)

The content on ‎Q17332687 did not indicate that it is about a politician or a person from Belgium. Searching the web for the name of the person returned social media profiles of a worker from the Netherelands, of a Belgium Taekwondo fighter, a German comedian, a Beglium politician, an Instagram user with 25 follower, a Youtube user with one playlist, etc... --Pasleim (talk) 22:48, 6 March 2017 (UTC)

Earlier today, I left comments on six discussions at Wikidata:Properties for deletion:

• Wikidata:Properties for deletion#Property:P3122
• Wikidata:Properties for deletion#WHO international non-proprietary names ID (P3350)
• Wikidata:Properties for deletion#Property:P3417
• Wikidata:Properties for deletion#PORT film ID (P905) and PORT person ID (P2435)
• Wikidata:Properties for deletion#Booking.com hotel ID (P3607)
• Wikidata:Properties for deletion#type of kinship (P1039)

in each case saying "I think that this discussion is resolved and can be archived. If you disagree, don't hesitate to replace this template with your comment.".

User:Jklamo has mass-reverted those edits, though they did not avail themself of the opportunity to leave a comment in any of them.

There has been no meaningful change of consensus in any of those sections for some time, and all lack consensus to delete (most show strong consensus to keep). The earliest was opened over a quarter of a year ago; even the most recent has been open for over three weeks.

Please can someone either restore my comments; or say why the individual discussions are not resolved; or at least close them? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:55, 6 March 2017 (UTC)

As far as I understand it's the choice of individual projects whether they want to import data from Wikidata. If Wikispecies doesn't want to import data frokm us, they don't have to do so and it's not up to outside parties to tell them to change their ways. ChristianKl (talk) 20:40, 6 March 2017 (UTC)

Don't get the question. The templates for vandalism are templates that you use to discourage users from doing bad edits. Or do you need to find them and get familiar with? Take a look at Category:User warning templates. Matěj Suchánek (talk) 15:17, 7 March 2017 (UTC)

Edit: OK, I found this problem actually has two parts.

• First, when you're typing "Earth" in the search box, the Earth (Q2) will indeed appear as the first result. HOWEVER, when you press "enter", it doesn't go to the first result like Wikipedia, instead, it goes to the last option, "pages containing 'Earth'".
• The second part of the problem is that the "Earth" page is not in the very first results of the above search result. Actually, it's not even in the first 500 results.--Fireattack (talk) 05:52, 1 March 2017 (UTC)

For what it's worth, I don't find much value in the search bar on Wikidata. I often use a Google search containing the item I want to find and "wikidata", and it works just fine. Maybe Wikidata could shift to a Google custom search? Icebob99 (talk) 13:48, 1 March 2017 (UTC)

The search on Reasonator is also quite useful, even if it only reproduces the results of the ordinary search-box search, but with better annotation. IMO the Reasonator gadget is definitely worth turning on in your Preferences, if you haven't done so already, to add a sidebar link to Reasonator into your sidebar for every item page.

Task T110648

Here's what seems to be the Phabricator ticket for the search results being rubbish. There doesn't seem to have been a lot of work since the end of 2015.

Maybe you could mirror what I have sometimes seen for languages by using Property:P571 for the period (e.g. Q50868) and Property:P2341 for the place (e.g. Q35497). Parikan (talk) 05:12, 2 March 2017 (UTC)

Thank you; that sent me hunting. I think time period (P2348) "historic period or era in which the subject occured" will work very well for time, and indigenous to (P2341) will work for most issues of place. - PKM (talk) 00:31, 3 March 2017 (UTC)

It would be useful if you could collect your observations about expressing time and place in the Wikiproject Historical Place.

Transferred from: Wikidata:Contact the development team#External wiki sites in articles.

Do you thing it would be a good idea to treat external wiki sites like IMSPL or sites of Wikia – that also have encyclopedic organisation of content as a "semi-internal" wiki projects? Let's say, instead IMSPL is an External identifier it would provide linking below Wikimedian links. So: Wikipedia, Wikisource ... Other sites and External wiki sites. For Johann Sebastian Bach there would stay:

--Janezdrilc (talk) 18:23, 1 March 2017 (UTC)

We have external-id's to link to the Wiki's to which we want to link. What do you consider to be the problem with the current solution? ChristianKl (talk) 18:59, 1 March 2017 (UTC)

The current solution is great, I just thought maybe it would be better to have all wikis on one "pile". --Janezdrilc (talk) 19:42, 1 March 2017 (UTC)

The current process means that we check whether a website is notable enough to get the links. I don't see why we should get rid of that step. ChristianKl (talk) 07:52, 3 March 2017 (UTC)

I think it's good for Wikidata to link to external wikis, but they should be kept in the "external identifier" section rather than the "internal interwikis" section. If we include them like another Wikimedia Foundation wiki, we risk giving the false impression that they are part of Wikimedia, which might make them feel belittled and bring us unwanted controversy.

but somehow it stopped working. I even concluded that items didn't have images as they weren't displayed. Maybe it's just my other config that breaks it.

Firstly, please provide the relevant QIDs (like Jean Calas (Q360000)) when you mention items. From what information you do give, it seems that one item is about a person, the other (Jean Calas affair (Q28650272)?) about an event, so they are not suitable for merging. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:21, 8 March 2017 (UTC)

Wikipedia pages linked to Jean Calas (Q360000) and Jean Calas affair (Q28650272) speak about exactly the same things (biography + affaire) but in Wikidata it's two different items. Tubezlob (🙋) 13:56, 8 March 2017 (UTC)

For those interested in Chinese labels, I just processed over 45,000 "zh" labels of places to check if they were simplified or traditional text. Found out that close to 9,000 of the labels had one or more traditional character in them. This was done by simplifying the labels using the Open Chinese Convert (OpenCC) library and comparing with the original. What is the policy over "zh" labels in Wikidata, are they expected to be simplified or traditional? I'm planning to add the 9,000 simplified labels to the "zh-hans" label, should I also be fixing the "zh" labels or should it be left as it is?

Please check this spreadsheet with the full list of items with a traditional "zh" label and the simplified "zh>zh-hans" label to compare the difference --Planemad (talk) 08:07, 7 March 2017 (UTC)

@Planemad: Chinese speaker here. To encourage people to contribute, the gentlemen's agreement is that the preference of the first contributor to each bit of text should be respected. If the label is simplified, then the traditional version (and regional variants) can be added as an alias and vice versa. The Chinese Wikipedia doesn't even discourage mixed prose because editors from different Chinese-speaking regions should be encouraged to collaborate. So there is no need to "fix" anything.

Direct translations to zh-hans or zh-hant are generally discouraged on multilingual Wikimedia projects because this creates additional curation workload. The recommended method is to create one zh version, then use meta:Automatic conversion between simplified and traditional Chinese to generate and adapt other variants. You can see this at work in e.g. wm2013:Must-read_tips/zh. Deryck Chan (talk) 14:01, 7 March 2017 (UTC)

@Deryck Chan: Thank you, that makes it clear there is no need to update the existing "zh" labels. There are however a handful of cases where i've found traditional text in "zh-hans" or "zh-cn", i'm guessing this should be ok to fix? Aside from that i'll start uploading the automatically converted text into "zh-hans" --Planemad (talk) 16:55, 7 March 2017 (UTC)

@Planemad: Depends on how big your "handful" is. There are occasions when a bot might detect false-positive "traditional" characters in simplified text and vice versa due to inadequate contextual awareness. I'd prefer to have a human look at the list before automatically converting all of them by bot, unless the amount is so large to be unmanageable. Deryck Chan (talk) 22:47, 7 March 2017 (UTC)

@Deryck Chan: If you are asking about LanguageConverter usage of /zh pages which are created by Translate extension, it's really a tricky thing for us, cf. phab:T106131 and phab:T150083. --Liuxinyu970226 (talk) 05:13, 9 March 2017 (UTC)

@Liuxinyu970226: - No, I'm talking about Planemad's request above, where his program identified a number of zh-* labels that have incorrect variant tags (like a Simplified Chinese label tagged as zh-hant). Thanks for letting me know those phab tasks though; I've added my comments. Deryck Chan (talk) 11:59, 9 March 2017 (UTC)

Hi, I couldn't find any documentation for Wikipedia redirect pages in Wikidata. I found an item, Juan Sebastián Elcano (Q18191798), that was the item for a redirect page. I can't merge the two items because both have Wikipedia site links. What do I do for redirects? Thanks, Icebob99 (talk) 14:53, 8 March 2017 (UTC)

It starts with the question of whether the two items are the same conceptual entity. Without knowing Korean that's hard to tell in this case. If it's the same conceptual entity you can remove the redirect link and merge. On the other hand, if it's a different conceptual entity, don't merge and keep the links intact. ChristianKl (talk) 15:51, 8 March 2017 (UTC)

I don't know how to create redirects other than merging them. PokestarFan (talk) (My Contribs) 19:59, 8 March 2017 (UTC)

@Icebob99, -revi, ChristianKl, PokestarFan: It's just an alias name of Juan Sebastián Elcano (Q201510), so  Done. --Liuxinyu970226 (talk) 05:18, 9 March 2017 (UTC)

Why would we link a redirect? They change, they will not be moved so links will not automatically follow, they are hardly notable. They are strewn around the place like confetti as they are considered cheap, so what is the value of listing them?  — billinghurst sDrewth 11:25, 9 March 2017 (UTC)

It isn't worthwhile to have items for the purpose of representing redirects. If there's however a reason for the item to exist, the redirect is valuable. I recently created the item fingerless glove (Q28865095). It's a well defined concept but it doesn't have it's own Wikipedia article. Linking to the redirect however allows a user to read what Wikipedia has to say about fingerless gloves.

Listing redirects also helps with interwiki links. ChristianKl (talk) 11:46, 9 March 2017 (UTC)

According to the English Wikipedia: The Allied High Commission (...) was established by the United States of America, the United Kingdom, and France after the 1948 breakdown of the Allied Control Council to regulate and supervise the development of the newly established Federal Republic of Germany (West Germany).

In my opinion, something that regulates and supervises the country it is in can not be called an embassy. An embassy only has a diplomatic role, it does not regulate nor supervise the country it is in.

So, what should the Allied High Commission (Q314974) be an instance of?

Thank you! Syced (talk) 06:29, 9 March 2017 (UTC)

I agree that it is not an embassy. - Brya (talk) 06:37, 9 March 2017 (UTC)

It is a wikt:commission no. 4 "body or group of people, officially tasked with carrying out a particular function" and definitely not an embassy. That the commonwealth of nations use "high commission" rather than embassy for their inter-governmental relationships is an arcane difference, and more relates back to the single head of state for many of them, and fits within the definition though only due to its broadness, not its functionality.  — billinghurst sDrewth 11:31, 9 March 2017 (UTC)

FWIW, the Commonwealth "High Commissions" probably started out with more of a regulat[ory] and supervis[ory] role, not unlike the case described. They have evolved into embassies over time, though certainly they do fill that role today. StevenJ81 (talk) 15:28, 9 March 2017 (UTC)

It is not just a commission; something more should be added. And, apparently this commission never served as an embassy. - Brya (talk) 05:51, 10 March 2017 (UTC)

• galvanoplasty (Q15031376)
• electrotyping (Q6456484)

These two need to be cleaned up or merged. In particular, either is currently a subclass of the other.

But Q6456484 appears to be a subtype of the other, and most wikilinks should be moved to the other (some may even need to be moved Q17708655).

But I know too little of this subject to be able to tell which should go where, and which should be a subclass of which.

Hi guys, I see that wikipedia in all language use the USDA database. Some users just go to the website and fill all the data in the template responsible for showing that kind of stuff. Someone skilled in programming could just make a bot, gather all the information there and put here on wikidata, later on update those articles that use this data with just some sort of link to here.

I don't know if I was very clear about my idea but the idea is to reuse information, not copy it (or at least try to just make one copy of it and reference it somewhere else). --Guiwp (talk) 20:53, 10 March 2017 (UTC)

Hi, Apologies for cross-posting this, I just want to make sure we reach the right folks.
The Wikimedia Foundation is hiring a product manager for multimedia support/features and, most immediately, the structured data on commons project. We think it would be tremendously helpful if that person was already a member of the Wikimedia movement.  Given that the structured data project is closely tied to wikidata, I wanted to make sure folks on this list were aware.

This topic was previously discussed, but since population density property proposal was rejected, I'd like to see what to do with existing usages of density (P2054) for population density. Should I just delete them? Should we have some other property - which one? Most of existing usage are cities, and these numbers (which are now unitless) are useless in the form they are now and use wrong property, violating its constraints. Ideas? --Laboramus (talk) 06:07, 11 March 2017 (UTC)

Population density can be derived from population (P1082)/area (P2046), so there is no need to have a property for this. I support deleting them where we know this information. Matěj Suchánek (talk) 09:16, 11 March 2017 (UTC)

Concur that we don't need something for population density in situations where the area and total population are known. What do we do in situations where one or both of those are missing, but we do have a reliable density figure? Lankiveil (talk) 13:41, 11 March 2017 (UTC).

If the property has been improperly utilised, the incorrect usage should be removed, and the labels update to better describe the purpose.  — billinghurst sDrewth 15:58, 11 March 2017 (UTC)

Okay, you've convinced me. I am using QuickStatements to import all 825 fire stations now. (I could use mix'n'match too but QuickStatements is quicker.) When QS is done with the fire stations, I'll do the police stations too. (Possibly some of these are non-current/historic fire/police stations as opposed to active ones, but I guess if that is true people will work it out eventually.) I'm also going to try importing all the coordinates after I get some sleep. SJK (talk) 13:54, 11 March 2017 (UTC)

Wikivoyage has "listings" with an image and a Wikidata item. For instance, the Louvre listing has both the name of a Commons image and the relevant QID.
I created and uploaded a list of the QID-Commons image couples here.

• How should we identify the company producing a trade fair? manufacturer (Q13235160) is a profession, so that's not right; production company (Q11396960) is specifically related to media and entertainment.

Hey folks,

I would like to do graph traversal starting from a given node on multiple properties. I found in examples query for searching children of Genghis Khan:

PREFIX gas: <http://www.bigdata.com/rdf/gas#>

SELECT ?item ?itemLabel ?pic ?linkTo
WHERE
{
  SERVICE gas:service {
    gas:program gas:gasClass "com.bigdata.rdf.graph.analytics.SSSP" ;
                gas:in wd:Q720 ;
                gas:traversalDirection "Forward" ;
                gas:out ?item ;
                gas:out1 ?depth ;
                gas:maxIterations 4 ;
                gas:linkType wdt:P40 .
  }
  OPTIONAL { ?item wdt:P40 ?linkTo }
  OPTIONAL { ?item wdt:P18 ?pic }
  SERVICE wikibase:label {bd:serviceParam wikibase:language "en" }
}

This is all nice but I would like to do the traversal on more properties, e.g. instead of only following 'child' branches I would like to traverse also father/mother/spouse and build full family trees.

I tried with gas:linkType wdt:P40/wdt:P25* . and putting OR but nothing worked. Also, any idea where can I find API description for gas?

Docs for RDF GAS API are here. But as far as I know you can't traverse using multiple properties. You can still traverse recursively using *-notation or UNION statements (BlazeGraph does not support elt{1,n} syntax, but other features from property path spec are supported). For example, here is a query for your needs:

SELECT ?level ?item ?relation ?linkTo ?itemLabel ?pic
{
  hint:Query hint:optimizer "None"
  { BIND(0 AS ?level) BIND(wd:Q7200 AS ?item) } UNION
  {
    VALUES ?relation { wdt:P22 wdt:P25 } 
    { BIND(1 AS ?level) BIND(wd:Q7200 AS ?linkTo) }
    UNION
    { BIND(2 AS ?level) ?linkTo wdt:P22|wdt:P25 wd:Q7200 }
    UNION
    { BIND(3 AS ?level) ?linkTo (wdt:P22|wdt:P25)/(wdt:P22|wdt:P25) wd:Q7200 }
    UNION
    { BIND(4 AS ?level) ?linkTo (wdt:P22|wdt:P25)/(wdt:P22|wdt:P25)/(wdt:P22|wdt:P25) wd:Q7200 }
    ?item ?relation ?linkTo
  }

  OPTIONAL { ?item wdt:P18 ?pic }
  SERVICE wikibase:label {bd:serviceParam wikibase:language "en"}
}
ORDER BY ?level

Try it!

Hoi, it is suggested that I use these properties to identify items that are part of a project. For me the combination would be First identify the Catalog and then an associated code. The code is of lesser importance. When I look at Chihuaha I find that the catalog shows as one of the statements.

This is exactly why we proposed a property that does show. A Catalog is a statement that is of no intrinsic value except to the project itself and it is therefore not really usable. So can we please decide that we either have properties for individual projects or mend the way Catalog and Catalog code works. NB it makes better sense to have the catalog first and the code as a qualifier. Thanks, GerardM (talk) 08:26, 26 February 2017 (UTC

Discussion is at Wikidata:Property proposal/Black Lunch Table ID. The catalogue in this case would be an item for "Black Lunch Table"; the code would be the "Black Lunch Table ID", in the format "BLT-######". I'm not clear why this doesn't meet your requirements. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 21:47, 27 February 2017 (UTC)

What I need is to identify an item as part of the "catalog". This does not need to show in the same way as an external source does not need to show. The result is something like this as you can see this functions in queries. Thanks, GerardM (talk) 10:37, 28 February 2017 (UTC)

We use the Catalog for the Black Lunch Table. In stead of keeping the spreadsheet, we are replacing it with the information in Wikidata. In effect it replaces both the spread sheet and allows for the replacement of multiple Wikipedia lists. A qualifier is used to indicate the location of an editathon. This allows for the use of the same data for an additional list. By including the "red linked" articles in Wikidata there is a complete list that can be used using Listeria on multiple Wikipedias. Articles are written in multiple languages. Thanks are due to multiple people for contributing their ideas and some queries that make it obvious that Wikidata is a superb tool for managing Wikipedia projets. Thanks, GerardM (talk) 09:36, 7 March 2017 (UTC)

In contrast to the Women in Red Wikidata-based lists here en:Wikipedia:WikiProject Women in Red/Missing articles by occupation/Animators and cartoonists and here en:Wikipedia:WikiProject Women in Red/Meetup/37#Work lists, which are somewhat horrifyingly manually managed, the very systematic and organized methodology described above that Gerard came up with will allow for metrics and usability testing -- as well as cross-functionality between Wikipedia and Wikidata that is very rich in future pathways. It will also be a huge push to new Wikipedia editors to actually use and understand the power and functionality of Wikidata as it relates to Wikipedia as well as how Wikidata is serving as a semantic backbone of Wikipedia, as a repository itself, and as a query-rich database. It's an excellent, effective project and can be transferred across user groups and chapters as a skillshare and methodology to automate task lists. -- Erika aka BrillLyle (talk) 13:04, 7 March 2017 (UTC)

Hoi, I use Catalog but it has a previous meaning and consequently it is seen as sub optimal. The question is what to do. I want for simplicity's sake a property for a Wikimedia project where it is used to manage a group of items that cannot be otherwise be identified by a query. That or the current use is accepted/acceptable.

Also in many articles it is identified that an artist has objects in the permanent collection of a GLAM. It is suggested to me to use the property "Property:P1343" because "a GLAM must have a description for the artist". As this is not necessarily public, a property specific to this situation "has material in collection" "GLAM" seems like a good idea. For those GLAMs that have identifiers, the identifier could be used as a reference. Thanks, GerardM (talk) 19:40, 12 March 2017 (UTC)

When creating a data item for a book or other work, is the original (first) edition considered an "edition" has edition or translation (P747) and given a separate data item from the primary data item for the work, or should the first edition be part of the primary data item? --EncycloPetey (talk) 05:25, 9 March 2017 (UTC)

@EncycloPetey: If there are no other editions (which will be true for a great majority of works) then it seems unnecessary and unhelpful to have separate data. Otherwise, editions of a book have differences between them--it's not necessarily the case that the first edition is the "canonical" or "master" copy. —Justin (koavf)❤T☮C☺M☯ 06:43, 9 March 2017 (UTC)

@EncycloPetey: I believe that it should be, and I encourage you to separate them with a different approach. We need to separate the intellectual idea (the work) from the physical rendition (the edition, in whatever form). A lecture/speech given at a point in time can have edition which is published (and with these I do two items.) A work/book can become a movie, whereas an edition would not become a movie. From the original expression of the idea can spring many formats.  — billinghurst sDrewth 11:20, 9 March 2017 (UTC)

True, but I am trying to nail down the place where we draw the line. For example, is the First Folio of Shakespeare a "work" or an "edition"? Even that question is not as simple as it sounds, since we have the question of multiple printings and facsimile "editions", which are not new editions. --EncycloPetey (talk) 14:37, 9 March 2017 (UTC)

@EncycloPetey: It is problematic when editions of a work fork. The number of editions fails, and we should probably stop trying to put edition numbering of such works. They are all "editions of" the work, and the system utilised here lacks the maturity, of information density to assist. Best you can do is use the other information like publication year, editor, publisher to better identify the edition that you have.  — billinghurst sDrewth 16:05, 11 March 2017 (UTC)

@EncycloPetey: +1 on having a different entity for the work and for the edition, especially as we can't know that there will be no more edition of a work in the future, and unmixing work and edition claims then would be a mess. If you haven't yet, you may want to have a look at the WikiProject_Books where those modelization issues are discussed -- Maxlath (talk) 12:47, 9 March 2017 (UTC)

I've looked, but it usually isn't helpful for the issues I'm dealing with. --EncycloPetey (talk) 14:37, 9 March 2017 (UTC)

Follow-up Question: So, it the primary data item is for the "work", and not for any specific edition / publication, does that mean that the main data item for a work should not have any publication information? That the publication information about each edition should be placed on separate data items from that of the work proper? This seems the logical result. And how will this impact WP projects whose infoboxes rely upon data about a work from Wikidata? --EncycloPetey (talk) 15:22, 12 March 2017 (UTC)

I would think that for a published work that the "first" publication date is required for infoboxes. It is when the intellectual property (copyright) takes effect, and the alternates in copyright law flow through as per each set of legislation. Where I have done lectures I have always put the date of presentation for the event, then done editions with the year of publication.  — billinghurst sDrewth 01:28, 13 March 2017 (UTC)

The actual topic involved, that is weft, is quite clearly not a term.

Hello, long time no see.

South Korea has no official "President" for now, so prime minister is acting as president. Its Constitutional Court also has no president as the term has expired, so other justice is acting as a president. I think some sort of qualifier should be used, but I don't have any idea on what Property and item to use to denote that.

(Removing it isn't a good option imo as (s)he indeed served as a president of given organization.) — Revi 09:24, 18 March 2017 (UTC)

While the role is acting from a political point of view, is it acting from a governmental perspective? Does the person have all the powers, or any qualification of their role? I would record it with the dates, the predecessor and the successor component. If they do not have full powers, then it is a different role and should be labelled differently and only look to further qualify if the role that they fill is not a full role, and if it is not the full role, then it is separate and should be defined differently. For Australia they have a Governor-General of Australia (Q610669) and when not filled they have an Administrator (Australia) (Q4683598).  — billinghurst sDrewth 01:45, 19 March 2017 (UTC)

The Constitution states prime minister (then the ministers based on predefined orders) is acting as president when the seat is vacant. By law they have full power to exercise anything as a president (but of course politics are complicated). So it seems there's no way to do this with qualifier. — Revi 03:47, 19 March 2017 (UTC)

I am not an expert in South Korean constitutional law, but it sounds in this case that this person is not "The President", but still just "The Prime Minister", and part of the duties and powers of the Prime Minister is to exercise the powers of the Presidency when that position is vacant. In this case, it might not be appropriate to list them as "President" at all and it might not be appropriate to list them as such. Perhaps a South Korean equivalent object to acting president (Q3153784) might be a way forward if we want to track this? Lankiveil (talk) 04:53, 19 March 2017 (UTC).

Maybe. I'll stick to that. — Revi 05:29, 19 March 2017 (UTC)

If there is a prescribed position in the constitution, then create it, and it sounds as it sits there as a type of w:dormant commission. Billinghurst 06:52, 19 March 2017 (UTC)

Yeah, it depends. In general, I'd qualify it with P794 (P794) acting president (Q3153784). At least that is the solution suggested for other offices at Property talk:P39.

There seems to be country house (Q16884952) and English country house (Q1343246) both of which point at English country house. Should the Wikidata items be merged? And should the result be called "country house" or "English country house". If the latter, what about similar types of buildings in other countries? Pauljmackay (talk) 16:36, 5 March 2017 (UTC)

Well, one of them is a redirect. I thought redirects shouldn't have their item? MechQuester (talk) 16:38, 5 March 2017 (UTC)

It doesn't need merging as it's possible to have country houses outside of the UK. On the other hand English country house (Q1343246) is clearly a subclass of country house (Q16884952). ChristianKl (talk) 18:42, 5 March 2017 (UTC)

It's interesting that the German "Land haus" is in with mansion (Q1802963). I am not convinced of the need for a separate "country house" item between English country house (Q1343246) and mansion (Q1802963), if the only sitelink is to a redirect. Jheald (talk) 08:34, 6 March 2017 (UTC)

The German word is "Landhaus" and not "Land haus" but that's besides the point. The term doesn't say anything about a house being located in Germany or having anything to do with Germany. The term can easily applied to many houses outside of Germany. Most entities that qualify are likely outside of Germany. On the other hand the term "English country house" is quite specific and refers to houses inside of England. Given that it does equal "country house" I have moved the Wikilink to that item. ChristianKl (talk) 09:19, 6 March 2017 (UTC)

So you've just broken all the interwiki links that "Landhaus" previously had. Is that really an improvement? It's part of what Wikidata is, that there's a bit of elasticity in the concepts that our items match to. The question was not whether "Landhaus" was a good match for "English country house" -- there's already an article "English country house" on dewiki. The question is whether "Landhaus" (and country house, generally) is a good enough match for mansion (Q1802963), to be worth keeping the interwiki links together. That, to me, is a much more evenly balanced question. Jheald (talk) 09:59, 6 March 2017 (UTC)

You can have a mansion that's in a city. Being in a city doesn't conflict with the concept of what a mansion happens to be. It does conflict with the concept of a "country house" or a "Landhaus". En.Wiki says "Fifth Avenue in New York City, was lined with mansions". That shows to me that a different thing than "Landhaus" is meant.

Given that people can specify the identity of a building via P31 it's useful to have the labels of different languages mean the same thing even when that means that there are less interwiki links. ChristianKl (talk) 11:14, 6 March 2017 (UTC)

A country house doesn't cease to be such just because someone moves an administrative line on a map. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:50, 6 March 2017 (UTC)

The linked controlled vocabulary says: "Note: Houses in the country as opposed to an urban area, especially houses that are large, have substantial property, and are used seasonally." It's not simply the architecture of the house but whether it's in the country or the city matters. ChristianKl (talk) 14:55, 7 March 2017 (UTC)

You appear to be confusing (or at least making free with the ambiguity between) the meanings of different phrases. A building that is in a city may still be in the country. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 00:03, 14 March 2017 (UTC)

There are a lot of small changes happening in the next couple of weeks, and I wanted to give you all a quick heads-up about them. Please share this information with other people/languages/projects that will be interested:

• There's a change to how columns in reference lists are handled, at the request of the German Wikipedia. This change will improve accessibility by automatically formatting long lists of <ref>s into columns, based on each reader's screen width.
  • What you need to do: Nothing visible is happening now. If your project uses the normal <references /> tag (or doesn't really use refs at all), then file a Phabricator task or just tell me, and I'll get your wiki on the list for the next config change. If your project uses a "reflist" template to create columns, then please consider deprecating it, or update the template to work with the new feature.
  • I'm assuming that this won't affect Wikidata much, but if I'm wrong, then please let me know. :-)
• The label on the "Save changes" button will change on most smaller projects tomorrow (Wednesday) to say "Publish page". This has been discussed for years, is supported by user research, and is meant to be clearer for new contributors. (Most of us who have been editing for years don't even look at the button any more, and we all already know that all of our changes can be seen by anyone on the internet, so this doesn't really affect us.)
  • If you have questions or encounter problems (e.g., a bad translation, problems fixing the documentation, etc.), then please tell me as soon as possible.
  • When we split "Save page" into "Save page" and "Save changes" last August, a couple of communities wondered whether a local label would be possible. (For example, someone at the English Wikipedia asked if different namespaces could have different labels [answer: not technically possible], and the Chinese Wikipedia has some extra language on their "Save page" button [about the importance of previewing, I think].) Whether the Legal team can agree to a change may depend upon the language/country involved, so please ask me first if you have any questions.
• As part of the ongoing, years-long user-interface standardization project, the color and shape of the "Save changes" (or now "Publish page"), "Show preview" and "Show changes" buttons on some desktop wikitext editors will change. The buttons will be bigger and easier to find, and the "Save" button will be bright blue. (phab:T111088) Unfortunately, it is not technically possible to completely override this change and restore the appearance of the old buttons for either your account or an entire site.
• Do you all remember last April, when nobody could edit for about 30 minutes twice, because of some work that Technical Ops was doing on the servers? The same kind of planned maintenance is happening again. It's currently scheduled for Wednesday, April 19th and Wednesday, May 3rd. The time of day is unknown, but it will probably afternoon in Europe and morning in North America. This will be announced repeatedly, but please mark your calendars now.

That's everything on my mind at the moment, but I may have forgotten something. If you have questions (about this or any other WMF work), then please {{Ping}} me, and I'll see what I can find out for you. Thanks, Whatamidoing (WMF) (talk) 19:06, 13 March 2017 (UTC)

Local Wikipedias, local Project chats (bad idea, probably). --Edgars2007 (talk) 07:20, 14 March 2017 (UTC)

I recently became aware of entries like 2221 (Q28913545) or 2229 (Q28913554) (the latter likely should be "2229") on future years, created by User:PokestarFan, that contain the same label for hundreds of languages (here "2221"). While for most of those languages that's indeed the correct label, some use non-Arabic (or Eastern Arabic) numerals and thus different labels for that year, including Latin, Farsi, Bengali and Nepali, among others. I have discussed the issue with PokestarFan until he considered it "fixed" without changing any of the incorrect labels. What's the best way forward? For many of those languages I can't even tell what numerals they might use to refer to future years (literary Chinese?). Thus I'm tempted to simply revert all labels, and those that are definitely correct can then be individually re-added. Thoughts? Huon (talk) 22:46, 13 March 2017 (UTC)

How many of these did he create? I would revert/remove all wrong labels, and ask him to stop. 2017 (Q25290) could help to know when is correct to use Arabic numerals, as I assume it is an item reviewed by humans. Emijrp (talk) 23:10, 13 March 2017 (UTC)

Pasleim's PLbot seems to be addressing this already. Nonetheless, comparison of these year items with Q25290 also shows that they lack a description (though Q25290's could be better), calendar (also lacking in Q25290) and various other properties. Perhaps we ought to start by documenting, on project page, what a "good" year item would contain? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 23:37, 13 March 2017 (UTC)

What is the correct property to map an item in class non-metropolitan district (Q1187580) to an item in class district council (Q16690653) ?

The inverse relationship is straightforward, there seems to be consensus to express it as e.g.:

Redditch Borough Council (Q14978996)applies to jurisdiction (P1001)Redditch (Q21496675).

But, in the other direction, e.g. to map Redditch (Q21496675) to Redditch Borough Council (Q14978996), which one, two, or three of legislative body (P194), executive body (P208), or authority (P797) should apply?

For which role? As a general piece of advice, hard requirements are either listed, or they aren't that hard. --Elitre (WMF) (talk) 13:02, 13 March 2017 (UTC)

@Jura1: If there are good candidates with knowledge of Wikidata and Commons I will put my weight behind such a candidate. However I don't think this is a hard requirement. I wasn't a contributor to Wikipedia either when I started 5 years ago but I think I managed to get into things fairly quickly ;-) Besides that: the more good people from here apply the higher the chance that we'll find someone fitting with Wikidata knowledge. --Lydia Pintscher (WMDE) (talk) 15:11, 13 March 2017 (UTC)

• @Whatamidoing (WMF), Lydia Pintscher (WMDE): I wouldn't be in the frame for any of the jobs, but it does seem strange to publish these openings without (as far as I can see) any hint of the salary, or even the salary range. Is this normal for WMF? In terms of real pounds and euros, how much are you thinking of offering? Jheald (talk) 23:39, 13 March 2017 (UTC)
  • Jura, I'm not on the hiring committee, so I will tell you what I think plainly: If you (any of you) are a Wikimedian, and if you think that you would be good at this work, then you should apply. Please. Do not let unimportant factors like age (MediaWiki's API was written by a 16 year old), location (we have people all over the world), or formal education (your accomplishments matter more than a diploma) prevent you from applying. Do not even let "the requirements" stop you. I want the hiring committee to be choosing from among a hundred good candidates, and to have a hundred application letters that show them a hundred important skills that they'd never thought of.
    IMO the ideal candidate will already be familiar with Wikidata; if not, however, then we will have to teach that person about Wikidata promptly. I think that's achievable, and I hope that several of you will be thinking about what you want this person to learn first.
    Jheald, salary and benefits depend (heavily) upon your location. In general, I have the impression that community liaisons get paid "middle class" amounts (middle class in whatever your country is), and that product managers get paid a little more than CLs. Whatamidoing (WMF) (talk) 23:56, 13 March 2017 (UTC)
• From a Wikidata perspective, one might not want devs from Wikidata apply, as otherwise Wikidata development might be taken back ;)
  Still I think it's a key factor that persons active on this understand how Wikidata works and have some personal experience with it. There is much to be gained from these two parts of Wikimedia functioning together and avoiding redundancy.

Took me a big of digging, but I think I found it. We use CLDR. The list of languages is at https://github.com/wikimedia/mediawiki-extensions-cldr/blob/master/CldrNames/CldrNamesEn.php . Upstream is missing some languages, some of them are at https://github.com/wikimedia/mediawiki-extensions-cldr/blob/master/LocalNames/LocalNamesEn.php

So what we probably need is a list of valid Wikidata language codes (where can I find that one?) and compare each of them with both files and report the missing language codes.

This project is an ambitious next step in the GLAM programme being developed in Brazil: the goal now is to scaling up initiatives, with a digitalisation programme in one of the largest museums of the University of São Paulo, the Museu of Geosciences of the Institute of Geosciences.

The idea is to create new contributions here, and use the photos to illustrate entries.

I notice that SIC code (P3242) has a regular expression of digits between 1-4 characters. This list from Companies House has many examples of 5 digit codes. Should the regex be updated?

It might also be useful to update the description of that property to suggest more clearly when it should be used.

Pauljmackay (talk) 17:51, 15 March 2017 (UTC)

Checking this lookup suggests the codes could be much longer, e.g. 8 digits. Also I think my point about the UK codes is moot because the numbers are different, so it might be that there should be a new property to represent UK SIC codes? Pauljmackay (talk) 09:35, 16 March 2017 (UTC)

you can set "on hold" as the status. In general with templates go to the template page (such as Template:Property proposal in this case) to see documentation.

I am working on a list of people and find that many have an item but they are Wikipedia redirects. When we want to monitor the number of articles, they should not count. How does this work? Are redirects ok ? Thanks, GerardM (talk) 08:26, 16 March 2017 (UTC)

Hi @GerardM: At the moment I think the information that something is a redirect is held only in the traditional MediaWiki databases, not in Wikidata.

So there are basically two options to access it: either write a bot/scraper, or use a tool like m:PetScan/en -- on its Page Properties tab, PetScan I think lets you filter a list for pages that are redirects.

A further thing to keep in mind is that there are different reasons why a page might be a redirect. One is if the page has been moved, but the sitelink on Wikidata has never been changed. Alternatively, the page might be a redirect to a more general page, eg a "Bonnie" -> "Bonnie and Clyde" redirect. On several wikis redirects in this latter class can be marked with a Template:Soft redirect with Wikidata item (Q16956589) template -- which you can also filter for on PetScan. However, this is far from systematically populated as yet.

As an aside, IMO it would be a good thing if known sitelinks to redirects were marked as such, eg with a badge, on their Wikidata pages (though it would need to be a bot job or a system job to keep this up to date). IMO also, when a sitelink is to a "Bonnie" redirect, this should be indicated to users in the WP page sidebar. Sitelinks to rename-redirects should of course be updated. (Again, perhaps a bot job or a system job). Jheald (talk) 15:41, 16 March 2017 (UTC)

@Jheald: With this scritp: mw.loader.load( '//www.wikidata.org/w/index.php?title=User:Matěj_Suchánek/checkSitelinks.js&action=raw&ctype=text/javascript' ); you can check the status of every sitelink of an item. It check if is a redirect, a disambiguation or if the page is deleted. Sometime it's necessary reload the page. --ValterVB (talk) 18:01, 16 March 2017 (UTC)

• location of creation (P1071) requires that the item is an instance of a subclass of artificial physical object (Q8205328). Armor of Emperor Ferdinand I (Q28790437) is an instance of plate armor (Q3391846) which is not a subclass of artificial physical object (Q8205328).
• collection (P195) requires that the item is an instance of a subclass of item of collection or exhibition (Q18593264). Armor of Emperor Ferdinand I (Q28790437) is an instance of plate armor (Q3391846) which is not a subclass of item of collection or exhibition (Q18593264).
• place of publication (P291) requires that the item is an instance of Legendäre Reisen im Mittelalter (Q3331189). The Academy of Armory (Q28873311) is however an instance of editing (Q397239).

Oh your argument is about the editions, not the citation.

Again this is a situation of separating the intellectual concept/literary work from the edition(s) (similar discussion above). There will be an item for the concept/literary work, and an item for each edition. It is the editions that have the "published in" component. One does have to consider how the first presentation can be represented to its first appearance.

Here's Succu's answer, since reverted by another editor. It seems that he won't take this seriously. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 09:08, 16 March 2017 (UTC)

@billinghurst: For a republication in a new journal, you have a new set of properties like published in (P1433), issue (P433), publication date (P577), page(s) (P304), DOI (P356) and volume (P478). Then all usual identifiers will be doubled. Do you really want to handle all these properties in one item ? Just imagine the code you need to extract only the data of the original article or of the republication in WP for example: with your system you have to o through all statements and values and retrieve corresponding data according to the qualifiers. Just a nightmare. Two items is a little work at the begining but it is simpler to use later because the extracting code is more easy to write and to modify. Snipre (talk) 18:27, 15 March 2017 (UTC)

Even if there is only one edition, the page number(s) and volume belong as qualifiers. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:22, 15 March 2017 (UTC)

Why, Mr. Mabbett? --Succu (talk) 23:01, 15 March 2017 (UTC)

Because he is correct and you are not. Thanks, GerardM (talk) 05:37, 16 March 2017 (UTC)

It seems clear from the above that, with the exception of only one editor, who has offered no meaningful explanation, that page(s) (P304) and volume (P478) should be qualifiers of published in (P1433). Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:23, 17 March 2017 (UTC)

Actually, I am counting three versus two. If I add myself (I would tend to side with Succu and Snipre, but don't care all that much), this would be three versus three. This seems a ridiculously low number for an issue that so many isers have to deal with. - Brya (talk) 05:08, 18 March 2017 (UTC)

At the moment we have 954.224 items with published in (P1433). 599.476 items use volume (P478) as a property. 12.406 items use volume (P478) as a quaifier. Looks like this usage was introduced for the handling of ruwikisource. --Succu (talk) 10:56, 18 March 2017 (UTC)

OK, thanks. --Edgars2007 (talk) 07:15, 14 March 2017 (UTC)

It looks like things are good at the moment. We'll keep an eye on it though. --Lydia Pintscher (WMDE) (talk) 13:13, 18 March 2017 (UTC)

dmoz.org has announced that it is shutting down, with immediate effect, but the site remains up for the time being, and RDF dumps of the core data are still available. The material is available under this license. I believe it contains lots of data that is of potential interest to the free data movement, and might well qualify as a new Wikimedia project or Wikidata subproject. Is the data there of any use here? -- The Anome (talk) 11:12, 16 March 2017 (UTC)

@The Anome: There was discussion on this two weeks ago which came to little consensus except to adjust the existing Curlie ID (P998) formatter URL (P1630) (or add a third-party formatter URL (P3303)) to point to the Internet Archive. I'm sure few people will have objections to importing the rest of the database, assuming that the appropriate disambiguation can be done. Mahir256 (talk) 22:45, 16 March 2017 (UTC)

Thanks. I'm glad people are working on this. Thank goodness for the Internet Archive. -- The Anome (talk) 08:39, 17 March 2017 (UTC)

Update: it looks like Archive Team are also aware of this: [9], [10] -- The Anome (talk) 08:43, 17 March 2017 (UTC)

@The Anome, Mahir256: anyway, I nominated that property for deletion. --Liuxinyu970226 (talk) 10:47, 17 March 2017 (UTC)

@Liuxinyu970226, Mahir256: I've just stated my opposition to deletion in that PfD. Thanks for bringing it to attention here. -- The Anome (talk) 11:04, 17 March 2017 (UTC)

@The Anome: Please don't think that your efforts are inappropriate or unappreciated but did you see that I posted the above thread, posted to m:talk:Interwiki links, changed w:en:Template:DMOZ, remarked on Phabricator and Gerrit about removing DMOZ, commented on m:Wikinexus, emailed Jason at Archive Team, posted the thread on Slashdot, etc.? I don't mean to be rude but it seems like you did not really do any due diligence to figure out what the community is already doing before nominating this for deletion or even posting this thread. —Justin (koavf)❤T☮C☺M☯ 18:36, 17 March 2017 (UTC)

Embarrassing lack of due diligence on my part: @Liuxinyu970226: you proposed deletion... Excuse me for being so hasty. —Justin (koavf)❤T☮C☺M☯ 18:40, 17 March 2017 (UTC)

@Koavf: Ouch. You are criticizing the wrong target here: I'm actively advocating for the property to be kept, and for the data itself to be mirrored here to keep it preserved for posterity, just in case. We're working on the same side here. Thank you for your work elsewhere on this issue: it's great work that benefits the community. -- The Anome (talk) 07:51, 18 March 2017 (UTC)

@The Anome: Agreed--I apologize. That's why I made my second edit rapidly after the first. Thank you. —Justin (koavf)❤T☮C☺M☯ 16:30, 18 March 2017 (UTC)

Self-explanatory. PokestarFan (talk) (My Contribs) 01:12, 17 March 2017 (UTC)

I would have said the following. But it does not seem to work as expected, indeed... Syced (talk) 08:27, 17 March 2017 (UTC)

SELECT ?item
WHERE
{
	MINUS{
      ?item wdt:P31 ?type.
    }
}

?item needs some definition first (as it doesn't make sense to subtract something we don't know). Also, missing instance of (P31) is ok if there is subclass of (P279) already:

SELECT ?item WHERE {
  ?item wikibase:sitelinks [] .
  MINUS { ?item (wdt:P31|wdt:P279) [] } .
} LIMIT 1000

Try it!

• There is a non-WDQS version at Wikidata:Database reports/top missing properties by number of sitelinks/P31.
  --- Jura 09:46, 18 March 2017 (UTC)

Hoi, I noticed that the number of items with no statement is less than 10%. This is quite an achievement given that many items are added all the time. Thanks, GerardM (talk) 09:12, 17 March 2017 (UTC)

Next level is to group these by date of creation - I think a large part of that 10% is still from the "great mass 2013 upload drive". Jane023 (talk) 10:50, 17 March 2017 (UTC)

Per this data, we ended 2013 with id around Q15500000. This query says there are ~1,226,751 items without statements created before 2014. (1,226,751 / 2,487,761) × 100% = 49.3% (ie. almost half). Matěj Suchánek (talk) 11:06, 17 March 2017 (UTC)

Interesting! I have fixed enough of these to think that this difficult group of zero statement items are probably concepts that don't lend themselves to common P31 choices. Something like trending topics of some sort, or historical names of art movements for example. Jane023 (talk) 18:40, 17 March 2017 (UTC)

• Wikidata:Database reports/without claims by site includes lists for some wikis with recent items without statements ("items (recent)"). You could visit items there and add quality ratings. ;)

This section was archived on a request by: Matěj Suchánek (talk) 14:06, 24 March 2017 (UTC)

Wikidata:Item quality is currently fairly vague about how to measure the quality induced by sitelinks:

• (A): All appropriate sitelinks to corresponding Wikimedia projects
• (B): Most appropriate sitelinks to corresponding Wikimedia projects
• (C): Some sitelinks to corresponding Wikimedia projects
• (D): At least one sitelink (if applicable)
• (E): everything else.

There are probably at least two ways of measuring this:

• 1. In a relative way: does the item include sitelinks to all articles Wikipedias have on the same concept. If there are 10 sitelinks on the item and 1 sitelink on some duplicate item, this should be fine for (B)/(C)/(D)/(E). Assessing this would require spot checking for duplicates.
• 2. In an absolute way: does the item include sitelinks to all of the some 500 WMF sites we could link. If there are 10 sitelinks on the item and 1 sitelink on some duplicate item, this might only be fine for (D)/(E) and maybe (C). An automated calculation can assess this (WDQS has a simplified way to check it).

The relative way (1) measures something Wikidata contributors build and can fix, the absolute way (2) is just a measurement about a gap in one or the other Wikipedia. What do you think?
--- Jura 15:26, 12 March 2017 (UTC)

I thinkt the relative way is better, because otherwise you will never get class (A) items. You can't force small wikipedias to create a page about a person that is totally not relevant for their language, like a local rapper. Q.Zanden questions? 16:43, 12 March 2017 (UTC)

Wikidata:Item quality already states this in a "relative" way. To me, the "absolute" proposal is a nonstarter. It just doesn't make any sense. This conversation would be better held on Wikidata talk:Item quality where we can discuss the specific language to include in the criteria. All are welcome to join us there where we are addressing all sorts of questions like this one. --EpochFail (talk) 13:37, 15 March 2017 (UTC)

This discussion about sitelinks as a measure of quality is silly. There are lots of quality items that do not have any sitelinks at all, because they are closely related to something that does, but they have a different purpose on Wikidata - just look at all the "trees" vs "fruits of those trees" vs "seeds of those trees" etc. A typical Wikipedia article would just bundle all those concepts together, which is fine. Jane023 (talk) 15:58, 16 March 2017 (UTC)

Slightly off-topic, is there any publicly available tool by Wikimedia that can be used to measure the (relative/absolute) quality of individual items by the above definition, i.e., the input to the tool is item number and the output is its quality? Jsamwrites (talk) 12:39, 18 March 2017 (UTC)

No. That is what we are trying to get to with the above. --Lydia Pintscher (WMDE) (talk) 13:12, 18 March 2017 (UTC)

What is it that you are trying to achieve. It escapes me and arguments are made for another approach but it does not get attention. Neither is there any response to the arguments against this approach. Thanks, GerardM (talk) 09:07, 19 March 2017 (UTC)

Silly or not, I don't think it's entirely clear what the item quality criteria currently state, especially as actually checking for duplicates of the same concept doesn't seem to be an obvious thing to do. Some seem to be insist to do things in a Wikipedia way .. maybe we should follow the suggestion made earlier and attempt to allocate Wikidata development resources to more important issues.
--- Jura 08:56, 19 March 2017 (UTC)

The current proposal for quality is imho wrong. Quality is in the consistency of the data and in the linking to sources. A source may be a Wikipedia but for an author for instance a link to VIAF is more relevant; it establishes an identify in the international libraries. Data for an item like an author is associated with categories; the data the categories stand for should be included in Wikidata. Wikidata holds an edge over a Wikipedia when it knows about more articles that should be in the category.

When specific data on an item can be qualified; the qualifications are an integral part of the quality involved. Consequently it is great to know that a person was a ruler for a specific kingdom or sultanate, knowing dates and predecessor and successor make for great quality.

It is important to remember how young and incomplete Wikidata is. Things are improving rapidly but the relevance is mostly in the data itself. When language is considered, the fact that we hold the complete structure of Chinese places and their administrative entities makes it of high quality. The fact that we do not have English labels is hardly relevant. Collaboration on maintaining this data is much more relevant. When we think that language support is vital in assessing quality, it follows that attention is given to the usability of other languages. Showing a Q-number when a label is missing is something that needs urgent remediation. There is always at least one label.

The current approach to "quality" is one where single items are considered in isolation. It is much better to consider quality as a function of "set theory". It is more important to consider quality as one of connectedness to other items and sources. Quality can be expressed in the completeness of statements. Arguably when a Wikipedia article has Wikilinks including red links, Wikidata could have an associated statement. Thanks, GerardM (talk) 06:44, 13 March 2017 (UTC)

One thing that occurred to me was that a tool might be quite interesting that determined how many of the bluelinks in the first paragraph of a Wikipedia article were accounted for (and which were not) by statements on the corresponding Wikidata item.

Are there particular types of relationships that aren't yet being well captured? And are there items where the proportion is particularly low? This I think might be interesting to look at. Jheald (talk) 09:39, 13 March 2017 (UTC)

Yes I am inclined to agree with this. The trick is identifying the links you are talking about - I assume "instance of" and maybe "from xxx country", but maybe also more specific things regarding that article's "claim to fame" on that specific language Wikipedia. Jane023 (talk) 16:01, 16 March 2017 (UTC)

There is much data in categories that could be harvested on a regular basis. They reflect data as "educated at" "faculty at" etc. For many categories there are definitions in place (in Wikidata) that can be used for automation. When this is done for all Wikipedias it would improve Wikidata over the quality of single categories, Thanks, GerardM (talk) 16:16, 16 March 2017 (UTC)

Wikidata would be better served with more wiki links and red links. We could do a better job capturing data from categories; there are two obvious strategies and the easiest is to cooperate with the good people of DBpedia. Thanks, GerardM (talk) 14:48, 13 March 2017 (UTC)
