An ontology of the Fediverse
– a Work in Progress.
SKOS vocabulary used with redaktor and skohub.io:
We try to summarize all terms used in ActivityPub, including official extensions and extensions specified by their diverse implementations.
We propose mappings and a way to extend ActivityStreams by famous well known knowledge concepts like wikidata.org, Library of Congress, schema.org etc.
The static pages in /docs published with skohub-vocabs are published for now at
The file Vocab.ttl is currently not builded.
It describes the roles of ActivityPub Actors (attributions) and Places in redaktor.
The vocabulary is also developed and maintained in the context of multiple sources,
e.g. https://wikidata.org, https://themoviedb.org or https://id.loc.gov/vocabulary/relators
