Modern systems need to run in many different contexts like hardware and software platforms or environmental conditions. Additionally different customers might have slightly different requirements towards systems. Therefore software systems need to be ...

The worldwide use of the Internet and social networking has transformed the constraints of time and space in human interaction: we can now be heard at a massive scale unprecedented in human history. As a result, information and communication ...

Linked data provides methods for publishing and connecting structured data on the web using standard protocols and formats, namely HTTP, URIs, and RDF. Much like the web of documents, linked data resources continuously evolve over time, but for the most ...

Research on differencing and versioning in computer science, writing research, and scholarly editing are all concerned with the evolution of texts and documents through various drafts, versions, and changes between different stages. While the different ...

"What's new?" and "What has changed?" are questions users of Knowledge Organization Systems (KOS), such as thesauri or classifications, ask when a new version is published. Much more so, when a thesaurus existing since the 1990s has been completely ...

The parallel engineering of cyber-physical production systems (CPPSs), an important type of sCPS, needs the collaboration of several engineering disciplines, which use a wide range of heterogeneous tools and data sources. Systems engineers and process ...

While the Semantic Web currently can exhibit provenance information by using the W3C PROV standards, there is a “missing link” in connecting PROV to storing and querying for dynamic changes to RDF graphs using SPARQL. Solving this problem would be ...

The ability to access and query data stored in multiple versions is an important asset for many applications, such as Web graph analysis, collaborative editing platforms, data forensics, or correlation mining. The storage and retrieval of versioned data ...

By software vendors offering, via the cloud, software-as-a-service SaaS versions of traditionally on-premises application software, security risks associated with usage become more diversified. This can greatly increase the value associated with the ...

Many teams are now adopting shared repositories for their work. Such adoption is paradoxical, however, as past research has repeatedly shown major co-organizational barriers; teams cannot agree a common organizational scheme, making it difficult to ...

While the (Semantic) Web currently does have a way to exhibit static provenance information in the W3C PROV standards, the Web does not have a way to describe dynamic changes to data. While some provenance models and annotation techniques originally ...

In this paper, we explore the economics of free under perpetual licensing. In particular, we focus on two emerging software business models that involve a free component: feature-limited freemiumFLF and uniform seedingS. Under FLF, the firm offers the ...

End users with little formal programming background are creating software in many different forms, including spreadsheets, web macros, and web mashups. Web mashups are particularly popular because they are relatively easy to create, and because many ...

This paper presents a new content centric approach to provenance data tracking: Document DNA. We present the results and analysis of our exploratory study on the re-use and re-finding of content contained in digital documents. The study's results ...

Versioning file systems are widely used in modern computer systems as they provide system recovery and old data access functions by retaining previous file system snapshots. However, existing versioning file systems do not perform well with the emerging ...

There are currently no shared formalization of the output of diff algorithms, the so called deltas. From a theoretical point of view, without such a formalization it is difficult to compare the output of different algorithms. In more practical terms, ...

In this paper, we describe a storage scheme that allows the representation and management of the evolving hierarchical structure of a multi-version ontology. The proposed scheme is aimed at supporting ontology-based personalization and temporal access ...

It is commonly believed that piracy of information goods leads to lower profits, which translate to lower incentives to invest in innovation and eventually to lower-quality products. Manufacturers, policy makers, and researchers all claim that ...

A set of design patterns describing problems and solutions in multi-generation software systems is presented. A new generation of a system is seen when a software system goes through a quantum leap, or a major new release, or technology shift. A central ...
