The problem

Representing temporal evolutions of concept schemes and their content. Versioning.

Relevant work

Focused on KOSs:

  • "A Metadata Registry from Vocabularies UP: The NSDL Registry Project". Diane I. Hillmann, Stuart A. Sutton, Jon Phipps, Ryan Laundry, Dublin Core 2006, has a discussion of versioning SKOS vocabularies on page 4.
  • Two blog posts by Pete Johnston: 1, 2
  • skos-history: Ontology and processing practices for versions of SKOS vocabularies (Project on GitHub)
  • Case study: "Leveraging SKOS to trace the overhaul of the STW Thesaurus for Economics" by Joachim Neubert, applying the skos-history methods (DC-2015 paper)

In more general context:

  • ISO 19135:2005 Geographic information -- Procedures for item registration
    • a generic model for registration (publication) of items in 'registers'
    • includes workflows for modification of registers, and identifies key parties involved in the registration process
    • formalized in a UML profile that is close to RDF

Previous discussions

Related Issues

  • Linking SKOS concepts to other representations of the same referent. See foaf:focus. Different versions of a concept have the same focus, either across different concept schemes, or across different versions of the "same" concept scheme.
