supporting the deployment in RDF/OWL of thesaurus (and similar) structured

The PORT TF manages the SKOS Core Vocabulary, an RDF
vocabulary for describing the basic structure and content of concept schemes
such as thesauri, classification schemes, subject heading lists, taxonomies,
'folksonomies', other types of controlled vocabulary, and also concept
schemes embedded in glossaries and terminologies. See the SKOS Core home page for a
full description and links to current information.
- A W3C Note on thesaurus and related techniques for the Semantic
- An RDF/OWL vocabulary for representing thesaurus structures within
long term goals
- Document strategies for representing Thesaurus-like content using
- Produce guidelines for transforming an existing thesaurus (or
classification system, or similar concept-based taxonomy) into an
RDF/OWL representation. Guidelines should describe strategies for
converting into an RDF representation of thesaurus-like structures, as
well as strategies for re-describing in RDF/OWL the content originally
conveyed in the Thesaurus.
- Provide links to tools, applications, papers on this topic.
- The WG should seek to avoid duplicating existing work, and should
provide links to existing efforts, encouraging feedback (via the firstname.lastname@example.org mailing
from implementors on the pros- and cons- of the approaches
- Encourage dialog between RDF and Semantic Web developers and members of
the digital library community
- Many existing researchers in the digital library community (including
Dublin Core and related) are using classification schemes and thesauri,
and are not yet familiar with the facilities offered by RDFS and OWL.
It is important to engage these communities rather than offer them
solutions couched in the language of RDFS and OWL. In particular,
concepts from the thesaurus world, such as 'facets' relate in
non-obvious ways to similar, but more formalised, mechanisms offered by
W3C's OWL technology.
