Thesauri on the Semantic Web

W3C Semantic Web Best Practices and Deployment Working Group announces the publication of the following technical reports as first public Working Drafts:SKOS Core is a simple, flexible and extensible language for expressing the structure and content of concept schemes (thesauri, classification schemes, subject heading lists, taxonomies, terminologies, glossaries and other types of controlled vocabulary) in a machine-understandable form.

The SKOS Core Vocabulary is an application of the Resource Description Framework (RDF). Using RDF allows data to be linked to and/or merged with other data. In practice, this means that distributed sources of data can be meaningfully composed and integrated.

The 'SKOS Core Guide' is a guide to the recommended usage of the SKOS Core Vocabulary, for readers who already have a basic understanding of RDF concepts.

The 'SKOS Core Vocabulary Specification' gives a reference-style overview of the SKOS Core Vocabulary, and describes policies for ownership, naming, persistence and change management.

The 'Quick Guide to Publishing a Thesaurus on the Semantic Web' describes in brief how to express the content and structure of a thesaurus, and metadata about a thesaurus, in RDF, and gives some practical guidance for publication of RDF data.
