NKOS is devoted to the discussion of the functional and data model for enabling knowledge organization systems/services (KOS), such as classification systems, thesauri, gazetteers, and ontologies, as networked interactive information services to support the description and retrieval of diverse information resources through the Internet.

Knowledge Organization Systems/Services (KOS) model the underlying semantic structure of a domain. Embodied as Web-based services, they can facilitate resource discovery and retrieval. They act as semantic road maps and make possible a common orientation by indexers and future users (whether human or machine). -- Douglas Tudhope, Traugott Koch (2004). New Applications of Knowledge Organization Systems: introduction to a special issue.

NKOS Dublin Core Application Profile (NKOS AP)

NKOS Dublin Core Application Profile (version 0.2) 2015-09

The DCMI/NKOS Task Group targets to develop a Dublin Core Application Profile for KOS resources based on the work the NKOS group members have already done during the last decade. The application profile will be further tested by professionals and researchers.
