Announcement | NKOS Application Profile | KOS Registries and Standards | NKOS Workshops | Archived early efforts
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, New Applications of Knowledge Organization Systems: introduction to a special issue.

3. NISO TR-06-2017, Issues in Vocabulary Management
Baltimore, MD - September 25, 2017 - The National Information Standards Organization (NISO) announces the publication of a new Technical Report, NISO TR-06-2017, Issues in Vocabulary Management. This document is one outcome of the NISO Bibliographic Roadmap Development Project, which was conducted in 2013-14 with funding from the Andrew W. Mellon Foundation. The technical report builds upon the work outlined in the 2014 project summary report Roadmap for the Future of Bibliographic Exchange by discussing policies supporting vocabulary use and reuse, documentation for vocabularies, and requirements for the preservation of RDF vocabularies.

NKOS Dublin Core Application Profile
NKOS Dublin Core Application Profile (version 0.2) is released 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.

NISO TR-06-2017, Issues in Vocabulary Management
Baltimore, MD - September 25, 2017 - The National Information Standards Organization (NISO) announces the publication of a new Technical Report, NISO TR-06-2017, Issues in Vocabulary Management.
- Special Issue on Networked Knowledge Organization Systems (NKOS) is published in the International Journal on Digital Libraries by Springer.
This special issue of the International Journal of Digital Libraries evolved from the 13th Networked Knowledge Organization Systems (NKOS) workshop held at the joint Digital Libraries conference 2014 in London. The focus of the workshop was ‘Mapping between Linked Data vocabularies of KOS’ and ‘Meaningful Concept Display and Meaningful Visualization of KOS’. The issue presents six papers on the general theme on both conceptual aspects and technical implementation of NKOS. We dedicate this special issue to our long-term colleague and friend Johan De Smedt who died in June 2015 while we were editing the special issue.
