=== SWAD-Europe (2002–2004) ===

SKOS as a distinct initiative began in the SWAD-Europe project, bringing together partners from both DESIRE, SOSIG (ILRT) and LIMBER (CCLRC) who had worked with earlier versions of the schema. It was developed in the Thesaurus Activity Work Package, in the Semantic Web Advanced Development for Europe (SWAD-Europe) project.<ref>{{cite web|url=http://www.w3.org/2001/sw/Europe/|title=Semantic Web Advanced Development for Europe (SWAD-Europe)|website=www.w3.org}}</ref> SWAD-Europe was funded by the [[European Community]], and part of the [[Information Society Technologies]] programme. The project was designed to support W3C's Semantic Web Activity through research, demonstrators and outreach efforts conducted by the five project partners, [[ERCIM]], the ILRT at [[Bristol University]], [[HP Labs]], [[CCLRC]] and Stilo. The first release of SKOS Core and SKOS Mapping were published at the end of 2003, along with other deliverables on RDF encoding of multilingual thesauri<ref>{{cite web|url=http://www.w3c.rl.ac.uk/SWAD/deliverables/8.3.html|title=SWAD-Europe Deliverable 8.3 : RDF Encoding of Multilingual Thesauri|publisher=|deadurl=yes|archiveurl=https://web.archive.org/web/20060616014639/http://www.w3c.rl.ac.uk/SWAD/deliverables/8.3.html|archivedate=2006-06-16|df=}}</ref> and thesaurus mapping.<ref>{{cite web|url=http://www.w3c.rl.ac.uk/SWAD/deliverables/8.4.html|title=SWAD-Europe Deliverable 8.4 : Inter-Thesaurus Mapping|publisher=|deadurl=yes|archiveurl=https://web.archive.org/web/20060430071751/http://www.w3c.rl.ac.uk/SWAD/deliverables/8.4.html|archivedate=2006-04-30|df=}}</ref>

The SKOS main published documents — the SKOS Core Guide,<ref>[http://www.w3.org/TR/swbp-skos-core-guide SKOS Core Guide] W3C Working Draft 2 November 2005</ref> the SKOS Core Vocabulary Specification,<ref>[http://www.w3.org/TR/swbp-skos-core-spec SKOS Core Vocabulary Specification] W3C Working Draft 2 November 2005</ref> and the Quick Guide to Publishing a Thesaurus on the Semantic Web<ref>[http://www.w3.org/TR/swbp-thesaurus-pubguide Quick Guide to Publishing a Thesaurus on the Semantic Web] W3C Working Draft 17 May 2005</ref> — were developed through the W3C Working Draft process. Principal editors of SKOS were Alistair Miles,<ref>{{cite web|url=http://purl.org/net/aliman|title=Alistair Miles|website=purl.org}}</ref> initially Dan Brickley, and Sean Bechhofer.

The Semantic Web Deployment Working Group,<ref>{{cite web|url=http://www.w3.org/2006/07/SWD/|title=W3C Semantic Web Deployment Working Group|website=www.w3.org}}</ref> chartered for two years (May 2006 – April 2008), has put in its charter to push SKOS forward on the [[W3C Recommendation]] track. The roadmap projected SKOS as a Candidate Recommendation by the end of 2007, and as a Proposed Recommendation in the first quarter of 2008. The main issues to solve were determining its precise scope of use, and its articulation with other RDF languages and standards used in libraries (such as [[Dublin Core]]).<ref>[http://isegserv.itd.rl.ac.uk/public/skos/press/dc2006/camera-ready-paper.pdf SKOS: Requirements for Standardization]{{dead link|date=March 2018 |bot=InternetArchiveBot |fix-attempted=yes }}.

*Some important vocabularies have been migrated into SKOS format and are available in the public ___domain, including [[EuroVoc]], [[AGROVOC]] and [[GEMET]]. [[Library of Congress Subject Headings]] (LCSH) also support the SKOS format.<ref>{{cite web|url=http://id.loc.gov/authorities/about.html|title=About the Library of Congress Authorities|publisher=|deadurl=yes|archiveurl=https://web.archive.org/web/20100103222746/http://id.loc.gov/authorities/about.html|archivedate=2010-01-03|df=}}</ref>

*SKOS has been used as the language for the thesauri used in the [[SWED Environmental Directory]]<ref>{{cite web|url=http://www.swed.org.uk/swed|title=Semantic Web Environmental Directory|publisher=}}</ref> developed in the SWAD-Europe project framework.

*A way to convert thesauri to SKOS,<ref>{{cite web|url=http://thesauri.cs.vu.nl/eswc06/|title=A Method to Convert Thesauri to SKOS|website=thesauri.cs.vu.nl}}</ref> with examples including the [[Medical Subject Headings|MeSH]] thesaurus, has been outlined by the [[Vrije Universiteit Amsterdam]].
