Simple Knowledge Organization System (SKOS) is a language designed to represent thesauri and other classification resources. It encodes these products in a systematised way using RDF to make their structures comparable and to facilitate interaction.
It is also vital that thesauri maintain currency. Like dictionaries, thesauri describe the changing world around them; thesaurus-creators work hard to ensure their products are up-to-date.
The UK Data Archive undertook a JISC-funded project from June 2012 to March 2013 to apply SKOS to our HASSET thesaurus. Applying SKOS to HASSET has meant that our thesaurus is more widely available and more usable.
More information is available on our SKOS-HASSET blog, via our SKOS-HASSET project webpages or from a webinar we broadcast on the activities and results of the project on 28 March 2013. The webinar's slides are also available.
