# Simple Knowledge Organisation System (SKOS) Primer
semweb @ 26 February 2008
Thank you to Tom Morris for pointing out that a SKOS primer is in Working Draft.
The SKOS Primer is indeed available now in W3C Working Draft Format. There has also been an update to the SKOS Reference Document recently (also currently in W3C Working Draft Format).
I am pointing this out here for two reasons:
- I used the SKOS format for my undergraduate project to link tags together in a meaningful way
- OpenLink Data Spaces (ODS) also uses SKOS (Documentation of ODS with SKOS is available)
Briefly, what is SKOS?
SKOS is a dialect/vocabulary of RDF to build thesauri and taxonomies which are also known as “concept schemes”. With SKOS you can build structures of terminologies using relationships such as “narrower”, “broader”, “prefLabel” (for a preferred label) and “altLabel” for an alternative label. Its a very useful format, and highly recommended.
