F.30 SKOS 

F.30.1Overview 

SKOS is an area of work developing specifications and standards to support the use of knowledge organization systems (KOS) such as thesauri, classification schemes, subject heading systems and taxonomies within the framework of the Semantic Web.

F.30.3 Key characteristics 

A natural language ontology that has a structure similar to a thesaurus. 

F.30.4 Relevant extracts 

Extracts from: https://www.w3.org/TR/skos-reference/

Extract 1 – Similar structure to thesauri, etc. 

Many knowledge organization systems, such as thesauri, taxonomies, classification schemes and subject heading systems, share a similar structure, and are used in similar applications. SKOS captures much of this similarity and makes it explicit, to enable data and technology sharing across diverse applications. 

Extract 2 – Higher order concepts 

9. Concept Collections 

9.1. Preamble 

SKOS concept collections are labeled and/or ordered groups of SKOS concepts. 

Collections are useful where a group of concepts shares something in common, and it is convenient to group them under a common label, or where some concepts can be placed in a meaningful order.
