Concept Types

It is possible to organize microthesauri entities in two hierarchies of types (concept types and relation types). It is also possible to link each concept to an open-ended list of concept types, each of which corresponds to some area of the thesaurus.

Extended Concept Types

Note: this information is a brief of https://www.w3.org/wiki/SkosCoreGuideToc/SectionExtending/ConceptTypes.

This section describes how to extend the skos:Concept class to create more specific classes of concept.
You can use the new class exactly as you would normally use skos:Concept.

Representing Fundamental Facets

An important use case for this type of extension is in the representation of fundamental facets within a concept scheme.

In a concept scheme ordered according to fundamental facets, each fundamental facet contains a homogeneous class of concepts, the members of which share characteristics that distinguish them from members of other classes.

So, for example, the Art & Architecture Thesaurus [ref] declares the following fundamental facets:

ASSOCIATED CONCEPTS
PHYSICAL ATTRIBUTES
STYLES AND PERIODS
AGENTS
ACTIVITIES
MATERIALS
OBJECTS

To represent fundamental facets in RDF, declare an extension of skos:Concept
