Concept
The preferred lexical label for a resource, in a given language.
skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
The range of skos:prefLabel is the class of RDF plain literals.
A resource has no more than one value of skos:prefLabel per language tag, and no more than one value of skos:prefLabel without language tag.

skos:closeMatch is used to link two concepts that are sufficiently similar that they can be used interchangeably in some information retrieval applications. In order to avoid the possibility of "compound errors" when combining mappings across more than two concept schemes, skos:closeMatch is not declared to be a transitive property.
