definition
A statement or formal explanation of the meaning of a concept.
is in scheme
Relates a resource (for example a concept) to a concept scheme in which it is included.
preferred label
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.
The range of skos:prefLabel is the class of RDF plain literals.
skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
The preferred lexical label for a resource, in a given language.
has broader
Broader concepts are typically rendered as parents in a concept hierarchy (tree).
Relates a concept to a concept that is more general in meaning.
has exact match
skos:exactMatch is disjoint with each of the properties skos:broadMatch and skos:relatedMatch.
skos:exactMatch is used to link two concepts, indicating a high degree of confidence that the concepts can be used interchangeably across a wide range of information retrieval applications. skos:exactMatch is a transitive property, and is a sub-property of skos:closeMatch.
