has exact match
sub property of: has close match
definition: 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.
comment: skos:exactMatch is disjoint with each of the properties skos:broadMatch and skos:relatedMatch.

has close match
sub property of: mappingRelation
definition: 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.

preferred label
sub property of: label
definition: The preferred lexical label for a resource, in a given language.
comment: skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
comment: The range of skos:prefLabel is the class of RDF plain literals.
comment: A resource has no more than one value of skos:prefLabel per language tag.

alternative label
sub property of: label
definition: An alternative lexical label for a resource.
comment: skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
comment: The range of skos:altLabel is the class of RDF plain literals.
