sub property of: note

is in scheme
definition: Relates a resource (for example a concept) to a concept scheme in which it is included.

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

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

has broader
