sub property of: Transitive
definition: Relates a concept to a concept that is more general in meaning.

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

preferred label
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.
sub property of: label
definition: The preferred lexical label for a resource, in a given language.

has related
comment: skos:related is disjoint with skos:broaderTransitive
sub property of: semanticRelation
definition: Relates a concept to a concept with which there is an associative semantic relationship.
