Supertype and Subtype relationship

Like the type-instance relationship, this relationship is by its very nature binary, and like type-instance it is represented in both RDF and Topic Maps using a special vocabulary external to the model itself. In RDF, that A is a subclass of B is expressed with the statement (A rdfs:subclassOf B), whereas in Topic Maps it is expressed with the association iso:supertype-subtype(A : iso:subtype, B: iso:supertype).

RDFTM

Every statement of the form

(x rdfs:subclassOf y)

becomes an association of the form

iso:supertype-subtype(x : iso:subtype, y : iso:supertype)

TMRDF

Every association of the form

iso:supertype-subtype(x : iso:subtype, y : iso:supertype)

becomes a statement of the form

(x rdfs:subclassOf y)
