An rdfs:isDefinedBy relation associates Properties and Classes with the 
vocabulary in which they are defined.

An wdrs:describedby (equivalentPropertyOf xhv:describedBy and 
inversePropertyOf xhv:describes) relation associates Properties and 
Classes with a Vocabulary document (e.g., 
<http://schema.org/docs/schema_org_rdfa.html>) that is comprised of 
statements describing the aforementioned Properties and Classes.

Ideally, you want to use both relations due to the fact that an Ontology 
is one entity, a Document comprised of what constitutes an Ontology is 
another entity [1].

We use the pattern outlined above, across the board.

wdrs:describedby relations
