The devil is in the “may” Technically it can be used broader but by convention/best-practise the “may” seems actually...”is typically only used for referencing to whole vocabs...”

If it is of any use: at KOOP, I use examples of rdfs:isDefinedBy to explain the notions of baseURI, owl:Ontology and namespace. URIs are "minted" in the graph where the corresponding resources are defined with a rdfs:isDefinedBy-statement with the graph as value. Next, the URIs can be reused elsewhere. Pseudo-authorative examples include rdfs, skos, dcterms, void and many, many others. -j On Friday, November 29, 2019 at 3:05:22 PM UTC+1, Irene Polikoff wrote: This is correct. If one looks at the spec defining this property, it says "indicates the resource defining the subject resource. As with rdfs:seeAlso, this property can be applied to any instance of rdfs:Resource and may have as its value any rdfs:Resource." However, it is also true that by convention this property is used to identify a graph that defines a given resource. I also have not seen it used in any other way. One could say that the de facto practice gave this property a more limited/targeted semantic than stated in the spec. It then becomes a matter of judgement whether to use it in a way that is different from this convention.

Technically is seems ok (rdfs:resource range) but I see only uses where the target is a complete ontology... Thx Michel Dr. ir. H.M.
