Hardly. Inheritance as a concept implies that we know the precise type of
the document (e.g. that the document was authored by a specific person).
Conveying this information via URI's, which is what RDF uses, of course, is
heavy enough to make for near equality with explicit metadata. And
rdf:aboutEachPrefix, on the other hand, is far to difficult to implement at
the moment. It only works within the one-world assumption, which is
generally difficult to maintain in the Web environment.
