OK, but that does not mean that this URI actually denotes that document in RDF. Maybe the semantics of the fourth field in a quad store is different from that of fields in an RDF triple. (In fact, I think we are goingto *have* to assume it is different in order to give any kind of coherent semantics for quad stores.) The acid test would be whether you use this URI *inside an RDF triple* with this 'document provenance' meaning.
