Just to wrap this up ... for the time being ...

I just found this;


Which pretty much expresses my concerns, in particular;

"RDF is stuck right now in not having a standard way to indicate which
extensions/ontologies are being used."

My *hunch* is that dereferencable media types (i.e. media types as
URIs) which resolve to a declaration of (at least?) their axiomatic
triples, is what is needed to complete(*) the self-describability of
RDF.  But I've got a lot more reading to do ... 8-)

FWIW, there's work under way to try to bridge media types and URIs.

(*) we also need mandatory extensions within RDF, I believe
