Hmm, this is not really what I was getting at, as it includes lots of
issues about the relationship between RDF graphs and the real world.

I'm only interested in relationships between RDF graphs.  Which such
relationships are RDF relationships?  

My view is that the only such relationships are RDF entailment and RDFS
entailment.  Any agent that computes any other relationship between RDF
graphs is not doing RDF.  (Well, actually, I suppose that an agent could be
determining whether two RDF graphs RDF entail each other, which is
different from RDF entailment, but I think that you should be able to get
my drift.)
