Hi,

I know this is an editor's draft in early stages and it's a bit early to comment on it. But I read something in it which I don't quite understand:

Under http://dvcs.w3.org/hg/rdf/raw-file/default/rdf-concepts/index.html#section-skolemization it says "This transformation does not change the meaning of an RDF graph, provided that the Skolem IRIs do not occur anywhere else."

Doesn't that contradict one of the basic RDF ideas that adding triples can never change the semantics of previously stated triples? At least that's how I always understood it.

And where else is a skolem IRI supposed to appear or not appear? In another graph somewhere on the Web? Do I have to fear now that someone on the Web might publish something that suddenly changes the meaning of the graph stated in my RDF file? And what would it be that they could do to accomplish this?

Thanks,
   Simon
