Me too

> I'm not sure whether they actually want the "name" to denote the graph. They certainly want it to denote a "bundle", which indeed will /contain/ RDF triples, but may be distinct from an RDF graph (especially since "bundles" do not consist of triples in the abstract syntax). At least, it is the way I interpret it, and it is the way I would like it to be. It gives more flexibility as the graph IRI is not rigidly fixed to the exact set of triples providing in a particular RDF dataset. With this view, it is even less a problem that we do not tell them what the graph IRI denotes.

I am not sure this distinction will help, although that decision is certainly not ours (having my RDF WG hat on) but. theirs (well, ours if I put on my Proveance WG hat:-)

The abstract data model and its syntax is not really meant for large scale deployment per se. It is equivalent to the OWL 2 functional syntax. The 'real' deployment is in terms of the Prov-O, which is simply an OWL ontology, ie, in that world, a bundle is really a collection of triples.

That being said, you may be right if we consider that the group also intends to produce an XML encoding of the provenance statements. So if there is a name/URI, and I dereference it, what would I get? Although conneg might help here, so we may be fine.

But, again, I do not think we should get there too deeply. We have enough on our plate:-)
