Review by RDF-WG, See message from Manu

Guus to briefly review his comments on RDFa Primer. David and Charles to briefly review their comments on RDFa Core.

David's comments

Named Graphs

Issue: should/must the 4th slot be an IRI?

See thread starting with http://lists.w3.org/Archives/Public/public-rdf-wg/2011Nov/0116.html

Two alternative points of view (see minutes 30 Nov):

1. we are not in a position to constrain the type of the "4th slot"
2. we are standardizing graph identifiers, so they better be identifiers (= IRI)

Todo: list arguments in favor/against these positions (e.g. #1 breaks TriG).

Sandro wanted Pat's comment on scoping.

Pat's comments: "2c: if we allow bnodes in the 4th position, then please lets make a firm decision what their intended scope is going to be, and that they cannot also occur in other positions in the same graph store. But I vote to not allow bnodes in 4th position in any case."

IRI names for both graph containers and graphs?

Leave this ambiguous? See Pat's message: http://lists.w3.org/Archives/Public/public-rdf-wg/2011Dec/0189.html

• Are names for a graph (as opposed to a graph container) needed? Potential use case: signing a graph.
• Can we handle ambiguity of IRI names?

More test cases?
