Charter constraints

• WG charter expires 1 Feb 2013
• Extension in all likelihood only possible if by that time RDF Concepts, RDF Semantics and Trig (read: named-graph syntax proposal) are in LC
• What can we realistically achieve in the next three months?

Dataset semantics

Two main threads:

 http://lists.w3.org/Archives/Public/public-rdf-wg/2012Sep/0212.html
 http://lists.w3.org/Archives/Public/public-rdf-wg/2012Sep/0210.html

Minimal semantics proposal from Antoine:

 http://www.w3.org/2011/rdf-wg/wiki/TF-Graphs/Minimal-dataset-semantics

Alternative proposal by Peter:

 http://lists.w3.org/Archives/Public/public-rdf-wg/2012Sep/0151.html

Excerpt from this message:

1. No change to the semantics for RDF graphs.
2. Entailment between RDF datasets D1=<G1,N1> and D2=<G2,N2> is defined as
   • a) G1 entails G2
   • b) for each <n,g> in N2 there is some <n,g'> in N2 such that g' entails g, or if there is no such <n,g'> then the empty RDF graph entails g

Phrased slightly differently by Pat:

Does this block use cases?
