OK so far...

I don't understand what that means. What is the content of a graph? But in any case, doesnt that directly contradict the previous sentence? 

But whatever, it seems very odd for TimBL to advocate that an IRI not denote a resource. Are you *sure* you have this right?

Right, that is what the term was defined to mean in the paper which introduced the terminology in the first place.

No, that simply does not make sense. Graphs do not have contents and do not interact RESTfully or otherwise. Graphs are mathematical abstractions, remember? An RDF graph is a *set* of triples.... 

Maybe if you can say what you mean using the terminology we have all agreed upon, I might be able to figure out what you are saying.

I have included in the agenda some discussion topics that came up in recent telecons, plus the email of Andy on TriG examples.  I suggest we also have a meta-discussion on what our options are for getting consensus.
