Hi Nathan,

Thanks for putting together that very detailed description of the
various points related to this discussion. My thoughts below:

+1 for RDFGraph interface aligned w/ ECMA-262-v5.

+1 to method, not property.

I think the method should return a copy of the processor graph, in case
one wants to do something with it between multiple processing runs. If
we use a property, the property would change every time the parser runs.
I don't think that there is a big downside to that, so if there is a
compelling reason to use a property, we can do that. It also feels to me
like the implementation of the processor graph should be hidden so that
we could use named graphs behind-the-scenes as soon as we get them
(after RDF WG discusses how they should be implemented).

+1 to RDF Graph Store
-1 to RDF Triple Store - I don't think we need this concept, feels like
                         we're over-engineering the mental model.

+1 to this - although, I don't think there would be anyone against
getting this done and out there. :)

-1 to Triple Store, reasoning is above.
+1 to Graph Store in a note.
