Yes, if #3 provides pointers to #1 & #2.

Yes, certainly !

I think this applies to anything that references DBpedia but not created 
by the core project members. If you recall, there have been a number of 
DBpedia linksets (see the mailing list archives) from across the LOD 
community that we've loaded into the DBpedia instance, using distinct 
graph IRIs etc..

I only get demonstrably impatient when the message (easily perceived as 
a marketing message) gets out of sync with the actual deliverables.

Linked Data is about LINKs, so whenever there is talk of Linked Data 
there should be a LINK in place to materialize the value prop. of a 
given Linked Data Space. The LINK in question should really be a conduit 
to SPARQL endpoint, Data Set URLs etc., since value prop. imbibers are 
going to be varied -- naturally.

This is just about reference, no different to saying: LOD.

That's basically my point :-)
