SPARQL GSP vs BP

Looking at how the SPARQL Graph Store Protocol (GPS) and Basic Profile 
(BP) submission compare, the most obvious difference I see is the fact GPS 
primarily deals with "graphs" while BP deals with Basic Profile Resources 
and Containers.

So, I'd like to ask whether considering a BPR as a graph would, at least 
to some extend, provide some alignment between the two specs. I think two 
aspects need to be considered: 1) what URL is used, 2) what triples are 
returned.

Thoughts?
