Re: Non-PK tables, blank nodes, and leanness

This is a non lean RDF graph and per the RDF semantics, they are equivalent. 

Gotta love the RDF semantics. 

So, even though they are equivalent per RDF semantics, we still maintain the cardinality. But if we query in SPARQL, we get two different things. Therefore, there is a mismatch between the semantics of SPARQL and RDF. Interesting, eh?
