Hi Ivan,

Cool, I can agree with that as it opens up a whole can of worms, if you 
make access to Collections easier / custom, then why not the same for 
BlankNode, and so on and so forth, after implementing it's certainly 
easier just treating the store as a graph of triples, similar to N-Triples.

Will give some feedback specific to your RDFa Collections proposal under 
separate cover.

Many Thanks,

Nathan

In my personal opinion we should not spend energy on that one for now (regardless of the outcome of ISSUE-16), but flag it as a possible future item for RDF API
