Section 5.1.3 defines how the base URI is determined - it's not an 
arbitrary choice.  RDF does not allow relative URIs.

http://www.w3.org/TR/rdf-concepts/#section-Graph-URIref

The complete solution is POST to container, get back a Location:, maybe 
a 301 (Moved Permanently), and PUT or POST to the location.  But it's a 
round trip and (arguably) an impractical nuisance.

If you want to use N-triples (no base URI), and the subject is the BPR, 
then you have to know the BPR URI before creating the N-Triples.
