I'm not sure you should be too hamstrung by what is and isn't in the RDF
data model when creating an efficient way of storing/modelling RDF.  The
constraints of RDF can be applied on top of a much more efficient model.
This means most of the time, I think, creating a simpler model not a more
complicated one like creating a surrogate key from the s,p,o or making URI
Refs, bnodes and literals all the same type and making triples/statements
out of that.
