A discussion of the design and implementation of an RDF API.
This is a vital concept: building additional semantics on top of simpler RDFModels.
First, it's probably worth sketching out a little class diagram. Note at the moment this is talking about TripleStores only; we come on to the properties that an RDF API should layer on top in a moment.
Todo: get the layering diagrams. Rip off shamelessly from layered filesystem papers for justification.
