example1.c is the simplest, example4.c is the most complete, testing
most of the api.

Single model - I've not completed writing the aggregated model stuff.

That depends on what you want to do.  The document boundaries will be
lost once you load them all into one graph (redland model).  If you
load them with the correct base URI, you may still have a
relationship between the document URI and the RDF triples inside it.

You might benefit from the use of Redland contexts, which I've just
discovered aren't in a full example yet.  There is, however, some
test code at the end of librdf/rdf_model.c that might help.
