A common use case is to work with variable bindings, i.e., results sets of queries, in precisely the same way one does with SA. Even better, an ORM-like solution that binds to results sets or "RDF objects". You can, of course, just write rdflib code, but for anything beyond the most trivial usages, the rdflib API is very primitive.

I never heard of that. The SPARQL protocol is *super* trivial, intentionally, and a client or server shouldn't be more than few lines of Python. > I hacked it about for personal use as a Pylons controller action but > it's not much use unless you have a populated triple store to point > it at and some means of educating users about posing SPARQL queries. One obvious thing to do beyond the protocol spec is support for graph update; i.e., supporting a method to add, modify and delete triples and graphs. I think I included a pointer to ActiveRDF last post; but, if not: http://activerdf.org/.
