Unfortunately, a glaring hole in SPARQL is lack of add or update capability. Jena (http://jena.sourceforge.net), the framework sponsored by HP Labs, includes an implementation of a proposed update language for SPARQL - see http://jena.sourceforge.net/ARQ/update.html. The other major framework for RDF is Sesame (http://openrdf.org), and they appear to emphasize their own propietary language (SeRQL) that is considerably more powerful, but only supported by Sesame. All the same, semantic web technology is worth keeping an eye on, even if it is still in its infancy.

I believe many of these graph database / triple store packages support SPARQL..
