Well your timing is very fortunate, ss of the end of last week the query results can be serialized as both JSON and SPARQL XML and the query/result APIs have changed (hopefully this will the final method signature) see: http://copia.ogbuji.net/blog/2006-06-23/rdf_query_apis_for_rdflib > > My plan is to work with JSON and SPARQL XML results serialization > (according to the spec.) during the next couple of weeks, and if > possible, I would like to integrate this with rdflib.

With regards to graph provenance tracking and garbage collection you might be interested in Michel Pelletier's development branch (not yet merged) which includes a framework for registering listeners to graph modfication: http://rdflib.net/pipermail/dev/2006-May/000010.html _______________________________________________ Dev mailing list [email protected] http://rdflib.net/mailman/listinfo/dev
