So will D2rq help me do this ? Sounds like you want a general-purpose rules engine that can transform between different ontologies. D2RQ doesn't include such a general-purpose rules engine. It can answer SPARQL queries against a single database by transforming them into SQL queries according to a (potentially complex) mapping.
