Yes, thanks, it rings now a bell :-) Indeed, PSPARQL exactly provides the solution you're looking for. The mapping can then be reduced to a SPARQL construct. Regarding implementation, one is available at http://cesare.inrialpes.fr/psparql/engine.html Note also that these features are on the wishlist of SPARQL2 ... so we are not speculating saying it will happen very soon in all SPARQL end-points!
