Hi, It seems to me that rasqal 0.9.15 is bugged with regard to FILTER embeded in an OPTIONAL pattern
see http://www.w3.org/TR/rdf-sparql-query/#OptionalAndConstraints the result with rasqal is result: [title=string("The Semantic Web"), price=string("23"^^<http://www.w3.org/2001/XMLSchema#integer>)] roqet: Query returned 1 results Seems that the FILTER is filtering at the "top level", not only the subresults of the optional pattern. NB: I could not test rasqal 0.9.16 (sorry about that), but the release note does not mention any bugfix related to filter, so I assume it is still there... regards Pierre-Antoine Champin
