[redland-dev] bug in rasqal

[Pierre-Antoine Champin]

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
