That work indulgent question: Does that involve some sort of Query Pattern patterns? If I go to IMDB to resolve queries with certain predicates:, { ?m imdb:name ?movieName . ?m imdb:star ?starName } they will only answer if one of those is constrained:. [ wsdl:endpoint <imdb> ; saddle:answers [ saddle:pattern "{ ?m imdb:name ?movieName . ?m imdb:star ?starName }" ; saddle:mustBeConstrained (?movieName) ] ; saddle:answers [ saddle:pattern "{ ?m imdb:name ?movieName . ?m imdb:star ?starName }" ; saddle:mustBeConstrained (?starName) ] ; ] I've been curious about this for a bit so I'm wondering if Basian is solving this sort of problem.
