now the query is actually executed, but a query like =


select distinct ?r ?reqProp1 where { { OPTIONAL { ?r =

<http://www.semanticdesktop.org/ontologies/2007/01/19/nie#url> ?reqProp1 . =

FILTER(bif:exists((select (1) where { ?r a [ =

<http://www.semanticdesktop.org/ontologies/2007/08/15/nao#userVisible> =

"true"^^<http://www.w3.org/2001/XMLSchema#boolean> ] . }))) . } }
