Hello everybody! I was trying to execute a simple SPARQL query through the web interface (http://localhost:8080/fedora/risearch). I created 3 objects: Demo:2, Demo:3 and Demo:4. Demo:2 contains this RELS-EXT Datastream: <rdf:RDF xmlns:fedora="info:fedora/fedora-system:def/relations-external#" xmlns:myns="http://www.nsdl.org/ontologies/relationships#"; xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#";> <rdf:Description rdf:about="info:fedora/Demo:2"> <fedora:hasConstituent rdf:resource="info:fedora/Demo:3"> </fedora:hasConstituent> <fedora:hasConstituent rdf:resource="info:fedora/Demo:4"> </fedora:hasConstituent> </rdf:Description> </rdf:RDF>
The object Demo:3 has this RELS_EXT datastream: <rdf:RDF xmlns:dc="http://purl.org/dc/elements/1.1/"; xmlns:demoOntology="info:fedora/Demo:1#" xmlns:fedora="info:fedora/fedora- system:def/relations-external#" xmlns:j.0="http://www.dcs.shef.ac.uk/~ajay/image#"; xmlns:j.1="http://www.dcs.shef.ac.uk/~ajay/image/annotation#"; xmlns:myns="http://www.nsdl.org/ontologies/relationships#"; xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#";> <rdf:Description rdf:about="info:fedora/Demo:3"> <fedora:isConstituentOf rdf:resource="info:fedora/Demo:2"> </fedora:isConstituentOf> </rdf:Description> </rdf:RDF> The RELS-EXT datastream of Demo:4 has a datastream similar to that of Demo:3. If I execute this simple query: PREFIX fedora: <info:fedora/fedora-system:def/relations-external#> . SELECT ?a FROM <#ri> WHERE ?a <fedora:isConstituentOf> <info:fedora/Demo:2> I get this error: org.trippi.TrippiException: Encountered "." at line 1, column 69. Was expecting one of: "SELECT" ...
