Dear Bryan, I tried with the exact data and SPARQL and SPARQL* queries which another user Jyoti mentions. The service description shows the following XML content, which I think are in accordance wiki. Please correct me if I am wrong: <rdf:RDF><rdf:Description rdf:nodeID="service"><rdf:type rdf:resource=" http://www.w3.org/ns/sparql-service-description#Service"/><endpoint
