Hi, I am starting to experiment with D2RQ, and I created an example very similar to the one in the D2RQ-Jena walkthrough. When I do listStatements() with no arguments, I get these triples out of my MySQL database:
[http://localhost:2020/vocab/resource/example_age, http://www.w3.org/2000/01/rdf-schema#label, "example age"] [http://localhost:2020/vocab/resource/example_age, http://www.w3.org/1999/02/22-rdf-syntax-ns#type, http://www.w3.org/1999/02/22-rdf-syntax-ns#Property] [http://localhost:2020/vocab/resource/example, http://www.w3.org/2000/01/rdf-schema#label, "example"] [http://localhost:2020/vocab/resource/example, http://www.w3.org/1999/02/22-rdf-syntax-ns#type, http://www.w3.org/2000/01/rdf-schema#Class] [http://localhost:2020/vocab/resource/example_id, http://www.w3.org/2000/01/rdf-schema#label, "example id"] [http://localhost:2020/vocab/resource/example_id, http://www.w3.org/1999/02/22-rdf-syntax-ns#type, http://www.w3.org/1999/02/22-rdf-syntax-ns#Property] [http://localhost:2020/vocab/resource/example_name, http://www.w3.org/2000/01/rdf-schema#label, "example name"] [http://localhost:2020/vocab/resource/example_name, http://www.w3.org/1999/02/22-rdf-syntax-ns#type, http://www.w3.org/1999/02/22-rdf-syntax-ns#Property] [http://www.w3.org/2000/01/rdf-schema#label, http://www.w3.org/1999/02/22-rdf-syntax-ns#type, http://www.w3.org/1999/02/22-rdf-syntax-ns#Property] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/1, http://localhost:2020/vocab/resource/example_age, "23"^^http://www.w3.org/2001/XMLSchema#int] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/1, http://localhost:2020/vocab/resource/example_name, "Timmy Mellowman"] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/1, http://localhost:2020/vocab/resource/example_id, "1"^^http://www.w3.org/2001/XMLSchema#int] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/1, http://www.w3.org/2000/01/rdf-schema#label, "example #1"] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/1, http://www.w3.org/1999/02/22-rdf-syntax-ns#type, http://localhost:2020/vocab/resource/example] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/2, http://localhost:2020/vocab/resource/example_age, "21"^^http://www.w3.org/2001/XMLSchema#int] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/2, http://localhost:2020/vocab/resource/example_name, "Sandy Smith"] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/2, http://localhost:2020/vocab/resource/example_id, "2"^^http://www.w3.org/2001/XMLSchema#int] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/2, http://www.w3.org/2000/01/rdf-schema#label, "example #2"] [file:///homes/elenius/projects/vitis/svn/kms/onistt_mapping.ttl#example/2, http://www.w3.org/1999/02/22-rdf-syntax-ns#type, http://localhost:2020/vocab/resource/example] (The mapping file was generated with the generate-mapping tool and left alone). However, when I try listStatements(null, RDF.type, "http://localhost:2020/vocab/resource/example";); I get nothing. There should be 3 matching triples as far as I can tell. Another problem I had was that concurrent.jar was missing (problem solved by downloading it, but I thought you'd like to know).
