Hello all, Is it possible to configure VOS 6 to support rdfg:subGraphOf inferencing? Specifically such that a SPARQL query to a specific graph will return all triples in the named graph but also in subgraphs of the named graph that match the query?
Consider the following example triples that I have loaded into an instance of VOS 6.1.7: <http://example.org/test:a> <http://example.org/test_vocabulary:b> <http://example.org/test:c> <http://example.org/test:graph> . <http://example.org/test:d> <http://example.org/test_vocabulary:b> <http://example.org/test:e> <http://example.org/test:graph> . <http://example.org/test:f> <http://example.org/test_vocabulary:b> <http://example.org/test:g> <http://example.org/test:subgraph> . <http://example.org/test:h> <http://example.org/test_vocabulary:b> <http://example.org/test:i> <http://example.org/test:subgraph> . <http://example.org/test:subgraph> <http://www.w3.org/2004/03/trix/rdfg-1/subGraphOf> <http://example.org/test:graph> <http://example.org/test:graph> . When I execute the following query: SELECT * FROM <http://test.org/graph> WHERE { ?s <http://example.org/test_vocabulary:b> ?o . } The results returned are: ?s ?o <http://example.org/test:a> <http://example.org/test:c> <http://example.org/test:d> <http://example.org/test:e> However, I would also expect that <http://example.org/test:f> <http://example.org/test:g> . <http://example.org/test:h> <http://example.org/test:i> . should be in the results because it is asserted that <http://example.org/test:subgraph> is a subGraph of <http://example.org/test:graph>. How can I configure VOS 6 to achieve this?
