I’m using the Jena OWL reasoner with this ontology: http://www.mind-tap.net/kbswt/simple_no_inheritance.ttl
I want to get the named individuals that are instances of a modelica:BinaryExpression along with the rdfs:label of the class directly implemented by the named individual. I hope there is a SPARQL guru who can help identify what I need to do. If adding a Jena rule to the reasoner would help I have no problem going that route either. In essence: c subClassOf b b subClassOf a c rdfs:label “class c” b rdfs:label “class b” a rdfs:label “class a” x typeOf c x rdfs:label “instance x” I need to run a query to get: “instance x”, “class c” but my SPARQL gives me: “instance x”, “class c” “instance x”, “class b” “instance x”, “class a” I’ve tried some filter expressions but they wind up filtering out all the results. I was thinking there is some path modifier that might work but haven’t been successful going down that route either. My starter SPARQL: PREFIX modelica: <http://mind-tap.net/kbswt/modelica#> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX : <http://mind-tap.net/kbswt/simple_no_inheritance#> select distinct * { ?s rdfs:subClassOf modelica:BinaryExpression ; rdfs:label ?equationName . ?i a ?s. } ORDER BY ?i Thanks in advance, Chris
