Frage

In Protégé 4.3 I have results with ObjectProperties (exactly as I need). But I need to implement it in my project so I use Jena in Eclipse and the result is different. How can I get object with ObjectProperties in Jena?

Lösung

I have no prob to write down some code as answer, but its hard to write it clear and easy to understand.

One more time: I ask how to get in jena sparql result like this object + object property + subject(s) [ C2-C4].

And the result is (this sample with 3 subjects)

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?c ?p1 ?C2 ?C3 ?C4
WHERE { 
    ?c rdfs:subClassOf ?r . 
    ?r rdf:type owl:Restriction . 
    ?r owl:onProperty ?p1 . 
    ?r owl:someValuesFrom ?i . 
    ?i rdf:type owl:Class . 
    ?i ?prop ?l . 
    ?l rdf:first ?C2 . 
    ?l rdf:rest ?m . 
    ?m rdf:first ?C3 . 
    ?m rdf:rest ?m2 . 
    ?m2 rdf:first ?C4 . 
    ?m2 rdf:rest rdf:nil .
    }
