Suppose I have a graph: @prefix foo: <http://foo.bar/vocab/foo#> foo:Foo a owl:Class ; rdfs:label "The Foo concept"@en . foo:Bar a owl:Class ; rdfs:label "The Bar concept"@en ; foo:has_part foo:Foo . foo:has_part a owl:ObjectProperty ; When doing a standard DESCRIBE <http://foo.bar/vocab/foo#Foo> on the my Fuseki SPARQL endpoint, I get the answer foo:Foo rdf:type owl:Class . foo:Foo rdfs:label "The Foo concept"@en . but not foo:Bar foo:has_part foo:Foo . since only triples are returned where the <http://foo.bar/vocab/foo#Foo> resource is the subject (<res> ?p ?o) not where it is the object (?s ?p <res>) or predicate (?s <res> ?o) I could navigate to foo:Bar by inserting foo:part_of as a reverse relationship to foo:has_part but do would like to avoid these additional triples in the 70k triple data set. I hope my question became somewhat clearer.
