Dear A. Soroka, 
Thank you for the quick reply.

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.

Thanks
Jakob
