Re: members property in hierarchy

[iman]

Thanks a lot Rubin,
it did worked like you wrote below with *. the Name is a property which 
i have defined in my SNIK ontology. each worker has a name, which i want 
to get as well.

thanks again

Hi Iman,

One first thing to note about this query:

SELECT Distinct ?worker ?name
     WHERE
{
     ?z  rdfs:subClassOf  <http://imise/SNIK/Human_ressource>.

     ?y rdfs:subClassOf <http://imise/SNIK/Staff>.

     ?worker a ?y.

}
Not that ?z has no relation with ?worker or ?y at all.
This is probably not what you meant.
Also, the query seems incomplete; the above won't execute.
Where does ?name come from?

I think you mean something along the lines of:

SELECT DISTINCT ?worker
{
     ?y rdfs:subClassOf* <http://imise/SNIK/Staff>.
     ?worker a ?y.
}

Note the asterisk * after rdfs:subClassOf (this is a SPARQL 1.1 feature)
so that the class itself and deeper subclasses are also matched.

Best,

Ruben
