Re: members property in hierarchy

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
