Hi,
Is it possible to query the reachability of a resource from another?
For example, given the triples:

t1, cxn1, t2
t1, cxn2, t3
t2, cxn3, t4
t5, cnx4, t6


can i execute a query that says: 

select all individuals  that can be reached from t1 

and that returns

t2 (direct arc)
t3 (direct arc)
t4 (indirect arc through t2)

?

Thanks

Alessandro
