+2  Q: 

how we can create a quesry based on SPARQL to see the value of some data type property?

I create this query:

PREFIX VB: <http://VBnet#&gt;
SELECT  ?x ?y
WHERE 
{
  ?x VB:HasName ?y
}

HasName is one datatype property. When I run this query in Protege, system show me just the subject without any value for datatype property. mwans ?y is empty. Also when I run in jena system show me just:(String)

How can I see the value of datatype property the value of ?y?
Thanks
