Hello there,

Is something like that possible? How can I accomplish this check? do I

The easiest way would be in Java with regular loops, but it may also
be possible to do it in SPARQL.
In the proposed SPARQL 1.1 I think you could do it with a subSELECT,
but I don't have an implementation to hard to try it on.
