Constructing URI

Hi all -

I want to construct the URI of a resource using other pieces of information
from an RDF graph. Let me try to explain :

<http://www.example.com#A> <http://www.example.com#P1> <
http://www.example.com#B>
<http://www.example.com#B> <http://www.example.com#P2> "valueB"
<http://www.example.com#B> <rdfs:label> "labelB"@en

I would like to do a CONSTRUCT query in which a resource C would have a URI
built by concatenating the URI of A (http://www.example.com#A) and the
language information of the resource B (en). The resulting URI would be "
http://example.com#A_en".
Is it possible ? could anyone point me to an example ?

If it not possible with the language information of the label of B, would it
be possible to build the URI of C using the property P2 of B ? (the
resulting URI would be http://www.example.com#A_valueB)

Thanks for the help !
Thomas
