Re: Constructing URI

hi, if your in urgent need of such a function
and are using openrdf sesame check out the following post : 

http://www.openrdf.org/forum/mvnforum/viewthread?thread=1816#6646

you could easily adapt that example to concat two values.

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 ) 

Hi Thomas, 

This is not possible using standard SPARQL, though some implementations may provide extensions to allow it. 

It is one proposed feature that the new SPARQL Working Group is considering:
