Re: XPATH for RDF ?

  We are doing something like that but I don't think
is going to be public, our language is something
like...

 
people.<ns:Person>.<rdf:type>'[<ns:surname>=="Surname"].<ns:name>

  give me the name of the instance of person whose
surname is Surname on the rdf model people.

  It's not difficult to implement and it would be a
good idea to have something like that being standard.

  Regards,
          Marc
