      Description

      I want to be able to CONSTRUCT graphs with reification.
      So by executing something like:

      PREFIX ex: http://example.org/
      CONSTRUCT { 
      ?s ?p ?o
      ?st ex:was_told_by ex:Bob
      } WHERE {
      ?s ?p ?o .
      BIND (<<?s ?p ?o>> AS ?st) .
      }
      

      I should be able to create an RDF graph where each statement ex:was_told_by ex:Bob
      Important thing: there may be a typo in quoted query, so do not stick much to this exact text. What I want to be able to do is to CONSTRUCT statements with rectification, I have tried many ways to do this with 1.4.0 and did not manage to make it work with GraphQueries (although with Select quires it is more or less working).
