Computation of maybe and definitely incoming bindings in subqueries

    XMLWordPrintable

    Details

      Description

      Currently, in subqueries the calculation of maybe and definitely incoming bindings does not work properly. The problem here is that ?o is added to the exogeneous variable, and these exogeneous variables are always injected when calculating these variable sets. For subqueries, they should not be injected though, as they open a fresh scope.

      SELECT * WHERE {
        {
          SELECT ?s WHERE {
            ?s ?p ?o .
            FILTER(?o=<http://o2>)
          }
        }
      } VALUES ?o { <http://o> }
