Re: [dotNetRDF-Develop] FROM and FROM NAMED

Hi Wadea

I understand that you should use GRAPH patterns to determine what graphs to
query.

For example

SELECT *
WHERE
{
   GRAPH ?g
   {
      // patterns
   }
}

This way you can then narrow down the ?g by using it in further filters or
graph patterns. Does this help?

Tom

  Dear Sir/Madam
I have developed a SPARQL endpoint using dotnetrdf library ,  it works
perfect when choosing an external file (Turtle file)
but when try to execute query that have already "FROM" or "FROM NAMED"
clause it is return an empty result

is there an example (sample code) to use this library when we want to
depend on query itself to determine default and named graph?

thank you a lot
