Hi,

With the latest develop/7 sources (commit 8dc86c42) and under OS/X 10.6.8, string literals, instead of URIs, are returned from SPARQL queries. The query:

   SELECT * FROM <http://www.openlinksw.com/schemas/virtrdf#>
   WHERE { ?s a ?t }

returns rows in the form:

   result:
   
[s=uri<http://www.openlinksw.com/virtrdf-data-formats#sql-varchar-literal-nullable>,
   t=uri<http://www.openlinksw.com/schemas/virtrdf#QuadMapFormat>]

Changing the query to:

   SELECT * FROM <http://www.openlinksw.com/schemas/virtrdf#>
   WHERE { ?s a ?t }
   ORDER BY ?s

returns:

   result:
   
[s=string("http://www.openlinksw.com/virtrdf-data-formats#sql-varchar-literal-nullable";),
   t=uri<http://www.openlinksw.com/schemas/virtrdf#QuadMapFormat>]

All is well if "ORDER BY" is followed by "LIMIT".



Thanks,
Dave
