[Virtuoso-users] Bug in SPARQL XML results

[Alexander De Leon]

Hi,
This is possible a bug in Version: 06.00.3123        

My endpoint is http://bio2rdf.semanticscience.org:8002/sparql

If you run the following query:

select distinct * where { <http://bio2rdf.org/pdb:1Y26> ?p ?o }

and ask for results in XML.

The resulting XML has this two problems:

1)  <results distinct="false" ordered="true">    
It says that distinct is false, but according to my query it should be true.

2) <result>
   <binding 
name="p"><literal>http://www.w3.org/1999/02/22-rdf-syntax-ns#type</literal></binding>
   <binding name="o"><uri>http://bio2rdf.org/pdb:Experiment</uri></binding>
  </result>
It says that the property (binding "p") is a LITERAL instead of URI. This 
confuses any application that consumes SPARQL XML

Removing "distinct" from the query fixes the problem.

Thanks,
Alex
