Hi I have attached a file which is a trace of the request produced by using TamperData in Firefox. My version of Virtuoso is 6.1.3127 so maybe it is fixed in the 6.2 releases?
I can also reproduce this error using SPASQL by making the request via the ADO.Net provider. This is the XML output I get: <sparql xmlns="http://www.w3.org/2005/sparql-results#"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.w3.org/2001/sw/DataAccess/rf1/result2.xsd";> <head> <variable name="g"/> </head> <results distinct="false" ordered="true"> <result> <binding name="g"><literal>http://www.openlinksw.com/schemas/virtrdf#</literal></binding> </result> <result> <binding name="g"><literal>http://localhost:8890/DAV</literal></binding> </result> <result> <binding name="g"><literal>http://www.w3.org/2002/07/owl#</literal></binding> </result> <result> <binding name="g"><literal>http://localhost/VirtuosoTest</literal></binding> </result> <result> <binding name="g"><literal>http://localhost/TurtleImportTest</literal></binding> </result> <result> <binding name="g"><literal>http://example.org/</literal></binding> </result> <result> <binding name="g"><literal>http://example.org/bnodes/</literal></binding> </result> <result> <binding name="g"><literal>http://example.org/VirtuosoEncodingTest</literal></binding> </result> </results> </sparql> I will try out the 6.2 release and see if that makes a difference Rob ---------------------------------------- From: "Sebastian Trüg" <[email protected]> Sent: 04 March 2011 08:41 To: [email protected] Subject: Re: [Virtuoso-users] Major bug with Virtuoso SPARQL Results See also this closed bug report: http://sourceforge.net/tracker/?func=detail&aid=2995846&group_id=161622&atid=820574 On 03/02/2011 02:42 PM, Rob Vesse wrote: > > Hi all > > I've found what appears to be a major bug with Virtuoso's SPARQL results > for one specific query namely: > > SELECT DISTINCT ?g WHERE { GRAPH ?g { ?s ?p ?o } } > > When this query is executed results come back as elements in > the XML results rather than as elements.
