Re: [Virtuoso-users] Possible compatibility between 6.1.16 and 6.1.8?

Thu, 30 Jan 2014 15:31:30 -0800 

Hi Hugh!

Great thanks!

Is ther a way to follow the evolution of the resolution of this issue?
And normally, the fix will be in 6.1.9, or there will be any ways to add the fix to the 6.1.8 codebase (maybe via a patch file?) 

Thanks,

Fred


Hi Fred,
This looks like a general bug in the latest builds, as I get the same error running the following similar query against our v7 LOD Cloud server, http://lod.openlinksw.com/sparql: 

select ?s ?p ?o (DATATYPE(?o)) as ?otype (LANG(?o)) as ?olang
where
{
  {
    select distinct ?s
    where
    {
      ?s a ?type.
    }
    limit 50
    offset 0
  }
  ?s ?p ?o
}

and have reported this to development to look into ...

Best Regards
Hugh Williams

Hi,
I am wondering if I found a compability issue between VOS 6.1.6 and 6.1.8.
I did compile VOS 6.1.8 without any issues, then I ran with with a VOS 6.1.6 database file. There was no issues, and everything was working as expected, until I use the following SPARQL query: 


==========
select ?s ?p ?o (DATATYPE(?o)) as ?otype (LANG(?o)) as ?olang
where
{
  {
select distinct ?s from <http://localhost/datasets/organizations/import> 
    where
    {
      ?s a ?type.
    }
    limit 50
    offset 0
  }

  ?s ?p ?o
}
==========

If I am requesting the following mimes to the /sparql/ endpoint:

  (a) application/sparql-results+xml
  (b) application/sparql-results+json

I am getting the following content from the endpoint:


==========

          limit 50
          offset 0
        }

        ?s ?p ?o
      }
==========
Obviously, the error is related to the datatype request. However, I am not sure why it chokes there, and in that way. If I request the text/html mime, it works fine.
Is it just that something is missing in the 6.1.6 database that is now required by 6.1.8 related to these datatypes? If so, is this something I can create by hands? 


Thanks,

Take care,

Fred
