I've released some updates to the SPARQL query service. The code is now running on ARQ so should now be conforming to the SPARQL Candidate Recommendation.

I've also fixed some bugs and issues with data set creation that was stopping queries being submitted with the data set defined using, e.g. a FROM clause rather than a default-graph-uri parameter.

The upgrade to ARQ 1.3 also let me swap from my custom JSON output method to the draft specification being written by Kendall Clark et al.

I've left the AJAX Client alone for now as an example of natively processing the SPARQL XML results format. But it should be possible to use the newer SPARQL Javascript library as an alternative. I need to have a closer look at that to look at API differences and perhaps get it hosted here also.

The other minor tweak I've added is support for a query-uri parameter. This allows clients to specify a URL from which the desired SPARQL query will be retrieved. This is an extension to the SPARQL protocol which has been deferred by the DAWG until more implementation experience has been gathered. I'd be interested to hear if you use it.

I've a few other extensions to add, but thought I'd get these public first. More soon...
