Re: XML format for SPARQL queries?

In Datao (cf datao.net), we developed a RDF representation of (a subset of)
SPARQL. Plus a RDF <-> Java beans ->SPARQL mapper.
(Plus a GUI on top of all that)
This part of the tool could probably be extracted as a standalone lib.
But as far as I know, you are the first person to express such a
requirement.
