Hi Pedro and colleagues!
I've just published the ADQL Parser as an Astrogrid component. It is available from our deploy site at http://deploy.astrogrid.org/wiki
The site also has a link to further documentation. The source should be available from CVS by anonymous access: the project is astrogrid/adql2. Details are available from the site...
http://deployer.astrogrid.org/software/adqlparser-2008.2/cvs-usage.html
There are two sets of BNF diagrams available. One of them covers my reading of our replies to the RFC page, so is possibly worth examining...
Regards
Jeff
