ADQL/S-to-ADQL/X translator

[Kona Andrews]

Dear all,

My colleague Jeff Lusted has now published a prototype of his ADQL/sql
to ADQL/xml translator, including 

 - a downloadable demonstrator

 - a BNF grammar for ADQL/sql, based on SQL-92 and the current ADQL standard 
   (which I hope we can use as a starting point for producing a new grammar)

 - some important discussion about the issues involved in producing an 
   ADQL/sql grammar from the pure SQL-92 BNF, and problems/issues with the 
   current ADQL/sql standard.

You can find all of this information here:

  http://www2.astrogrid.org/Members/JeffLusted/adql-compiler-adqlstox/

In particular it is useful to read his discussion document, which can be 
found here:

Please let me know if you have any difficulties accessing any of the
above material on the new AstroGrid plone site.

All the best,
Kona
