ADQL/S-to-ADQL/X translator

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
