Hi !

Currently I'm writing a Masters Thesis at the University of Aarhus where I try to 
define an ODMG 2.0 language binding for Beta, that would enable Beta to work together 
with all ODMG 2.0 compatible commercial Databases (at least in theory).

The project has just started and some kind of prototype is expected to be
delivered this summer, so if you are interested I could send you some of the
Design documents etc, as we proceed ??

With kind regards
