We intend to revisit the idea of mapping ACEDB models into 
OPM (Object-Protocol Model) schemas in order to allow having 
OPM `views' of ACEDB models. If nothing else, the OPM editor
provides graphical browsing and documentation capabilities
(postcript diagrams and latex document of classes) that may
help documenting ACEDB models.

We need for this an (independent) parser for ACEDB models based 
on the latest ACEDB BNF syntax. 

From discussions with Eric (LBL) and Detlef (DKFZ), it seems that 
no such parser exists.  We have developed developed one with yacc & lex
in Nov 1992. It would be nice to have an updated version developed 
with yacc++ (Detlef and others highly recommend yacc++).

We are wondering if Jean or Richard ever cared to develop such a parser 
for ACEDB models that others can use. I think that such a parser is 
very desirable for keeping all ACEDB related efforts synchronized.
We are also wondering what is the latest version of the BNF for
ACEDB models- the last one we are aware of is dated Dec 1992
and was part of an incomplete document authored by Jean & Richard.

I would appreciate anyone's help in clarifying our questions.
