When we started ozone it was a 100% pure academic project. We looked through the
ODMG C++ specs (I think there was no definite Java paper out) but decided to do
our own stuff because it did not seem to be a problem to add a wrapper for
something later. Now it seems that we reached this "future" ;)

The answer to your questions is: We would really like to have and it should be
no problem to build an ODMG-compliant interface which implements say 90% or
95%of the spec. The last 5% could be real difficult because some things are
completely different in ozone and we do not want to break the ozone architecture
just to have some standards implemented.

Yes, an ODMG compliant interface seems to be an important thing to have. Where
can I find the ODMG Java binding spec? (the odmg.org server does not accept
connections at present) If it is as easy as I expect, maybe we will do it
ourselves.

Do you have any experiences building such an interface? Which ODMG compliant
OODBMSs are you using at present?


Best regards,
