It sounds pretty good - but if you remove the cross database aspect Fredrico
(and myself) would like,
you could mandate the type_codes and interfaces and let the implementations
be DB specific. In this way, you keep the module author's lives
(reletivaly) simple while adding benefit for the users. I know, I know, its
down the line in what you're talking about - but I just want to keep the
goal in sight. I think merging the type_code from output with the extended
input types (you had a good list), even if interfaces are not defined to Do
anything with the information, would be another good step. That way, you
could move from DB to DB and the type_ids would at least be the same (for
similar columns), reducing the burdon on the users.
