My understanding of ODMG standard is superficial, but the motivation of examining Zope's standard compliance are as follows: (pls correct me if I'm wrong)

(1) how well it integrates with Corba - i.e. can I access Zope functions from programs written in perl/C/smalltalk/Java via corba, and have zope reuse Corba components written in these languages.

Corba integration does not exist, but it would not be dificult to do. As a corba client, you could take some third party python corba package and integrate it into a Zope product to create "CORBA Methods" that would word presumably like External Methods. As a CORBA server you could create a new ZServer module. Remember, ZPublisher, the 'heart' of Zope, is an Object Request Broker (ORB) that maps quite cleanly onto CORBA. In the past when ZPublisher was Bobo, I beleive there was even some work done to make Bobo corba aware, I'm not certain. In any case there has been no demand on us for it for a while now, corba is not a very active standard. XML-RPC seems to fill it's shoes quite well.

(2) how well it complies with the OQL standard - i.e. is it query-lanugage compatiable with e.g. CA's Jasmine ii

It is not OQL compliant at all, however I see no reason why it would not be easy to make it so.

(3) Zope's architecture is so user-friendly and extensible that i am very pleased with it on small projects, and would be very eager to use it for a large scale implementation if I can find out how it stands re (1)/(2).

It is suitable for large scale implimentations regardless of 1 or 2, it just doesn't support 1 or 2.

From the replies received, I gather Zope is not very advanced in these directions, psychologically if not actually. I beg any core developer might explain that it will take 3 months'/years' work to make these happen, for example?

I couldn't tell you, but you could take a hack at it. I belive there are a couple Python corba packages. -Michel
