OMG Model Driven Architecture

[Cory Casanave <cory-c@dataaccess.com>]

For those of you who have involvement in the OMG as well as EbXml - you
should note some very important changes that are taking place within OMG.  I
should preface this with a caution that this is in-progress within OMG and
not yet official policy.

As you may know OMG founded CORBA as it's first technology base and has
since become the founder of the Unified Modeling Language (UML).  OMG has
spawned a number of very active domain groups which produce industry
specific specifications.  Until now OMG specifications were expected to be
CORBA specifications.  What is changing is that OMG is moving to become
middleware independent.  OMG domain specifications would be expressed in
terms of UML and then mapped to multiple technologies (Corba included).

This is a huge step.  No other cross-domain organization is technology
independent, I think we will see an overwhelming response as domain groups
use OMG to produce specifications that can be used on Corba, COM, EJB,
EbXml, MQ and whatever technology is hot next year.

The good news is that this opens the door for a tighter collaboration
between EbXml and OMG - they are now truly complementary.  The work that is
being done in the BP group fits well with the technology independent
modeling approach OMG would like to use.  OMG domain specifications may
become EbXml domain specifications via MDA.  Some of us have also been
trying to keep the OMG work and the EbXml work compatible - and it looks
like this is on a good track.

Below is a reference to the OMG initiative, which will be a topic of much
discussion at the OMG meeting in 2 weeks.  Those with cross-involvement may
want to stay in touch.

Cory Casanave
