Subject: RE: Initial correlation of ebXML Transport requirements with CORBA services


But doesn't using Corba, require that an ORB is implemented at each end of
the two parties that want to communicate. Not everyone will want to
implement an Orb even if it is available from multiple suppliers with open
standards.

It's also quite possible to define the interfaces to objects in terms of the
documents they accept and generate in turn, for example look at the way the
eCo specification specifies "Services" and "Interactions".

You can also with XML Schema's have documents that are extensible and can
inherit characteristics from other documents (a colleague at Commerce One is
one of the author's of the upcoming W3C Schema spec).

This means that you can achieve the benefits of an object oriented approach
without having to implement a particular architecture on your system.

Subject: RE: Initial correlation of ebXML Transport requirements with
CORBA services


Hi Scott,

Very true.  One of the reasons that I think CORBA will serve ebXML 
well, however, is that I also attended one of the other group's 
meetings in San Jose and they were talking Objects.  So it seemed 
to me that CORBA would suit ebXML requirements nicely as they'd 
want an ORB.  Of course, one that's already available from multiple 
vendors (a single source for may companies is a worry), is a plus. 
Our specs are open (and we don't charge if you get them on-line) 
which I hope would help make them acceptable to the UN.

Best regards,
Henry
