RE: Storage of UML models

[MERCEY Jacques <JMercey@MEGA.com>]

Probably I missed something in the discussion but I haven't read anywhere
that UML was a requirement for ebXML.

The only thing that ebXML project teams have to define is behaviour and
interfaces. The way a tool vendor will implement RegRep or BP specifications
is out of scope. Of course, UML is a good way to define behaviours and
interfaces and we will go that way. But what is, at the end of the day,
stored in a repository is the implementer's problem; he can store UML models
or whatever else he wants. The only mandatory thing for him to do is to
expose what he has stored in an XML format compliant with the ebXML
metamodel. 

The same for a BP tool vendor, he can define collaborative processes with
whatever paradigm he wants as far as his clients are comfortable with that
paradigm. The only mandatory thing for him to do is to publish/read those
collaborations in/from an XML format compliant with the ebXML metamodel.

So, I am very surprised to see that translation to XML would  NOT be a
fundamental service. In my opinion, XML exposure, and hence XML translation,
is THE fundamental service.

Please, correct me if I misinterpret your thoughts.

I agree with Terry's assessment that:

"Translation to XML is a service implemented on top of a repository
and is NOT, repeat NOT, a fundamental function of a repository or
a registry.".

In fact IMHO, translation from UML to XMI is very likely to be done by
off-the-shelf tools
(e.g.  Together, Rose and IBM's  XMI toolkit etc.)

When reading the draft Registry Services v0.4 spec keep in mind that it is
still

in early stages of definition and still evolving. Comments from a BP
perspective
would be
very useful in this formative stage.
