Re: Comments on TA version 0.9

Mike
I took away from the discussion a slightly different interpetation of the QR
review.   Following are the notes that I took during that discussion:

v    What is the role of modeling/ Choice of UML
v    Resolution:  If you choose to formally model within ebXML -  you must use
UML.
             -  BUT the Technical Architecture MUST BE ABLE TO SUPPORT OTHER
              MODELING METHODOLOGIES exchanged with external sources
             - This will allow for gradual adoption, with loosely coupled
             compliant components
             - The presentation of the TA document obscures the ability to
             support gradual adoption of ebXML.

   Therefore, the BP documents should prescribe a single modeling approach, but
   the technical architecture has to support multiple modeling languages, as it
   has a requirement able to accommodate a gradual adoption of ebXML.

Mark participated in the meeting and I must say represented the requirements
 document well,  insuring that we embrased this agreed upon specification,
 completely.

regards, Melanie

Thanks for the quick note, Scott, but your response raises more questions than
answers for the majority of us on this list who are not in Tokyo.   I would
appreciate getting an answer when you have time.  Specifically, please elaborate
on not meeting the requirements to pick "a single modeling technique and
methodology, and adopting existing specifications".

I appreciate the need to come to a consensus regarding the TA spec - and that
will probably require several folks resigning themselves to agreeing to
disagree.   However, I was not trying to debate issues when I raised my
questions.  If you look at the questions again, I am only asking to understand
the basis of your vision and assertions.  Please respond when convenient.

Thanks,

Mike
