Subject: RE: Special note for CPP members


I do humbly apologize for jumping out of protocol.  I have just been
struggling with how to automate the creation of a CPA - much along the lines
of the way another vendor was substituted using UDDI during the OAG Vendor
Challenge in November.  Working at the architecture and integration level
and not the implementation level for the past several years has hampered my
ability to crisply state my issue that I thought Duane represented quite

I understand that things must be done in stages and the first stage of
articulating the CPP and CPA in a useful manner is of paramount importance.
I don't want to interfere with the excellent work that has been done or add
another burden.  I agree that just being able to implement a CPA that two
human beings have negotiated is an excellent and necessary first step.  I
didn't mean to jump to a future requirement as an urgent need and perhaps
given all the work you are doing to prepare for Vancouver I just cluttered
up email space that is better served with comments from the experts.

If you have concerns about the CPP and CPA that you can articulate, the
place to present them is on the TP listserver so that the team can
and consider them in designing the CPP and CPA.

 Thanks Duane
As I have read through the drafts I have wondered how we would build CPA
generation into our Commerce Broker capabilities - wasn't intuitive from
documents.  We need a scripted process that sets precedents and
correctly so that any system can reach the same results for a generated

Hello all:

As we conclude the TA Specification and the disposition of comments, it
has become apparent that there is a potential shortcoming on
specifications regarding the Trading Partner issues, specifically
concerning CPA generation from CPP's and business processes.  In order
to facilitate CPA negotiation,  people who are building reference
implementations have informed us that they believe it is necessary to
observe a standard protocol for deriving a CPA from CPP's.

Therefore,  we have added two small sections to the technical
architecture specification (NOTE: not officially approved by the TA team
yet) which read as follows:

"CPA negotiation SHALL be strictly defined.   Issues such a precedence,
prioritization and the mechanics of the negotiation process SHALL be
addressed in the ebXML Specifications governing Collaborative Protocol

"A CPA negotiation protocol SHALL be defined by the ebXML TP Project

Comments please? (Today if possible)

Duane Nickull
