Subject: Re: [ebxml-dev] about cpp/a negotiation
A few clarifications on the exchange below:
Party B can't simply accede to Party A's CPP. Party B must also send party
A its CPP since that contains information that party A needs in order to
exchange messages. In most cases, it will be desirable to compose a CPA
based on the two CPPs is the usual next step. The composition can be
automated (see discussion in one of the appendices in the CPP-CPA
specification). However the composition process may require some
negotiation of mismatches. For simple cases, the negotiation can be by
phone or fax. The CPPA team's automated negotation project is specifying a
more general negotiation process that should be able to be automated in
most cases but may sometimes require human intervention.
In addition to its listerver archive, the automated-negotiation subteam has
a web site which can be reached from the CPPA team web site. The web site
contains the requirements document and the minutes of all meetings.
The negotiation process results in modifying of the initial draft CPA. The
actual protocol is being designed and there is no draft specification at
this time. In any case, the negotiation process has the same general form
as any collaborative business process and will be described by a BPSS
instance document. As with any collaborative business process, negotiation
is by means of messages exchanged using the parties' MSHs. The messages may
include partially negotiated drafts of the CPA.
Jamie Clark is discussing saving of a copy of the CPA for legal purposes.
However, Moon is actually asking about loading the contents of the CPA into
the runtime system for the purposes of configuring the systems for the
business arrangement governed by the CPA. Every party has to save the
contents of the CPA in a form such that it can be used to control the
runtime exchanges between the two partners. There is no specific
requirement about the form in which the CPA information is stored. People
usually refer to it as a runtime database. I believe that several companies
are working on CPA deployment tools. Perhaps some who sees this can reply
with specific information about deployment tools.
JSR 157, the CPPA API is a work in progress. If anyone on this listserver
knows the status of it, please post information here.

Subject: [ebxml-dev] about cpp/a negotiation

Let me offer a few very simple comments, and then more qualified experts
may wish to speak up.
Automated or sophisticated negotiation is not needed to initiate ebXML
transactions. One partner may offer a CPP, or a sheaf of CPPs, and the
other may simply accede to one (in a ebXML message) and by doing so promote
it to a CPA that will bind the both of them. The 1.0 specification
anticipates this.
However, some likely will wish to conduct fully automated negotiations of a
CPA between strangers. The two-party method for doing so is being
articulated by a separate 'negotiation' subteam of the ebXML CPPA team.
You might want to read the archives of their separate mailing list (at
http://lists.oasis-open.org/archives/ebxml-cppa-negot/) to learn more of
their work.
Also, many users may not wish to do much "re-configuration" within a
specific transaction set after a CPA is fully negotiated. Here is the
reason. There are risks associated with the conduct of a multi-step
automated transaction. We expect that parties will wish to evaluate, and
fix, those risks before running the transaction, by interrogating the
proposed CPA (and the business transactions referenced in its
process-specification). Once a satisfactory set of channels, signals,
time-out rules and business rules have been set, the parties are free to
run the process without further human intervention, because they are
satisfied with the finite, known set of outcomes. A post-CPA change to
the "configuration" that changes the set of possible outcomes, or the risks
that the parties elected to assume, might make the set of transactions less
attractive, less automatable, or more erratic to its users.
As to saving CPPA parameters, yes, I expect that most parties would save a
persistent copy of any CPA to which they have agreed, in a manner that
allows demonstrably accurate reproduction of the original artifact. This
is for exactly the same reason that you save a signed paper contract. It
is part of the evidence you will need in order to prove that you have a
binding deal, and what the terms of that deal are. I will leave to others
the question of whether a database is the right medium.
Good luck and best regards Jamie Clark

Dear all,
We have some questions about the implementation of CPP/A. In the
specification, there are no remarks for automated negotiation and
configurations of CPA. We want to implement the ebXML CPP/A standards
for defining business profiles and the conditions that allow
integration between businesses. If we implement automated CPA
negotiation tool, it will be provided to create a CPA from two given
CPP documents.
Our questions are: How can be negotiation done? Is CPA document
itself modified or it¡¯s just transferred using MSH?
After negotiation, How can we configure CPA parameters? Where? Does
every party have to save configuration file in it¡¯s own DB? Are
there any API for CPP/A? I came across JSR 157 ebXML CPP/A APIs for
Java but it¡¯s not available I guess.
Anyone else done this and have some "shareable"
resources/info.artificts that we might be able to reuse?
Thanks in advance.
