Hi Marcus,
Here are some answers to your questions:
ebXML is a complete set of specifications for the message-exchange
portions of electronic commerce. Work is in progress both in ebXML
and in UN/CEFACT to continue the work in progress on business-process
specifications that would be used on top of the ebXML specifications. The
core components specification will define the structure of business
documents.Work is also in progress on an ebXML specification for
automated negotiation of the contents of a CPA. The completed ebXML
specifications cover:
- Message exchange
- CPP and CPA, profile and agreement on the technical parameters of
message exchange.
- Business-process specification schema (BPSS), which defines message
choreography and provides the interface to business process definitions.
(Work continues on extending this to richer functionality.)
- Registry, for storing information about trading partners and enabling
trading partners to search for each other.
Companies are in the process of implementing these specifications.
An interoperability team is working on specifications for testing
interoperability. In my opinion, ebXML is functional for
collaborations between two business partners except that business process
specification work is still in progress in ebXML and UN/CEFACT. However,
two companies can define a business process to suit themselves and use a
BPSS instance document to connect it to the rest of the ebXML
suite.
One alternative to ebXML is Web Services, a project primarily of the
World Wide Web Consortium. At this time, the Web Services
specifications deal with business processes in which there is a client
and a service provider and the service provider dictates all the terms
and conditions. Another alternative is to use "classic EDI"
(Electronic Data Interchange), which has a rich set of specifications but
is quite complex and provides no automation of the process of linking
partners with each other.
A "trading partner agreement" (TPA) is an EDI function.
It is a text document that defines both the business process terms and
conditions and the technical terms and conditions for exchanging
messages. A TPA has to be read by programmers, in each trading
partner's enterpprise, who write or configure the run-time code needed to
implement the collaboration. In principle, the technical terms and
conditions in a TPA could be replaced by a reference to an ebXML CPA but
I do not believe that a standard specification exists for doing so. I
believe that the UN/CEFACT architecture document talks about a TPA as
including a CPA but I do not believe that any work has been done to
support such a statement.
As to influencing the earnings and revenues of companies, such
information is quite proprietary within each company. I can only
say that companies are implementing ebXML, so they must believe that it
will improve their figures.
As Monica pointed out, if you subscribe to the ebXML-cppa-comment list,
you will be able to ask further questions and get answers from the people
on the team.

mm1: Markus, contact Sacha Schlegel and Martin Sachs by posting to
ebxml-cppa-comment. You can get to this from:
http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=ebxml-cppa.
There has been quite a bit of discussion about trading partner
agreements, the role of CPPA and UBAC. Thanks.
