Re: TP requirements for BP

Karsten,

This list seems pretty comprehensive.  I have no additions or changes at
this time.  I assume that this will be input to our joint discussion in
Tokyo.

Regards,
Marty

I am sending this to just the limited metamodel list, because I have not
heard
back from any of the TP team yet, but want to start discussing this in
today's
meeting.

Hi,
In preparation for the 12 noon BP/CC metamodel meeting today I have put the
following list together of possible TP requirements for BP:

In general I am intending to present the following as TP background to BP
team:

CPP is the advertisement of capability.
CPA is the mutual commitment

Functional (business) content of TPP:

What are the business collaborations supported?
What are the service transactions supported within each business
collaboration?
For each service transaction:
  What type of contract is it governed by? (link to REA)
  What are the entry conditions (pre-conditions), stated as prior
completion
  of other service transactions, or specifically prior completed contracts
or
  economic events?
  What is the initiating message?
  What are the possible response messages?
For each possible response message:
  What is the exit conditions (post conditions), stated as resulting
completion,
  partial completion, or failure of the service transaction, or
specifically the
  resulting contract, economic event, or exception condition?
  Optionally, what service transaction do I expect to be initiated next,
  following this particular response message?

IN terms of requirements of TP for BP, I have identified the following, but
need
your comments, additions, corrections:

1. TP is all XML, therefore BP must make it possible to extract in XML
format
all the pieces of information that are specified as part of BP but required
as
part of a CPP or CPA.
2. TP supports thin or thick versions of CPP and CPA. Therefore:
  2.a. For thin version, BP must provide XML documents with distinct ID
referenceable:
    2.a.1. Business Collaborations
    2.a.2. Commercial Transactions (or "service transactions")
    2.a.3. Technical handshake patterns.
  2.b. For thick version BP and TP must use the same expression and
structure
for the shared part of definitions of
    2.b.1   business collaboration
    2.b.2. Commercial Transactions (or "service transactions")
    2.c.3. Technical handshake patterns.
3.  Since CPP is a subset of a BP definition, defining partner
capabilities,
there must be a way of subsetting:
   3.a.  Enabled service transactions within a business collaboration
   3.b.  Enabled responses within a service transaction
4.  Since CPA is a concise commitment, there must be a way of subsetting
and
overriding parameters of the BP definition, e.g. make optional mandatory or
vice
versa, override time-outs, etc.

Comments, additions, corrections?
