Re: A newcomer's question about ebXML

[Martin W Sachs <mwsachs@us.ibm.com>]

It is correct that the collaboration protocol agreement (the document
mentioned in the previous email) contain the "channel" definitions. However
by the time the first messge flows, the information in the CPA has already
been configured into the runtime system.  In the IBM tpaML proposal, there
are the following options:

   A single delivery channel for the entire agreement
   A separate delivery channel for each action request
   Dynamic selection of delivery channel by the runtime on a message by
   message basis.

Regards,
Marty

Subject:  Re: A newcomer's question about ebXML



if i understand the question ...

if by the 'document', you mean the ebXML Header Document, then the answer
is 'not directly'.  the idea is to keep ebXML transactions  independant of
transport mechanism/channels.  However, the Header will contain Trading
Partner Agreement information, which may reference a seperate document (the
Agreement between the two parties) that identifies the proposed
'channels'.  I suggest you check out the work being done by the ebXML TP
team.

if by the 'document', you mean the ebXML Message, then the answer is 'this
is up to the parties involved, but probably not'.  ebXML Messaging Services
do not dictate the content of the business data/payload.  This work is
under the area of Core Components and Business Processes.

hope that helps.
