Re: TPA & ebXML; more thoughts

[srh@us.ibm.com]

Some more thoughts:
Eventually we need to think about the end to end sequence within the ebXML
environment, meaning, when does the
RegRep get accessed for such configuration information, etc. Thinking of
the TPA as a configuration file,
requires identification (TPAid) but further requires context (not to go
into this here as CC/BP are currently wrestling this concept).
So, I suggest we think TPAidContext and TPAid.

Performance and Configuration Changes leads to thoughts toward
a TRP implementation should be able to cache a Config file (TPA)  document
as a configuration for a process between specific
partners. We could consider some sort of "dry-run" capability of a business
process where it would give the TRP engines
the opportunity to insure they are ready with the correct configuration by
TPAidContext and TPAid.
They could remain "ready" (have cached
the config file if needed, alocated system resources if needed, etc) for a
given period, and could expose TRP-level
common query interfaces (more thoughts here abound) to obtain the
ready-timeout period, etc. This leads to
thinking about the ability to force a cache purge during the dry run for
cases where the config file has changed.

etc etc.

Hello John,

Thanks for this document. Just to add a comment, the negotiation of a
Trading Partner Agreement itself can be done using the ebXML framework. A
tpaML document could be exchanged (possibly several times) between two
trading partners over the ebXML framework until the trading partners have
come to an agreement over its final form. The final tpaML document could
then be used to provide configuration information as you mentioned in your
email, for all future ebXML exchanges. Although this brings us to a chicken
and egg problem of, how the first exchange was possible without a trading
partner agreement!
Just some thoughts.
