Re: Collaboration Services (was: Business Service Interface)

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

The IBM tpaML proposal includes sequencing rules which specify the required
order in which each party can issue messages to the other party.  This
appears to cover a large number of the practical cases.  The run-time
middleware can verify whether the sequencing rules are being obeyed. At the
TP team Face to Face earlier this month, we spoke about developing a more
general model such as a event-condition-action state machine for the cases
where the tpaML sequencing rules are not sufficient.

Marty

I also think that in many (if not most) of those cases, the sequence is not
managable by sequence numbers or any other document-local rules, but
requires interaction with something like actual business objects at one or
both ends of the collaboration.
...
In other words, sequencing of business collaborations may require
collaboration software with some business intelligence, it may not be
manageable exclusively by sequence numbers or linked lists.

I don't know whether "the sequence" and "sequencing" would be the best
terms
(I might rather use something like "Temporal constraints between (Economic,
Business?) Events"), but I strongly agree with the assertions: "is not
manageable by sequence numbers or any other document-local rules" and "it
may not be manageable exclusively by sequence numbers or linked lists".
