But when we're all done with this, what do we expect out of the
Business>Process model? Is this somehow going to be put into XMI or
something
that ebXML compliant software can read to control the processes? I.e.,
the process would ensure that the authorization for raw materials,
fabrication and shipment occur seriatim (taking the Scheduling Use case
for example).

A lot of the usage remains to be determined.  The only official statements
are those included in the TechSpec Scenarios, in which the BP model
will be incorporated in repositories.  We also expect the core components
and BP model to align with each other, although that will be a two-way
street.

Informally, I could say:
1) The BP model is not all mandatory; that is, it is designed to be used
    in pieces, so that for example simple one-off purchase orders would
    use a little, while contract procurement might use a lot.
2) The model contains optional rules that could ensure proper
    sequencing of process steps.
3) I don't expect ebXML to produce software.
4) I do expect the BP model to influence software companies.

Am I making any sense?

It is a logical outlook that BP-XMI in appropriate "pieces" (as Bob puts
it)
will indeed play a role in implementations from software companies,
even if a BP-XMI formal specification does not exist in ebXML.

Also, not only an alignment with Core Components is likely,
but logically with TRP. An instance of the BP would define an instance of
the
TRP TSLA, which will configure an instance of the ebXML-aware Transport
for enforcing the BP process steps.

The system-level architecture is not completely clear, but this is a likely
outcome that is workable.

I agree, it is too complex.  The next revision (due next week) will
not be any better.  I'll raise an issue from your suggestions to
find a way to simplify for the rev after that.

Good.  At least we're moving in the right direction.
(Those were done much later than the first big diagram.)

They had a few listed problems; the next rev should map much closer
to 100%.
