Scott
I think your ideas are headed in the right direction.
One other thing thoug, on your first point of getting the Party Profile what
eCo did was define a standard ending for a url, e.g. www.mycompany.com/eco
that was used to get the base XML document from which everything else was
bootstrapped.

David,
Yep. Some messages are sent without an agreement. It does however make me
think
on the need to rank technology bindings (below).
Marty,
I'm somewhat confused on what I indicated to be an opposing
view..............?
All,
what is in my head now on the base PP/Spontaneous Business relationships
are:
-> A Party has one PartyProfile.
That PP *may* be registered into a Registry. We may consider
defining an InfrastructureBusinessProcess with specific technology for
obtaining
a PP directly from a Party once you know of the business. Results of this
request could be "here is my PP", "I maintain my PP in this Registry, so go
here",
etc.
-> A PartyProfile contains one BusinessProcessCollection. I'm suggesting
this as an
explicit entity in order to keep the supported BusinessProcesses within one
containment
in the Profile, in order keep the door open for a Party to present other
information in the
Profile not related to BusinessProcesses.
-> The BusinessProcessCollection contains BusinessProcessDescriptors.
A BusinessProcessDesciptor contains one reference to an
IdentifiableBusinessProcess,
which could be a reference into a Registry for a RegisteredBusinessProcess
(default), or
some user-defined way (same issue as Partyid and URI default).
A BusinessProcessDescriptor also contains a list of steps/actions that the
business
supports within that IdentifiableBusinessProcess. Each supported
step/action contains
a list of technology capabilities (perhaps ranked to support spontaneous
business
invocation success likelihood) that indicate what *can* be used, not what
*will* be used.
None of this is an agreement, and all of it is associated with a Party.
Further, we would define several more InfrastructureBusinessProcesses to
facilitate
"coming to an IdentifiableAgreement" instance (which *may* be registered in
a Registry or held
privately as long as its identity makes sense to the involved Parties)
to be used for future business transactions between those specific Parties.
(This leads to more thought on required underlying
InfrastructureCommonErrors, etc....)
Thoughts?

I agree Marty, agreement is reached when B returns a message back to A. The
key point is though that some messages are being sent *before* there is any
agreement.

I agree with David on this one. Even in a single profile, there could be
different technology bindings for different processes or alternative
bindings for the same processes. This is the reason that the tpaML
proposal has multiple delivery channels.
In David's scenario, there is no prior agreement. However the function of
the agreement is performed by B including the selected binding information
of Party A in its first message to A. There is even a modicum of
negotiation here because A certainly has the option of rejecting that
message for whatever reason.
What we are really doing here is beginning the negotiation of the details
in the PPs and the protocol for using them.
Regards,
Marty

David,
On yesterday's TP call we discussed some invariant relationships for a
Party and a PP.
This was done as assumptions to the requirements for TP.
There was general consensus that a Party has one PP. Within that PP, there
would be things
like descriptors that describe the supported business processes. They would
point to
identifiable Business Processes, and contain technology mapping
capabilities for
each step/action (essentially roles) supported within that BP.
Note: The PP says nothing about any agreement to anything, just what
BPs are supported by a Party, and the *technology capabilities* per
steps/actions.
At the instance level of an agreement, it would reflect that for BP 1,
step3 it must be via email
for you and I. Another agreement instance may reflect for the same BP/step,
it is HTTP.
Thoughts? It would help if we, TRP, TP, BP could get agreement on some of
these
base invariants soon.

Catching up on email ...
Party A might have to put Party B's information into the header, either by
value or by reference, because there Party B might have several alternative
profiles and Party A needs to identify which one ...

OK, in this case, it's a PP instead of a PA.
Having obtained the binding information, I don't understand why Party A has
to put Party B's binding information into the header of a message to B.
What party A has to do is to configure its system to send messages to Party
B using Party B's binding information.
Do we have some mismatch as to what is in the binding information and how
it is to be used?
Regards,
Marty

Marty said ...
>>>This [transport binding] information cannot be specified in the message

Not necessarily. There is a use case where:
1. Party A downloads binding information about Party B using a simple URL
from a web site either Party B's web site or a registry (UDDI?)
2. Then, in the header of a message, Party A refers to or includes Party
B's
binding information as well as similar information about Party A and
specifies which bindings to use.
3. Party A sends the message to Party B
Where's the TPA (or is PA now) ?

Expaaaaaanding:
"Bindings to specific technologies belong in the TPA."
I am using the term "bindings" to refer to the means of specifying, for
example, what communication protocol is used with the messaging service for
a given business relationship.
Assume that the messaging service can be used with more than one
communication protocol, communication security definition, etc. What is
needed is a means of specifying the name and parameters of the
communication protocol to be used for a particular business relationship.
This information cannot be specified in the message header because the
message cannot flow without a communication protocol being in place.
Therefore, the binding must be specified somewhere outside the messaging
service. The natural place is the TPA. The transport section of the tpaML
specifies what communication protocol and communication security parameters
will be used for message exchanges under that TPA.
What may be needed in the messaging service specification is some kind of
abstract definition of how information is exchanged between the messaging
service and the underlying transport level.
Regards,
Marty

In consultation with other members and having thought about the binding
issue
I have
come to think that bindings to specific technologies do not belong in the
spec at this time. I think
that an RS implementation must provide an interoperable TRP based api.
An RS implementation is free to provide any other APIs in addition to the
required TRP api as an implementation specific detail.
