Subject: PR001 - new MC spec direction

On last week's call we were asked to
write up something that would describe the scope/details of the proposal
we made w.r.t. moving MakeConnection into a new spec. I think the
text below should cover that.
Proposal: Move MakeConnection into a new
specification
Details:
Move the MakeConnection (and related portions of the RM spec) into a new
specification that will be developed by the WS-RX TC. The overall
scope of the TC itself will remain the same. The scope of this new specification
will be limited to the development of a mechanism that will establish a
transport-specific back-channel. This back-channel will be used in
situations where an anonymous URI is used as the destination EPR for messages
and there is no existing/appropriate back-channel available. The
specification will try to address the use-cases that have be identified
during the recently discussions in the WS-RX TC. These include:
- Attempt to not restrict the RM processing model choices when switching
from async to sync MEPs
- Support for multiple endpoints behind a virtual RM processor
- Support for gateway scenarios (on RMS and RMD)
- Support for allowing an RMS to advertise its support for MC
- Support for allowing an RMD to advertise its intention to use MC
- Support for anonymous AcksTo (in particular for the Sequence Faults)
- Support for unreliable-in/reliable out scenarios
- Retain the notion of the RMS being the initiator of new Sequences
- Support for uniquely identifying anonymous endpoints
As this specification will compose on top of the base WS-RM specification,
the base WS-RM specification's issues will be prioritize over the MC issues.
The list of PR issues that this new specification will address are:
i001 WS-Addressing comment on ws-rm related to use of extended anonymous
uri ws-rm design *
i015 RMD polling ws-rm, ws-rmp design
i027 Where do Sequence Faults go when the RMS is anonymous ws-rm
design
i028 MakeConnection preconditions are unclear ws-rm design
i029 Opaqueness of URI identifiers not preserved by RM anon URI ws-rm
design
i030 Facilities to support optional MakeConnection underspecified
ws-rm design
i031 Scope of MakeConnection is unconstrained ws-rm design
thanks
-Doug
