Subject: May 12 Minutes
Minutes from the May 12 meeting are attached. --Pete Pete Wenzel <pete@seebeyond.com> Senior Architect, SeeBeyond Standards & Product Strategy +1-626-471-6311 (US-Pacific)
1. Roll Pete will chair in Ian's absence Present: Dale Doug Jacques Jeff Matt Pete 2. Review revised plan - Ian has posted after discussion last week Jacques has a conflict with the 29 Jun F2F date, and the weeks around it. Would be in favor of moving it 2 weeks prior (the week of Jun 14-18). Jacques or Matt could host (Bay Area or Ottawa). Everyone can make Jun 16-17 (Wed-Thu), potentially in Ottawa. ACTION: Matt to confirm facility availability for these dates. Matt: We may need to adjust our deliverables to accommodate the accellerated Draft 1 schedule. Individuals will need to prioritize it higher in order to complete before the June F2F. F2F agenda should include: Review of Working drafts Identify areas that need rework Scoping Draft 2 contents 3. Review Matts payload services proposal a) Format of propsal - all work items sholube be started this way? b) Content - is it the right "stuff" at the right level Doug: It's unclear whether the services are provided to the user by an MSH, or requested of one MSH by another MSH. Seems to be a mix of the two. How does each service affect the protocol? Transformation seems one-sided; generally occurs prior to presentation, not transmission. Jacques: If we offer a payload-level Ack, we need to understand payload content. (As for RosettaNet) Pete: For service specification within the message, it would be more appropriate to enumerate in the Manifest rather than MIME headers, keeping in mind that MTOM/XOP may be used in the future. Jeff: Yes, this would be like a list of processing instructions. Matt: Agree; this makes ordering, etc. easier. Doug: Sun submitted an XML process pipelining model to W3C that relates to sequencing of operations. May be useful for this purpose. Will forward a pointer to the group. Matt: Can/should this be done in CPA also? Pete: Probably falls under the Packaging element. Dale: Send this request to the CPP/A TC. Dale: May have issue with listing payload services in the Manifest, which currently uses URI to reference a CID, and assumes SOAP with Attachments. We've heard the complaint about being monolithic before; might rather keep it separate from the Manifest for modularity. Doug: It would only extend the Manifest, not change it substantially. Matt: Manifest is more for identification, rather than instructions. Dale: Is there a relationship between payload services and web services? Matt: Not really; view payload services as filters, rather than full-blown services. Jacques: We could look at the XML Signature model, in which the Signature block contains a series of transforms. Our services are similar in nature. ACTION: Matt to rework the Invocation section to make it XML-based, and also send proposal to CPP/A TC. 4. Identify owner to work with Jeff to perform the SOAP 1.2 & Manifest converstion Matt will work with Jeff, since his piece overlaps. Jeff will produce an initial cut. Pete will review and add details. 5. Update action list if required Approve minutes from last meeting? Need more time to review them. Approve next week. Doug has issue list ready to post, but instead will delay in order to make further progress on it. Matt will post outline of 3.0 document for review. 6. A.O.B. Jacques: We still have to talk about WS-Context. Jeff: We also had the issue of relying on WS-R; what about the case in which reliability is not needed? We can still use WS-R headers, but perform non-reliable messaging. Include on agenda for next week's call: Jacques' May 11 email re synchronicity http://www.oasis-open.org/archives/ebxml-msg/200405/msg00019.html 7. Next week call - Jacques to host? Jeff suggests extending call duration to 90 minutes from now on. Everyone seems OK with this.
