Scribe : Krishna Sankar
Approval of minutes : Minutes approved
Review Action Items :
DONE 2002.05.23: GlenD to post email adding an issue: Are MEP's hard
coded in the spec, or can they be extended through
extensibility?
ASSIGNED TO JOYCE 2002.05.23: JeffM to write up rationale for
dropping operation overloading.
DONE 2002.05.23: Philippe, Jonathan, Waqar to work on getting the usage
scenarios published.
DONE 2002.05.30: Jonathan will send email to the group regarding attending
the FTF by phone.
DONE 2002.05.30: Prasad to raise an issue of spec inconsistency about
optional parts.
RETIRED 2002.05.30: GlenD to write up his ideas re: extensibility
F2F:
Tuesday will adjourn early and the host has graciously agreed for a tour of the tech lab 5 to 6
Maps are available in the web site as links from the logistics page
Dinner at Sunday, meet in the Novatel lobby, 4:00 PM
Jonathan : Propose any issues to be discussed at the f2f in the list.
Sanjeeva : Two issues to discuss - 1) WSDL specs based on SOAP 1.2 ? 2) Service type. Will post both in the mailing list
Telephone access: AT present no plans - equipment already spoken for. There is a possibility that the Arch WG would get a phone set up and if so, may be we could use that. Follow up with Chris/Heather on this.
Requirements Input : Still waiting. Three areas - requirements marked as drafts, response from the public list and the feedback from the arch WG.
Goal : To complete all and republish the document as our best guess requirement
Last minute questions : None
Usage Scenario : Published
Issues :
Start discussing issues now and also send them to the mailing list. Jonathan will schedule for the f2f.
Overloading operations : Now waiting for Joyce
Extensibility/Open Content Model:
Discussions on QName Vs URI, 'required' attribute,...
Some agreement appeared that element-level granularity is unnecessary. The wsdl:required attribute will likely be removed in favor of something like a global <wsdl:required-extensions> element. Will continue to discuss at FTF.
Action : Glen to write a proposal and detail the concepts. URI as a string or a namespace URI, distinguish between what would be machine understandable and what wouldn't. URI might not point to a machine readable document, but a human understandable content.
Extensible message exchange patterns :
Glenn summarized the issue. The idea is to have MEPs instead of message types. This will provide an inherently extensible system. The request-response MEP would be required.
This is not a move towards orchestration, but on the wire message exchange patterns.
Would WSDL MEPS and SOAP 1.2 MEPs be the same ? In all cases ?
General consensus : Good idea, need more time to think and analyze issues including SOAP 1.2 relationship.
Continue discussion at f2f.
ACTION: Glen to explain SOAP MEP as a presentation at f2f
Remove solicit-response and output-only operations? : related to MEP.
Action : Jeffrey to write proposal and discuss at f2f
service type : Sanjeeva working on a proposal. Deferred to f2f
Non-SOAP HTTP Binding :
Jeffrey : There are about 6 items. Not really important.
ACTION: Jeffrey to write summary and revisit in two weeks.
Should Operations permit alternate and multiple responses :
Originated by Prasad. Discuss at f2f.
portType extensibility : related to the extensibility proposal under discussion.
Revisit after the proposal is completed and make sure this is covered.
Other issues
Publishing issues to be discussed at f2f:
i) Name. WSDL 1.2 / Any other name ?
ii) Namespace : ask for a W34c namespace URI ?
Time and place of next f2fs :
Sep 9-11, Washington DC, hosted by DISA
Nov 11-14, Macromedia or Sun. East coast
Meeting adjourned early.
Best wishes for a safe travel and f2f
