    - Sept 5 telcon [3]
      Approved.

    - Sept 9-11 FTF [4]
      Approved.

      Minor concern about misquotes in IRC log.  Discussion on minutes

[25] http://www.w3.org/2002/ws/desc/2/04/f2fNovLogistics.html

RETIRED  2002-07-21: Jeffrey & Gudge to flesh out a proposal for
                     omitting operation from soap binding.

                     2002-09-19:  Part of the hoisting proposal.  Need to
verify
                     completeness in upcoming draft.

CONTINUE 2002-07-21: Don Mullen to write up
                     an issue on making the transport attribute 
                     match the SOAP binding framework. 

                     2002-09-19:  Action item reworded.

DONE [5] 2002-09-05: Deitmar to extract remaining questions/issues from 
                     [6] and sent out in a new email thread to be opened
                     as a new issue(s).


Face to face actions follow:

PENDING  2002-09-09: Sanjiva to redo part 3.2 of his binding proposal.

PENDING  2002-09-09: Gudge to check whether there is already an issue
                     against Part 2: can you define different 
                     encodingStyles for different children of 
                     soap:Body (message parts).

PENDING  2002-09-10: Steve and Gudge to write up the portType extensibility
                     proposal.
                     
                     2002-09-19:  Action item reworded.

PENDING  2002-09-10: Sanjiva to produce a proposal for equivalence of 
                     (at least) top-level components in the next couple 
                     of weeks.

PENDING  2002-09-10: Gudge; Jeffrey Schlimmer; Roberto et al to write
proposal 
                     to remove message and replace with complexType.

                     2002-09-19:  Action item wording agreed to.

                     Roberto stated the goal is to determine what it would
look
                     like if we use XML Schema constructs instead of message
                     constructs.  

DONE [7] 2002-09-10: Arthur to kick off thread on @element vs. @type,
                     perhaps by showing how to convert an existing 
                     @element into @type.

DONE [8] 2002-09-10: Arthur to write up direction and rationale to 
                     drop @use=encoded and post to wsdl wg public list. 

PENDING  2002-09-10: Gudge to provide summary of using xml schema to 
                     wrap other type systems at an appropriate level 
                     of abstraction.

PENDING  2002-09-11: Sanjiva to describe out/out-in for pub-sub. [I
                     think this should be pub-sub _without_ out/out-in.]
 
                     2002-09019:  Form a task force (Joyce, Sandeep, Igor,
                     Steve T, Sanjiva, Adi, Roberto, Amy) to prepare
presentation
                     about adding pub/sub as a first class citizen of WSDL
1.2.

                     Sanjiva will send a note to the list describing a
starting 
                     position and seeking comment.

PENDING  2002-09-11: Jeffrey and Don define TCP binding.

New Actions as of 2002-09-19:

         2002-09-19: Sanjiva will write a Java binding

         2002-09-19: Sanjiva provide updates on Use Scenarios document to
                     Architecture Group.  
                     Need to determine whether this activity should be in
the
                     architecture group or moved outside.

4.  FTF planning:

    Nov F2F:

2002-09-19:  No joint meeting time scheduled with the Architecture
             group at present.  Can schedule if needed.  Rooms
             available for 3 days of solid meeting.
 
             Meetings will be planned from Monday AM through Wednesday PM.

    Jan FTF.
 
2002-09-19: Sri Lanka or Sydney?  About 25 people stated they could
            attend in Sydney.  3 people stated they could not travel.
            Jonathan will poll working group to ensure that Sydney
            will work.  Host Art Hague, not member of working group.

            Alternatives if Sri Lanka or Sydney do not work out:
              Vancouver, BC [Dave Orchard]
              Toronto, ON  [Arthur Ryman]
              New York, NY [Sanjiva Weerawarana]

            Plan would be to meet week of January 14 or 21.  Need firm
            offers by next week (2002-09-19)

  Tech plenary March 3-7 in Boston, we could meet 3-4 or 6-7.

2002-09-19: Do we want a meeting in conjunction with Tech Plenary?
            General consensus is yes, some concern with only 2 days
            of meeting and conflicts with other working groups.

            Plan is to go forward with planning WG F2F at Tech Plenary.

--------------------------------------------------------------------
5.  Arch harvesting of WSDL [9].  Need reviewers.

2002-09-19:  Arch group is attempting to harvest some of our work.
             Who can take a look and see if they are taking good stuff
             from them.

             Jean-Jacques -- document looks reasonable.

             Pending:  Review next week. Would like input from more
individuals.

--------------------------------------------------------------------
6.   Requirements [10]
     Need to finish up and publish again.

2002-09-19: Table for one week.  Need information from Gudge on
            Semantic Web requirement.  

            Action:  Review document for 9/26/02 meeting.

--------------------------------------------------------------------
7.  New Issues
	WSDL and INLINE Schema Definitions [11]

2002-09-19:  Gudge had indicated new issues to be added. 

             Enumeration of potential issues: 
              - Disallow importing of schemas except via
              - No predefined types of elements added to an embedded schema
              - Schema embedded in WSDL must have target namespace.  Cannot
define
                names in the undeclared namespace.
  
              Follow-up left to the editors.

--------------------------------------------------------------------
8.  BindingType proposal from Kevin [12].
    Response from Jacek [13].

2002-09-19:  Jeffery raised some concerns:
             - new user/novice user will find it hard to understand
               where information should go.  Can be addressed by adding
               a new attribute 
             - data model for binding is inconsistent with other models.  
             - should we consider this with Sanjiva's proposal?
             - can we break this down into small issues that can be
considered
               separately?

             Jacek -- concerns were summarized well.  Reusable binding is
aim.
             This idea is probably 2.0 material and not 1.2.  

             Roberto -- Clarifying question:  The use of term binding type
             is confusing.  Port and port type have a clear relationship.
             This proposal doesn't have a clear mapping.  Binding & Binding
             type.  Kevin agrees that a better name would be useful.

             Is the group interested in continuing to pursue this action?

             Straw Poll says we should continue to pursue.
                Continue:  13
                Stop:       1
                Abstain:   11

             Kevin asks that anyone with particular issues or concerns let
             him know so he can attempt to address them.

             Revisit next week.

--------------------------------------------------------------------
9.  Issue 2: SOAPAction has been deprecated, as of SOAP 1.2 [14].
    Jean-Jacques proposal at [15].  Jacek's addendum at [16].

2002-09-19:  Jean-Jacques summary:  WG wanted something better then
SOAPAction.
             Want a more general method in WSDL.  Introduce new
             element <http:field> to the HTTP binding.  Also, introduce an
             equivalent <soap:field> element to the SOAP binding.

             Jacek -- proposed name change as well as noted that some
             transports do not need to have MIME fields, and most MIME
             fields will not have parameters.  Current proposal leaves
             to much room for inconsistencies. 

             Glen -- this relates to a proposal on properties [24], there
             is a general pattern we should consider. 

             Jonathan -- group needs to review the property stuff in more
detail.  

             SOAP Action can turn into a property.

             Do we need to make a late comment to the XML Protocol group?  

             ACTION:  Glen will look and see status of SOAP Actions.  Draft
             potential last call comment to XML Protocols Group.

--------------------------------------------------------------------
10. Issue 18: Default for transport of <soap:binding> [17]. Jeffrey's
proposal at [18].

2002-09-19:  This item was closed at 2002-09-05 teleconference:
             Resolution (per 2002-09-05 minutes):
                  Issue 18 to be closed per [18] to make the transport
attribute
                  mandatory for the <soap:binding> element.

                  Issue 28 still open and may be discussed at F2F if time
permits.

--------------------------------------------------------------------
11. Issue 28: transport='uri' [19]

2002-09-19:  Defer until after Glen's proposal.

--------------------------------------------------------------------
12. HTTP Binding Issues (6a, 41)
    Jeffrey recommends no change [20].
    Sanjiva is mulling this over [21].

    2002-09-19:  Waiting on Sanjiva -- need to introduce HTTP header
                 and / or cookie as part of binding.  Differ until after
                 Glen's proposal.

                 Should this issue be broadened to say support of all
                 features of the transport.  Again, Glen's proposal will
                 spur this conversation along.

13. Issue 25: Interaction between W3C XML Schema and SOAP Data Model 
    Gudge's explains at [22], Roberto's options at [23].
    Waiting for more detail in ACM?

    2002-09-19:  Waiting for Gudge to provide more detail/wisdom
                 on abstract component model.

14. A slice at a proposal for SOAP features/properties in WSDL [24].
    Glen Daniels

    2002-09-19:  Move up on agenda for next week, key to a lot of the
                 binding work.

                 Read proposal for next week.
