August 2004 f2f minutes:http://lists.w3.org/Archives/Member/member-ws-chor/2004Aug/att-0007/August_2004_f2f_-_0.txt 

SRT - We will review this before accepting

SRT: Did we adopt the working draft? 

Chapman: I think we deferred. 
SRT: (Note 1) No decision to endorse as a working draft. 

Nick - whether we can do an assignment inside the interaction, atomically? 

SRT: (Note 2) It is unclear what was resolved. Place note 'See further discussion below.' 

People generally write WSDL the first way, not the second 

SRT: (Note 3) What are these ways? 

Kavantzas: This is way WSDL is used (such as solicit-response). 

SRT: Can we make it clear? 

SRT: Will correct in minutes. 

SRT - m/b good for type system to tell us that a race condition exists 

SRT: (Note 4): Is this a requirement? 

Martin: Does this put additional conditions on the language? 

SRT: A type system can issue warnings such as a race condition that can then be dealt with. 

SRT: Do we want to relax? 

Kavantzas: Is this a requirement for language, type system or a tool? 

SRT: Type system would record its detection and manifested in a tool. 

Chapman: Raise as an issue. 

NEW ACTION: SRT raise an issue on type system and warnings. 

Martin - i propose changing 'free' to 'alias' 

SRT: (Note 5) This relates to perform. Was it adopted? 

Chapman: Nick raised an issue. 

Yoko has joined #ws-chor 

Kavantzas: No decision was made. 

Fletcher: Place in minutes. 

SRT: F2F minutes passed subject to corrections above.

Action Items
-----------------

ACTION:  to look at element choreography notation to see how we may be able to roll up transaction features into it. (TF, 0525, 0601, 0615, 0629, 0706, 0713, 0720, 0806)

Transaction features: Fletcher - Not much happened in the meeting. Furniss still analyzing. 

SRT: Close action? 
Fletcher: Agreed. 
SRT: Close action with understanding it could be reopened when Choreology provides a new proposal. 
SRT close transaction features action. 

Action closed


ACTION: Take the TWIST example we're working on, add part of the flow what can go wrong, see what happens when things go wrong.  We can see in front of us the choreography being executed, what we do today with current language, what we can do with transaction. Steve is starting to add exception handling.  Nick and Steve have corresponded on "perform" which revealed some errors in the specification to be corrected. (SRT, 0525, 0601, 0615, 0629, 0706, 0713, 0806)  

TWIST: SRT - Still pending responses; impacts examples. 

IN PROGRESS

ACTION: We need to include an explicit mechanism for describing priority in a choice. (GB, 0713, 0806)

PRIORITY IN A CHOICE: SRT - Proposal submitted at F2F. Close action. 

CLOSED

ACTION: Martin to do an UML model (MC, 0806, 0831)
Ongoing, probably better logged as an issue.
NEW ACTION: Chapman log UML model as an issue. 

Closed

ACTION:  Editors to update perfrom as follows: 1) alias -> bind, 2) rule added to perform: the free variable must have free set to true in its definition, 3) rule added to variable definitions: variables with free set to true are required to be be bound in a perform in before they can be used. (ED, 0806)


 Kavantzas - Done. 
Kavantzas: Still must be reviewed. 

Closed


ACTION: Editors to change last bullet before section 1.4: change "Compatibility with other Specifications", "Specification Composability" (ED, 0806)

EDITORS 1.4 CHANGE: Kavantzas - Done. 

Closed

ACTION: Editors change last section in section 1.2 - reverse change in latest editor's draft - change "interoperability and interactions required to ensure conformance between services within one business entity" to ""interoperability and interactions between services within  one business entity" (ED, 0806)


EDITORS 1.2 CHANGE: Kavantzas - Done. 

Closed


ACTION: SRT to raise MEP extensibility problem with the WS-CG (SRT, 0806, 0831)

CG call next week.

SRT - log as an issue? 

Closed

NEW ACTION: Ritzinger to log as issue the need for need InputChannelVariable, OutputChannelVariable, FaultChannelVariable.

ACTION: We need proposals for requirements for rules governing endpoint generation both in the absence and presence of WSDL (OPEN, 0806)

NEW ACTION: Ritzinger  to log as an issue proposals for requirements for rules governing endpoint generation both in the absence and presence of WSDL.

Kavantzas - Done and must reviewed. 

Closed

ACTION: Steve to reissue the challenge to remind the group to respond; SRT will formally reissue it to Jean-Jacques (SRT, 0806)

SRT - Issued to Kavantzas and Dubray.

SRT: Maybe should switch actions to open issue and then do analysis. 
SRT: Logging in Bugzilla is only a record; whether we can do is TBD. 
Kavantzas: We can't do WSDL 1.1 if it is not BP based? 
Chapman/SRT: Correct - need analysis.
