SRT: Given the problems with file formats and then the virus storm the agenda has only turned up today. This means we (the chairs) fall foul of the 24 hour rule. Therefore I would like to hear if there are any objections to proceeding with this meeting on the basis that the agenda was not published 24 hours prior to the meeting.
SRT: Hearing no objections the meeting will proceed.

Nothing further to report
Nothing further to report
SRT: Model overview document: Ask for questions.
MM: Does transaction = choreography transaction?
Burdett: Related to recovery. Chor describes sequences of messages exchanged related to a transaction. Look at Section 3.0.
Burdett: Multiple transactions within a choreography could occur.
Burdett: Each recovery units are defined as separate choreographies.
DB: Let's try to re-explain what we mean by txn.
MM: Issues or lack of understanding is in lines 234 - 238
MM: Are u seeing txns only in the terms of the choreography?
DB: Yes we are.
MM: Then you need to make this clear. Because there is history behind the notion of txn and therefore it needs to be made very clear as to what you mean.
MM: I'd like to get more detail on "import"
DB: Our current "import" is not something we are totally happy with.
MC: I would suggest that what you should use to extend or refine needs to use a diff mechanism. Rather than lexical inclusion.
SRT: Return to Model Overview in next conference call along with reqts document.
SRT: Bring F2F issues to the call 3 February 2004.
SRT: Need team to review and comments.
NEW ACTION: Team to review the Model Overview prior to next meeting. Martin: New use cases may impact Model Overview.
Burdett: Auction use case as well.
Burdett: Can we get auction use case in reqts document?
SRT: Identify reqts not listed in the reqts document (that may be in a use case such as the Auction one).
Chapman: Keep number of use cases at a premium.
SRT: Need to make sure reqts identified in multi-party use case.
Note: M.Martin provided some suggestions for functions that need to be expressed in requirements' ease (sent to list today).
Burdett: Is more than one participant in a role handled? Chapman/SRT: Yes.
SRT: Liaison reports - Globus announcement?
SRT: WS-ResourceFramework announcement
SRT: OGSI retracted attribute reqts.
SRT: Specifications are not in a standards body.
Austin: Sun's representative has raised this issue about standards' body submission to GGF.
SRT: What can we do to make an impact, to support our work? Austin: WSA has addressed provisioning and resources.
Chapman: Need to explore at a chairs' level.
SRT: Look at WS-Agreement; choreography added value.
Chapman: BPEL status response?
M.Martin: Fell to the chairs to respond.
Attributes in WSDL2.0 (see action above)
Corda: WSDL 2.0 attributes. Grid not interested in pursuing attributes; use WS-RF.
Corda: Attributes were not a strong point for WSDL 2.0 and they may not be pursued.
SRT: Stateful aspects - Is this how we should use the attributes? Should we base our work on functions outside of a standards body.
Austin: Can we reference a non-standard or a specification under development in a standards body.
Yves: Can only reference if non-normative.
SRT: What did attributes give us? Approach GGF and ask their intent. Austin: Ask WSD for comment.
SRT: WSD will drop attributes.
Austin: Will we be the only ones that may complain?
Chapman: Do we have a need?
Burdett: Concrete choreography may need to reference or describe attributes. Have not reviewed to formalize this idea.
Corda: Attribute is not a property.
Corda: Attributes are about how to manage, inquire about state.
SRT: Attributes are like instance variables.
Chapman: Observable variables.
SRT: Need to provide capability to GET/SET for that variable if no WSD attributes.
Austin: Are we putting functionality into a proprietary forum? Chapman: Architectural issues are under discussion about identity models.
SRT: Related to binding of a web service to an identifiable instance? Chapman: Yes.
SRT: Enforce consistency across multiple identifies.
Chapman: Need to understand in choreography.
Chapman: What is the state?
Corba: WS-RF overlap to WS-CAF?
Corba: WS-Context may be relevant to choreography.
Corba: Can concentrate on them.
SRT: No reason/strong case identified for WSD attributes. Case identified for GET/SET where web services need to consolidate state to make it observable.
SRT: Close issue and allow WSD to take action.
Relevance of WS-Agreement
