Paul Knight : Hi all,
John Storrie: Joining call.....
Paul Knight : Additional telephone numbers for calling into this bridge:
anonymous morphed into Michael B
Mike Giordano: mike G - open meeting
Mike Giordano: Ian - second
Mike Giordano: John - minutes from last minutes for approval
Mike Giordano:Enrico - Second
Mike Giordano: Proposal to look at Telecom Italia Use cases
Mike Giordano: second
Mike Giordano: propose Tommaso as speaker
Mike Giordano: second
Mike Giordano: 3rd contribution to the team
Mike Giordano:Enrico - considers this a telecom specific problem
Mike Giordano:Enrico - would like to see a protocol that to support event and publish and subscribe widely adopted and can work with intermediary
Mike Giordano: techical issue limiting business
Mike Giordano: first part of contribution is not a technical issue - market needs a commonly used set of standards
Mike Giordano: telecom operators need standardization to support pub/sub notification in market
Mike Giordano:Enrico - this limits business development for SOA/ Telecom services
Mike Giordano: Second part of notification use case - technical issue
Mike Giordano: the presence of intermediaries is an issue
Mike Giordano: establishing the call back address thru intermediary
Mike Giordano:Enrico - vendors are not happy due to specific customization required
Mike Giordano: before open the floor - vechenzo to add comments
Mike Giordano: second
Mike Giordano: Mike Brenner - couple of questions
Mike Giordano: It is assumed that the application does not know about the intermediary
Mike Giordano: BM
Mike Giordano: Mike Brenner says
Mike Giordano: SOAP 1.1 there is a concept of actors that are being traversed by the message
Mike Giordano: this issue should be handled by the application?
Mike Giordano: intermediary could enrich messaging with addressing information
Mike Giordano: this also could be handled by intermediary
Mike Giordano: for those cases where this issue needs to be handled by intermediary - this is a problem
Mike Giordano: other comments?
Mike Giordano: Fend Lui - this is a valid use case
Mike Giordano: Avaya has similar issues
Mike Giordano: currently there is a W3C web service resource access trying to standardize this
Mike Giordano: based on WS-Eventing mechanism
Mike Giordano: WS-Eventing provide a subscribe method
Mike Giordano: also provides you filter to events, cancel methods, 3rd for intermediaries, you need to specify endpoint reference which is the event sink.
Mike Giordano: FL - so this reference will allow event sink to propagate thru intermediary
Mike Giordano:Tommaso - point of clarification
Mike Giordano: FL - when you send subscribe request - you have to provide event sink but is not a part of WS Addressing header
Mike Giordano:Tommaso - Application sends request, passes information to provider thru reference - event sink address in the body
Mike Giordano:Enrico - this is work in progress
Mike Giordano: 6 to 12 months there may be a resolution
Mike Giordano: FL - right - its work in progress and these are very good use cases
Mike Giordano: FL - the W3C activity is ongoing and finalized by June
Mike Giordano: may take a year to become a standard
Mike Giordano: FL - thinks a lot of venders will drive this to a standard
Mike Giordano:Enrico - suggests a liaison with this group to finalize a standard to meet a requirement
Mike Giordano: MikeG - Seconds this open
Mike Giordano: Paul Knight - straight forward way to establish a technical committee to make establish this
Mike Giordano: PK - a general outline - the TC can propose and adopt the individual to facilitate this
Mike Giordano: PK - also possible for TC to establish a sub committee
Mike Giordano: PK - is fairly well described in TC process
Mike Giordano: PK - will bring it up in up later in the meeting
Mike Giordano: John Storrie - Any more discussion on the submission
Mike Giordano: Ian Jones - thinks the use case is showing issue thru intermediaries shows that the world is not point to point
Mike Giordano: IJ - we need a general purpose event notification issue
Mike Giordano: IJ – what is the relationship between event notification and fault and alarm notification in management
Mike Giordano: IJ - are they are the same thing?
Mike Giordano: Mike G - they may be the same issue but should it leverage the same infrastructure
Mike Giordano: JS - action item to have view of Event management and communications (functional) event notification
Mike Giordano: can leverage the same infrastructure but the ways the things are generated is different
Mike Giordano: The question is if we focus only on the infrastructure and ignore the type of events is a problem
Mike Giordano: Lucia - the issue can be dealt with at a higher level
Mike Giordano: Network management and interaction between mobile devices - WS eventing rich enough to support both
Mike Giordano: An infrastructure for passing events back and forth can only be used that classify events
Mike Giordano: JS - maybe we need to have small team to look at this
Mike Giordano: JS - is this a correct thing to do?
Mike Giordano: Do we need to scope event types
Mike Giordano: MB - maybe we should refocus on original problem ?
Mike Giordano: MG - Latency and ordering of events is extremely import issue for communications
Mike Giordano: MG - if standard is proposed that does not deal with these issue - is it useful in a communication context?
Mike Giordano: MB - not sure if we can start with anything at once!
Mike Giordano: MB - yes its an issue but it may be to large of an issue
Mike Giordano:Enrico - to facets of a problem
Mike Giordano:Enrico - we should go by steps
Mike Giordano:Enrico - Lets start with the lack of standards then address some of the facets of the problem
Mike Giordano: BM - if indeed the subscription mechanisms does not exist then this is the first problem that needs to be addressed
Paul Knight : Liaisons to the TC
An OASIS TC may desire to have a relationship with the working group or technical committee of another organization by having one or more persons act as liaison representative(s) between the two groups. The selection of the liaison and any invitation to other organizations to provide a liaison should be by vote of the TC. The selection of the liaison must be communicated to OASIS Management, and the liaison must be listed on the TC's web page. The TC may form a liaison subcommittee as required to help the TC coordinate its various liaison relationships.
- from the LIAISON POLICY - (not TC Policy)
Mike Giordano:Enrico - We should maybe seek to suppliment a new use case to identify latency, priority issue
Mike Giordano: JS - need to scope this to workable chunks
Mike Giordano: MG - vote to accept use case
Mike Giordano: JS - second
Mike Giordano: MG - any objections?
Mike Giordano: JS - motion for accept use case a and b notification use case
Mike Giordano: MG - second
Mike Giordano: any objections?
Mike Giordano: No objections - motion carried
Mike Giordano: Paul Knight - speak about liaison
Mike Giordano: PK - suggests we set up a WiKi
Mike Giordano: MG - Will check it out
Mike Giordano: MG - will get back to the group
Mike Giordano: IJ - F2F - week before conference call should be limited to specific submissions
Mike Giordano: JS - keep march 24th meeting and focus on agenda
Mike Giordano: JS - to 30 minutes
Mike Giordano: MG - who will be f2f
Mike Giordano: JS - who will have submissions (Nortel, Avaya, and Telecom Italia ....
Mike Giordano:Enrico will have a contribution before that
Mike Giordano: JS - aggregated policy for composite services
Mike Giordano: JS - MG will work with agenda of f2f
Mike Giordano: JS - will need input from group to put together with agenda
Mike Giordano: Chairs to contact Mary to set up working group relationships
Mike Giordano: Feng L - will update W3C Wu Chou
Mike Giordano: JS - Motion to close?
Mike Giordano: Paul - second
