    Subject: PWG Events Schema and standard names

    Hi,

    Last week at the PWG Process telecon, I mentioned our
    discovery that there are four methods in PSI/1.0
    that reference the 'NotifyEvents' element (a member
    of the Subscription object) in the PWG Semantic Model.

    But, the Semantic Model has no IETF or PWG working draft
    content in it, including the former IPP Notifications
    spec.

    There are three alternatives (we decided on the third):

    (1) - Delete the PS's response parameter from
          RegisterTargetDevice for subscription to events;
        - Delete the Send[Printer|Job|Document]Notification
          methods entirely;
        [lost functionality in PSI/1.0 spec]

    (2) - Advance the entire IPP Notifications spec with
          the complex semantics of the Subscription and
          Notification objects to become a IEEE/ISTO PWG
          Candidate Standard;
        - Revise PWG Semantic Model to include these objects;
        [probably one calendar year - stalls PSI/1.0 spec]

    (3) - Develop a PWG Events schema that defines
          'NotifyEvents' as a union of 'PrinterEvents',
            'JobEvents', and 'DocumentEvents'
          (consider adding fine-grained events from
          Printer MIB alert list at the same time)
        - Develop an IEEE/ISTO PWG Standard Event Names
          Candidate Standard
        - Revise PSI/1.0 to reference the Events schema
          to be added to PWG Semantic Model/1.1
        [hopefully 3 to 6 months]

    WBMM has an immediate and pressing need for this same
    'NotifyEvents' element for their existing Action
    'SubscribeForAlerts' and their existing operation
    'SendAlert' (needs in-progress Alert schema).

    I volunteer to create this Events schema and (with help
    from someone MS Word literate) write the working draft
    for the companion PWG Standard Event Names spec.

    Alan - you may wish to schedule some Tuesday PSI telecons
    to review and advance this work. Bill Wagner agreed that
    we should also spend WBMM telecon time, but we have a lot
    of other (unrelated) new WBMM content to work on too.

    Comments?

    Cheers,
    - Ira
