  • Next message: McDonald, Ira: "PS> Thoughts on Discovery for PSI"

    Apologies for missing Ira last week.

    PSI Working Group:
    *Alan Berkema *Gail Songer *Dave Hall
    *Jerry Thasher *Harry Lewis *Ted Tronson
    *Peter Mierau *Peter Zehler Paul Tykodi
     Bob Taylor Don Levinstone *Lee Farrell
     Don Wright *Kirk Ocke *Ira Mcdonald

    * = attendance

    06/04/02 Agenda
    1) review Target Device Identifier and Reference schema
    2) Spec updates with attributes?
    3) Review actions

    Minutes:

    1) Review Reference Schema

    passwd and User could apply to any of the "choice"
    elements Kirk will think about elevating these to be
    reference attributes instead of at the child element level.
    Ira mentioned the need for a security "certificate"
    attribute.

    Time attribute - discussion started around time zone and
    lead to -> should this actually be a duration time instead.
    Actual time should be handeled at higher application layers.
    Could even be detrimental at the reference layer if devices
    are out of sync.

    Talked about adding additional elements for e-mail
    Kirk to investigate IMAP RFC 2192, SMTP RFC 2368
    and POP3 RFC 2384

    2) Review psi specs.
    Decided to adopt the new methods:

    InvokeJobWithContentByReference
    InvokeJobWithContentByValue

    Except that we decided to remove the last_document paramater.

    This discussion raised the topic of event notification.
    Will PSI address this? Needs further investigation.
    IPP is strugelling with too many optional notfication methods
    need to scale this down if it will be used with PSI.
    Subscription for events can occuur
    at the:
    o Printer Level
    o Job level
    o Job page level, this (if included) should not use high latency methods.
    Also need to consider existing industry methods such as JMS

    0) Job Control Interface starting to stabilize

    Work Remaining Overview:
    1) Finalize reference and Target Device Schemas
    2) Attributes: PSI has Job, Document, and Processing (template)
    Need to help with and leverage the PWG semantic model attributes
    3) Discovery, PS and the target Devices a PS knows about?
    4) Revisit Target Device Interface
    5) Status code, hoping that this will also be part of the PWG
    semantic model for leverage
    6) Event Notification
    7) Security

    Finish all that and PSI is done :)

    New 6/11/02 Actions:
    1) Referenc schema work user name, passwd, certifiacte
    and e-mail elements.
    Owner: Kirk:
    2) Investigate original thouts on time attribute with Bluetooth folks
    Owner: Alan
    3) Examine Use Models for Job Control interface implemenation
    owner: Dave

    Thanks,
    Alan
