    Thursday July 10th at 1pm EDT is the Semantic Model teleconference. This
    week's Teleconference will be dedicated to IPP JobX. The document is
    available on the PWG server at
    (If someone could convert this to PDF I would appreciate it. I haven't
    found my copy of distiller to put on my new system yet.)

    The teleconference is 2 hours long. It will be run using phone and Webex.
    Anyone that does not yet have Webex installed should do that before
    Thursday. Information for the phone and Webex are included below. NOTE:
    New Dial in number and passcode

    The agenda for the Semantic Model teleconference is:
    1) Discuss the print-quality issue (see included notes below)
    2) Discuss the document-xxx-supplied changes in JobX
    3) Discuss the output-device resolution


    PS: Bob let me know if there is a problem hosting Webex.

    Print Quality Issue:

    Last Tuesday during the PWG/FSG meeting in Portland we had a discussion
    about the IPP print-quality attribute and FSG's desire to add two new
    values, "economy" and "fine", where "economy" is lower than "draft" and
    "fine" is higher than "high". After some discussion we all pretty much
    decided that it is not possible to add these new values to the already
    existing "draft", "normal", and "high" values because of the current
    definitions of the existing values (high is defined as the highest quality
    and draft is defined as the lowest quality). It also seemed like what FSG
    wanted was a way to specify print optimization and not additional levels of
    print quality.

    The FSG working group met today, and based on the input from last Tuesday's
    meeting, we would like to propose the addition of a new attribute, called
    print-optimize, that is defined as follows:

       print-optimize (type2 keyword)

          This attribute refines the value specified by the print-quality

          The standard keyword values are:

             'image': optimize for image clarity
             'photo': optimize for photo clarity
             'text': optimize for text clarity
             'text-and-image': optimize for both text and image clarity
             'save-toner': optimize for minimal toner usage
             'speed': optimize for printing speed

    We would appreciate your feedback on this proposal including suggestions for
    additional values.

    If this proposal looks good, we would like to propose that it be included in
    the JobX Spec. If the print-optimize attribute is approved by PWG by the end
    of August, then we can propose that it be added to the JDF 1.2 Spec that is
    being finalized in early September.

    Thank you for your time and feedback.

    Response to Print Quality Issue:

    I understand the desire to avoid violating the semantics of the IPP
    attribute - but adding these enumerations to print-quality does not feel as
    objectionable to me as splitting a single semantic concept into two
    different attributes. If this is the precedent we take for extending the
    semantic model, I'm worried that we'll end up with an increasingly confusing
    and complex. I would rather we take the minor hit and fix the high & draft
    definitions in the semantic model than create another ~equivalent attribute
    with a whole bunch of special semantic rules (e.g. - what should the service
    do if print-quality=high and print-optimize=save-toner?).
