In IPP, PWG Semantic Model and PSI we have Job Template attributes with "sister" (supported, default and ready) Printer Description attributes. When discussing the purpose of a "Job Ticket" in the semantic model, we often refer to Job Template attributes as the "job ticket" as these carry production intent. By definition, when queried, Job Template attributes must return the value associated with each attribute during submission. Thus, there is no way to query a job (or document) and learn WHAT ACTUALLY HAPPENED w.r.t. any particular attributed (ex. copies). This is covered by the JDF job ticket but we have said JDF is too workflow oriented for (initial) inclusion into the PWG Semantic Model. I would like to propose a solution - the addition of a group of Job Description attributes referred to as "-actual". These could be extensions to the group of Job Progress attributes or a separate grouping of Job Actual (or "Job Completion") attributes. I know, in IPP proper, we don't have the notion of job "history" (the job "disappears" as soon as it has completed) so "actuals" would not be very useful. But in the semantic model and PSI we're trying to overcome this. To the extent that we are reluctant to embrace a full fledged job ticket, the addition of "-actual" attributes should go a long way toward providing much of the essential JT functionality that was previously missing for non-produciton environments. For example: <tt>+===================+======================+ | Job Template      |Job Description:Actual| |   Attribute       |   Value Attribute    | +===================+======================+ | copies            | copies-actual        | | (integer (1:MAX)) | (integer (1:MAX))    | +-------------------+----------------------+ | finishings        | finishings-actual    | |(1setOf type2 enum)|(1setOf type2 enum)   | +-------------------+----------------------+ | sides             | sides-actual         | | (type2 keyword)   | (type2 keyword)      | +-------------------+----------------------+ | number-up         | number-up-actual     | | (integer (1:MAX)) | (integer (1:MAX))    | +-------------------+----------------------+ | orientation-      |orientation-requested-| |  requested        |  actual              | |   (type2 enum)    |  (type2 enum)        | +-------------------+----------------------+ | media             | media-actual         | | (type3 keyword |  | (type3 keyword |     | |    name)          |    name)             | +-------------------+----------------------+ | printer-resolution| printer-resolution-  | | (resolution)      |  actual             | |                   | (resolution)         | +-------------------+----------------------+ | print-quality     | print-quality-actual | | (type2 enum)      | (type2 enum)         | +-------------------+----------------------+ </tt> ---------------------------------------------- Harry Lewis IBM Printing Systems ----------------------------------------------
