    We've had a long thread of discussion about the need to indicate the version
    of a document format in a job submission along with its MIME type in JDF and
    IPP. In JDF this infomation is represented as attributes in the FileSpec
    resource. In IPP, the PWG Semantic Model (SM) and the Print Service
    Interface (PSI), the document format and versions are represented as
    Document Description attributes. In IPP the client submits these as
    operation attributes which the Printer copies to the corresponding Document
    Description attributes.

    Here is a quick summary to see if we are in agreement:

    1. Don't add stuff to the IPP Document object that hasn't been asked for,
    even though its being added to JDF FileSpec resource. So IPP will remain a
    subset of JDF. So while adding TransferEncoding (per Israel Viente's
    request), DocumentClass (to help distinguish fonts from other files), and
    some attribute for use with fonts to designate which organization they are
    coming from (which need work) so we don't need MIME types for fonts.

    2. The following list show the relationship between IPP Document object and
    the JDF FileSpec. In JDF, only ContainerSummary, IEEE1284DeviceID and
    FileFormatVersion are new. All of the IPP Document attributes are new
    except for document-format and document-natural-language:

    document-container-summary (collection) ContainerSummary
      which can contain:
      document-creator-application-name (name(MAX))
      document-creator-application-version (name(MAX))
      document-creator-os-name (name(MAX))
      document-creator-os-version (name(MAX))
      document-format (mimeMediaType)
      document-format-device-id (text(127))
      document-format-version (text(127)
      document-natural-language (naturalLanguage)
    document-creator-application-name (name(MAX)) Application
    document-creator-application-version (name(MAX)) AppVersion
    document-creator-os-name (name(40)) AppOS
    document-creator-os-version (name(40)) OSVersion
    document-format (mimeMediaType) MimeType
    document-format-detected (mimeMediaType) N/A
    document-format-device-id (text(127)) IEEE1284DeviceId
    document-format-version (text(127) FileFormatVersion
    document-natural-language (naturalLanguage)

    I'll have an updated spec for IPP Document object out by Monday AM and a
    corresponding FileSpec on Monday.

    I won't be addressing additional MIME types in these documents. That is
    separate.

    Tom
