This Thursday at 1pm EDT is the Semantic Model teleconference. This week's
teleconference will be dedicated to IPP Jobx.  I will post the document
later today.  This review will prepare the document for the Face-to-Face.

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 remaining issue and reach consensus

The following issue came up during the Review of the JOBX specification on
June 4, which affects the Job Extension spec, the Document Object spec, and
the PWG Semantic Model spec.

For IPP there are the following Operation attributes that a client MAY
supply in a Print-Job or Print-URI operation for specifying Document
Attributes that do not have corresponding Description attributes defined
until the Document Object specification:

compression (type2 (keyword))
document-charset (charset)
document-digital-signature (type2 (keyword))
document-format (mimeMediaType)
document-format-details (1setOf (collection))
document-format-version (text(127))
document-message (text(MAX))
document-name (name(MAX))
document-natural-language (naturalLanguage)

The preceding attributes are attributes of a Document.  Therefore, unless
the Document object is implemented, it is not possible for a client to
completely determine what a client had submitted.  As a consequence, it is
also not possible for an application to completely archive a single document
job using the Get-Job-Attributes operation. Furthermore FSG is using these
attributes at the Job level in its APIs.  When implementing the Document
object, these same attributes can be supplied in the Send-Document and
Send-URI operation as well.  These attribute have slightly different
semantics at the Job level than they do at the Document level.

A solution for IPP JOBX (whether or not implementing the Document object)
would be to define corresponding Job Description attributes for these
specific operation attributes with the semantics that they are the defaults
for the all the Document objects in the Job (even single document jobs
created with Print-Job and Print-URI).  These new Job Description attributes
would be :
compression-default (type2 (keyword))
document-charset-default  (charset)
document-digital-signature-default  (type2 (keyword))
document-format-default  (mimeMediaType)
document-format-details-default  (1setOf (collection))
document-format-version-default  (text(127))
document-message-default  (text(MAX))
document-name-default  (name(MAX))
document-natural-language-default  (naturalLanguage)
These new attributes would be populated by the associated operational
attribute if supplied.  
The file for telecon is the pdf file:
NOTE: This file does not include the above proposal for the remaining issue.
However, given the time and my schedule I wanted to get something out.  If
possible I will get an update out later this week.  The main issue and
resolution proposal is explained fairly well above.
