SM> Updated Comparison of JDF FileSpec and corresponding IPP Document object available

The downloaded document starts out with the proposed JDF FileSpec resource
additions.  Then the second half is a side-by-side comparison of the JDF
FileSpec resource with IPP Document object attributes.  I've included the
changes to the specific IPP "document-format-details" member attributes from
the Thursday, 20-March-2003 telecon.  The document is available at:

This document contains proposed additions and clarifications to the JDF
FileSpec resource for JDF/1.2 and the corresponding IPP Document Description
attribute proposed for the IPP Document object extensions.  The reason for
showing both in the same document is to try to align the semantics where
possible.  Some of us believe that there will be significant interworking
between JDF and other systems, such as IPP.  Having the same values of
corresponding attributes will make gateways a lot simpler.  Note:  There is
no need for the names of the attributes to be the same.  The real gain is
for the values.
These proposals build on the proposals from Martin Bailey, Bob Taylor, and
Israel Viente in CIP4 and the proposals from Bob Taylor, Dave Hall, and
Peter Zehler in the PWG for inclusion in the IPP Document Object, PWG
Semantic Model and PWG Print Services Interface (PSI) which is a follow on
to Bluetooth.  The most recent version results from a telecon on March 21
with Craig Benson, Bob Taylor, Steve Hiebert, and Tom Hastings attempting to
accommodate all of the comments received in email.

Please send any comments.

I'm working on the full IPP Document object spec updating the agreements
reached on Thursday, March 20 telecon and will have it out on Monday, March
