As a result of all this, are we going to update the currently-existing "PWG
Standards" ( with the correct status?

Of the five standards:
- Three (5100.1, 5100.2, and 5100.3) are marked as "PWG Draft" but I
believe they have gone through only one Last Call and no vote.
- One (5100.4) is marked as a "PWG Trial Use Standard", and says to look at
the PWG Process to find out what that is, but the PWG Process document has
no mention of such a thing.
- One (5101.1) is marked as a "PWG Standard", and although I don't know
exactly how many Last Calls, votes, etc. it has had, I'm pretty sure it has
not followed the requisite steps to be called a "PWG Standard".

If we're going to have a process, and expect it to be followed, I think we
really need to look at these five and bring them into compliance.

So you are suggesting that the PWG names and steps are the same as the
IETF, which will help us all understand the PWG process better.  I think
this is fine.  And thanks for updating the PWG Process Document.

So we still need a name for the various versions of documents that lead up
to the Last Call.  I think that the current PWG process document uses the
term "PWG Working Draft".  So the template that I was working on for
IEEE-ISTO PWG standards should be for a "PWG Working Draft", not for a "PWG
Proposed Standard" or a "PWG Draft Standard".  I can make a second template
for the PWG Proposed Standard which just changes the few items from "PWG
Working Draft" to "PWG Proposed Standard".  OK?

This terminology and PWG steps map nicely and has a similar sound to the
IETF equivalents.  The equivalents to the "PWG Working Draft" is the IETF

So the complete PWG process is:

PWG Working Draft - many each with a distinguishing decimal version number
(0.1, 0.2, 0.3 ... 0.9, 0.10, 0.11, 0.12 ...) leading up to Last Call (1),
Last Call (2), or Last Call (3).

Last Call (1) + Vote -> Proposed Standard Version 1.0.  If it is revised,
then repeat at this level with a new version number, either 1.1, or 2.0.

Last Call (2) + Vote + Steering Committee -> Draft Standard Inherits the
version number from the last Proposed

Last Call (3) + Vote + SC + General Acceptance and Interop -> Standard
Inherits the version number from the last Proposed

And the comparison of the PWG Process with the IETF Process is:
PWG Process -- IETF Equivalent
--------------------     ----------------------
PWG Working Draft -- Internet Draft
PWG Proposed Standard -- IETF Proposed Standard
PWG Draft Standard -- IETF Draft Standard
PWG Standard -- IETF Standard

and the Last Call requirements are the same for each step as well.

The one difference between the PWG process and the IETF process, is that
you are only requiring interop for going from Draft standard to Standard.
I think this is a mistake, since one of the purposes of the interop is to
fix the document.  So I'd suggest adding back interop to going to Draft
Standard as well.  And that we do interop after a Proposed Standard is
approved and decide whether to have another version of the Proposed
Standard or whether we can go on to Draft standard.

      I don't think it is healthy to relate our process steps to IETF. This
      is an unfortunate artifact. I re-read and feel the doc is pretty
      Last Call (1) + Vote -> Proposed Standard
      Last Call (2) + Vote + Steering Committee -> Draft Standard
      Last Call (3) + Vote + SC + General Acceptance and Interop ->
      I'm sure there is room for clean-up. I will try to remove references
      to IETF and add clarification where necessary and repost the document

      Our PWG Process document needs some work.  There is confusion about
      different steps in the PWG standards process.  Dennis Carney and I
      the current process document, available as .pdf from the Chair's

      In fact, the Tab at the top of the Chair's page gets you to a
      version of the process document
      than the first process document described as:
      Review the Printer Working Group Standards Process document  (pdf)
      The latter fixes typos in the former with revision marks.  The latter
      attempts to map the PWG documents to the IETF documents by saying:

      PWG working group charter is equivalent to an IETF working group
      PWG Proposed Standard maps to an initial IETF Internet Draft
      PWG Draft Standard maps to an IETF RFC Proposed Standard.
      PWG Standard maps to an IETF RFC Draft Standard.
      There is no PWG equivalent to the IETF Standard.

      The intent of the PWG process was to skip one of the hurdles that the
      has.  So the first Last Call would be to transition a PWG Proposed
      to a PWG Draft standard.  We thought that only one round of
      tests were necessary (though more could be held) after reaching PWG
      Standard status in order to transition to PWG Standard.

      However, reading the text of the process document (sections 3.3, 3.4,
      3.5) and the table at the end, Dennis and I agree that it isn't very
      whether the Last Call is needed to get to a Proposed Standard.   If
      so, then
      the predecessor to a Proposed Standard is a series of "PWG Working
      (not versions of a PWG Proposed Standard), according to section 3.3
      and the
      Table at the end.  And then another Last Call to get to a Draft
      And a third Last Call to get to a PWG Standard.  If so, then we would
      the same number of stages in the PWG and the IETF.  If we did, what
      do we
      call the versions of the document before the first Last Call?  These
      correspond to what the IETF calls Internet-Drafts.

      The current 5100.1, .2, and .3 say PWG Draft Standard, because they
      gone through their first Last Call, but have not had interoperability

      The Media Standard is silent, so the Media standard looks like it is
      a PWG
      Standard, though no interoperability tests have taken place.

      Anyway, the IPPFAX and PDF/is documents are ready for a Last Call.
      just not sure what to call the specifications before the Last Call is
      PWG Working Drafts to become a PWG Proposed Standard
      or versions of a PWG Proposed Standard to become a PWG Draft

      Several people ought to take over the PWG Process document and work
      after we agree as to how many steps and Last Calls we want.

      The last "Last Call" incorrectly requested that the two documents in

      PDF and Word versions of the drafts are posted at the pwg web site


      The Last Call notice follows:

      This is a formal request for final within the IPPFax Working Group in
      to move two documents to Proposed Standard. These documents are "PDF
      Image-Streamable Format - PDF/is"  and the "IPPFAX/1.0 Protocol".
      These are
      IPP Working Group products, which have been discussed since early
      2001. It
      is the intent, once all comments have been address, to progress these
      documents to Proposed Standard.

      Last Calls are for a minimum of 2 weeks. The period for the Working
      comments will close on Dec 20, 2002(US Pacific time reference).

      The relevant documents are:

      IPPFAX is used to provide a synchronous, reliable exchange of image
      Documents between clients and servers.  The primary use envisaged of

      The IPPFAX/1.0 protocol is a specialization of the IPP/1.1 [RFC2911],
      [RFC2910] protocol supporting a subset of the IPP operations with
      conformance requirements in some cases, some restrictions in other
      and some additional REQUIRED attributes.  The IPPFAX Protocol uses
      'ippfax' URL scheme (instead of the 'ipp' URL scheme) in all its
      operations.  Most of the new attributes defined in this document MAY
      supported by IPP Printers as OPTIONAL extensions to IPP as well.  In
      addition, IPPFAX/1.0 REQUIRES the support of the IPP Event
      mechanism [ipp-ntfy] using the 'ippget' Pull Delivery Method

      An IPPFAX Printer object is called a Receiver.  A Receiver MUST
      support at
      least the PDF/is S Profile as specified in [ifx-pdfis] which is
      defined for
      the 'application/pdf' document format MIME type .  A Print System MAY
      configured to support both the IPPFAX and IPP protocols concurrently,
      each protocol requires separate Printer objects with distinct URLs.
