Hi Glen,
There is no specific duration for the document status phases.
Both the WG last call and PWG Last Call can't reasonably be
shortened. The time consumed is often *after* one or the other
last call, while the editors update the document and the WG
reviews those changes.
The scope of a SINGLE prototype (not an interoperability test)
is the choice of the implementation. But the PWG SC took a
conservative view with PDF/is (prototype every field) and the
IPP Fax WG followed through on that. In that case, Rick Seeler
(Adobe) tested that the sample PDF/is documents could be
correctly displayed by Adobe Reader as well.
A PWG Raster prototype could be fairly easily based on the
existing open source code for CUPS, I suspect.
The interoperability tests (between vendors) normally are only
*after* the PWG Candidate Standard is approved and required
for advancement to full PWG Standard document status.
Cheers,
- Ira

While I understand your comments on fast tracking, is there a "specific"
duration to each phase / process? So, I did not mean to change the
process but to encourage shortening it.
Can you help me understand the "scope of a prototype"? In this case,
the scope of the technical content is very small but I still assume that
the process steps can not be dropped.
Having just a source provider of the PWG raster is not interoperability.
I personally do not know of a printer that can read CUPS raster xxx or
one that could be modified to read a subset. So is emulation of a
printer ok? I also assume for interoperability, there must be two
independent developments.

Hi Glen,
With respect to 'fast tracking' of PWG Raster spec, note
that the status phases Initial/Interim/Protoype/Stable must
occur, per PWG Process/3.0.
Except for waiving the PWG Process/3.0 requirement
for a PWG Last Call to span a PWG face-to-face, there
is little the PWG Steering Committee can do to 'fast
track' this spec.
And during the Prototype phase an actual prototype of
substantial amounts of the base spec must be performed,
reported on, and reviewed by the IPP WG.
For comparison, PDF/is had *every* required and
optional field prototyped. Wire formats need to be
very stable before adopting them.
I can't speak to Mike Sweet's editing priorities, but the
main IPP Everywhere (profiles) and IPP JPS3 specs
are high priority for their Cloud Imaging WG and MFD
WG impacts.
Cheers,
- Ira

Epson would like in endorse the IPP working group's fast tracking of the
PWG/IPP raster specification / standard. Epson would like to further
encourage and endorse the PWG Steering committee in approving a (very)
fast tracking of the of PWG/IPP Raster specification / standard.
Epson supports the currently proposed format of the raster format
provided that the format is "streamable" in order to eliminate the need
for printers to provide buffering of full pages.
If the format has a REQUIRED color space, and Epson is not proposing
that there should be a REQUIRED color space; then Epson would like to
propose and support 24-bit sRGB
