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

<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">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.</span></font></p>

<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Hi Glen,<br>
<br>
With respect to 'fast tracking' of PWG Raster spec, note <br>
that the status phases Initial/Interim/Protoype/Stable must <br>
occur, per PWG Process/3.0.<br>
<br>
Except for waiving the PWG Process/3.0 requirement<br>
for a PWG Last Call to span a PWG face-to-face, there<br>
is little the PWG Steering Committee can do to 'fast<br>
track' this spec.<br>
<br>
And during the Prototype phase an actual prototype of <br>
substantial amounts of the base spec must be performed, <br>
reported on, and reviewed by the IPP WG.<br>
<br>
For comparison, PDF/is had *every* required and <br>
optional field prototyped. Wire formats need to be<br>
very stable before adopting them.<br>
<br>
I can't speak to Mike Sweet's editing priorities, but the<br>
main IPP Everywhere (profiles) and IPP JPS3 specs<br>
are high priority for their Cloud Imaging WG and MFD<br>
WG impacts.<br>
<br>
Cheers,<br>
- Ira<br>
