I have reviewed the new proposed standard and have two concerns with
respect to the "IPP Subset of CUPS Raster"
1. It was my understand that a IEEE ISTO PWG Standard must not be the
standardization of product or a specific company's implementation
a. Thus, there is a great need for a PWG IPP Image format or PWG IPP
Raster format; however, I believe that specifying it as a subset of the
specific open-source or vendor product is not in line with PWG standards
practices. This is not to say that is could not have a normative or
informative reference to a specific open-source or vendor product but it
should stand on its own with ties to a specific open-source or vendor
product. Also, it should not use attribute names or variables that are
identified with a specific open-source or vendor product.
b. I am aware of other entities that wish to use an established
format (i.e. CUPS Raster 2); but if PWG is going to standardize it, it
should be PWG entity.
2. The specific open-source or vendor product that is being discussed
is CUPS. So, the other concern with a standard that directly references
CUPS is that CUPS is licensed by/under Apple and GPL.
a. I have not heard or know that Apple has provided a Letter of
Assurance on the use by others for the use a subset of CUPS definition.
While, I believe that Apple would provide LOA upon request.
b. On the other, if any or part of the content PWG is proposing to
use from CUPS was/is part of CUPS that was/is under GPL before Apple's
ownership; then there is the question if GPL license applies. Major
print vendors may be at risk of either having to release their source
code that is associated with CUPS content or even being sued by GPL
proponents.

Subject: [IPP] New draft of IPP Subset of CUPS Raster (IPP
Raster)specification posted
All,
I have posted a new version of the IPP Raster specification at:
ftp://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippraster10-20110126.docxftp://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippraster10-20110126.pdfftp://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippraster10-20110126-rev.pdf
This version incorporates all of the feedback from the IPP telecon
including the rename from PWG to IPP...
