I forgot to say that I would want to keep both parts in the PWG IPP Fax Working
Group. The only difference from what we are curently set up to do would be
1. Two specs - data and transport
2. Clear statements that the format is usable without the transport, that the
format is a required for the transport, that the transport might use other

Life always gets interesting when an essential "must have" overlaps
directly with "no way Jos
The motivation for "QualDocs" apparently embraced both sets of
requirements - the "IPP Fax" AND broader "driverless" printing goals. I
support Paul's recommendation to split the specification as an effective
way to address the (powerful but unique) semantics of IPP-FAX (legal
issues etc.) Still, I feel both efforts are essentially follow-on to IPP
and need to be remain coordinated to prevent rampant divergence.

Subject: IFX> Thoughts after first meeting
Firstly, thanks to all who attended the initial IPP Fax (as I must now
call it) meeting in Chicago.
The passionate (did I hear heated, even) debate was a good sign; people
this is important and we all have strong ideas about what should be
Ron Bergman has posted detailed minutes for the meeting (thanks Ron) but I
repeat here the major points.
1. The name was changed from Qualdocs to IPP Fax. Most people felt
not clear and did not translate well for non USA attendees.
2. The charter was updated and accepted. No major changes were made to the
charter except to specifically state the we were building on IPP. Tee
version is on the web site http://pwg.org/qualdocs/index.html.
3. We thrashed out what we meant by 'high bars' low bars' 'negotiated' ,
with regards to image parameters.
What did become apparent was a split in people's views about how this
is to be used. The FAX attendees saw this as a 100% FAX product - whereas
broader imaging attendees (printers, copiers, scanners) saw wider
having a standardised, negotiated image format (as well as Faxing).
The wider uses include things like copier to copier copying, network
ad-hoc printing, etc.
Specifically the debate came down to whether or not the transmitted
needed to be watermarked or stamped in some way. For the pure fax people
was a must, for the wider uses this would be a disaster. I am sure there
other divisions too. I had crafted the charter to allow for the wider uses
well as the fax case but no form of word crafting can get round this
divide. The solution I propose is that we split the spec into two pieces.
A) A common agreed image format with some form of negotiation / discovery.
can be used regardless of whether or not the transport is doing 'IPP fax'
not. We will end up specifying the rules associated with saying that you
'application/tiff-fx' as a document format.
B) A set of enhancements to IPP to get 100% into Faxing on the internet.
Includes identity exchange, security, watermarking, etc. We would make A a
Actually splitting might well speed things up (divide and conquer)
What do people think?
