Hi,
OK - two specs.
In UIF spec, we should talk about (I think) lowercase client and
server (which are much more accurate than unqualified Sender and
Receiver) or initiator and responder (generic protocol terms).
In IPP Fax spec, the term (job) Sender is COMPLETELY inaccurate
when describing that this Sender needs to query capabilities
from 'printer-uif-capabilities' with Get-Printer-Attributes.
The entity may decide to never send a job, because the printer
is not sufficiently capable.
In IPP Fax spec, I strongly object (even with definitions) to the
use of the Sender and Receiver for IPP client and IPP Printer object
(in RFC 2910/2911). It is called 'IPP Fax' - it's a profile of
behavior of the two basic IPP software entities.
Cheers,

I prefer the terms Sender and Receiver for the reasons Tom mentions, as long
as we define what we mean exactly by these terms in a "Terms Used" section.
I don't think we should use IPPFAX before the terms Sender or Receiver in
the UIF spec, as we are trying to keep UIF non-protocol-specific.

Ira is suggesting IPPFAX Server, instead of IPPFAX Receiver or IPPFAX
Printer. (We're all in agreement *not* to use "host").
However, to me a Server can act as a Sender or a Receiver, so I like the
terms Sender and Receiver, because they are more clearly *roles* that hosts
and servers can play. The conformance requirements of Sender vs. Receiver
apply to the role.

On the second issue, I believe the original issue from the minutes was
whether to use the IPP/1.1 terminology for IPPFAX Sender and IPPFAX
Receiver, which would be IPPFAX Client and IPPFAX Printer, not IPPFAX Host.
To me the term Host is much too vague. To me a Host could be a sender or a
receiver.
So I'm quite opposed to using the term "Host". Whether to continue using
the IPPFAX terms Sender and Receiver or go back to the IPP/1.1 terms of
Client and Printer is harder to decide. If we go back to the IPP Client and
Printer terms we would make it clear that the term Printer means the
software entity that accepts requests and returns responses, as in IPP, and
need not actually have any hardware associated at all. The advantage of the
term Receiver, is that no hardware is suggested by the name.
However, the problem with using the term "receiver" is that it affects the
names of some of the attributes ("receiver" vs. "printer"). Also we are
stuck with the IPP/1.1 terminology of Printer Description attributes and the
'printer-description' attribute group name used as a keyword in the
Get-Printer-Attributes request.
The attribute names affected are:
5.1 ippfax-sending-user-identity (text(MAX)) operation/Job
Description attribute 9
5.2 ippfax-receiving-user-identity (text(MAX)) operation/Job
Description attribute 9
5.3 ippfax-sender-identity (name(255)) operation/Job Description
attribute 10
5.4 ippfax-receiver-identity (name(255)) Printer Description
attribute 10
We should still keep the terms Sending User and Receiving User, but we could
change the terms Sender to Client and Receiver to Printer.
Then the attributes would be named:
5.1 ippfax-sending-user-identity (text(MAX)) operation/Job
Description attribute 9
5.2 ippfax-receiving-user-identity (text(MAX)) operation/Job
Description attribute 9
5.3 ippfax-client-identity (name(255)) operation/Job Description
attribute 10
5.4 ippfax-printer-identity (name(255)) Printer Description
attribute 10
Comments?

Subject: IFX> some UIF issues...thoughts anyone?
While revising the UIF spec, some issues have surfaced and it would be great
if we can generate some discussion on them:
1) The MIME type for UIF data.
From the IPPFAX teleconferences held on May 30 & June 6, there was
consensus to use "image/tiff; application=faxbw" and "image/tiff;
application=faxcolor". The primary argument for using these was that it is
the same MIME type used for Internet Fax, and so there would be less of a
conformance issue with an IPPFAX device serving as a gateway for Internet
Fax documents.
However...If we are going to make UIF a protocol-independent data
format (which was also agreed at the May 30 telecon), I do not think think
we should directly associate it with Internet Fax. Perhaps "image/tiff;
application=uif" would be a better compromise in that UIF would be made
independent of Internet Fax while existing TIFF readers can still do
something with the UIF data.
In addition, is it valid to use the same MIME type as Internet Fax
if the data requirements for UIF and TIFF-FX are not identical? (TIFF-FX is
more strict with resolutions and allowed image widths)
2) The use of the terms "Client" to mean the "Sender" and "Host" to mean the
"Receiver".
Is "Client" interchangeable with "Sender" and "Host" with "Receiver"?
Should we be using the more generic terms "Client" and "Host" instead of
"Sender" and "Receiver" in the UIF spec since the UIF spec is NOT
protocol-specific?
Does anyone have any thoughts on these issues?
Thanks,
John
