Here are the meeting minutes from the IETF46 meeting of the IPPEXT BOF.

Thanks to Don Wright for taking the notes.

Don gave me his draft a while ago, I am the one who have dragged my feet
getting the participants added. Blame me or the turkeys...

I have also uploaded the text at:


I realize that we still have problems with the slides, apparently my second
attempt was no better than the first one.
I will keep on trying to figure out a way of getting a readable file for
Acrobat 3...

Carl-Uno Manros kicked off the meeting at 2:15 PM.

- Review work to date
- Proposed Extensions

Carl-Uno Manros identified 3 areas of potential future activity:

1) IPP Notifications
2) Additional Operations for Operators and Administrators
3) Extensions for Advanced Production Printing

Carl-Uno raised a question on IETF's interest in #2 and #3 above.



- drafts of the notification work were listed and described in some detail
- several different methods of transporting notifications were identified

Drafts are: <draft-ietf-ipp-not-03.txt>

Josh Cohen discussed GENA, which is a general notification architecture and
currently an individual I-D.

New Operations:

- draft of the set 2 operations was discussed
- will be divided into 2 documents, 1 dealing with printer objects and the
dealing with device objects
- the plan is to be consistent with the Printer MIB

Draft is: <draft-ietf-ipp-ops-set2-00.txt>

Question: Is there a way to release jobs one at a time?
-- Already provided by IPP and the proposed extensions.

Question: What's happening with security on notifications? Could someone
page-by-page notifications to a large e-mail list and therefore spam a large
-- Possible and it will have to be addressed.

Comment: Does using HTTP open up a security hole on the client?
-- This will have to be addressed.

Production Printing:

- operation and attribute extensions for professional production printing
complex jobs

Comment: This kind of extensions is probably outside the scope of interest
the IETF. Keith Moore agreed.

The production printing parts will not be part of the charter of the IPP
extensions working group.

The proposed milestones for IPPEXT were reviewed.
Final version of these milestones will be included in the charter.

Carl-Uno reviewed where IPP is in general:

- IPP V/1.0 Experimental RFC
- Bake-offs, the second held in April 1999
- There are a number of products in the market already based on the 1.0
- The 1.1 Specs were handed to the IESG in the summer; they have not been
published as RFCs yet.

The meeting adjourned at 3:15 PM
