I've extracted the edits that Don made at the IPP WG meeting in Tampa so
that the mailing list can see them regarding the "Internet Printing Protocol
(IPP): The 'ippget' Notification Delivery Method for Event Notifications"
out for IPP WG Last Call closing on March 26, 2001. These comments are
being treated as Last Call comments. Send any comments on these comments to
the entire mailing list.
1. In Table 2 - Attributes in Event Notification Content, When the '*' was
added to the MUST for printer-current-time why was it not a double asterisk
added to notify-user-data and a triple asterisk added to the others below
2. In section 6.2.1 notify-recipient-uri (uri), end of section, call out a
reference to Section 9 here which is the new section entitled "The IPPGET
3. In section 9.4 The IPPGET URL Scheme Character Encoding, change "host
name or host address part" to "scheme and host or host address part". Also
change 'path' to 'abs_path' to give:
The 'ippget' URL scheme defined in this document is based on the ABNF for
the URI Generic Syntax [RFC2396] and further updated by [RFC2732] and
[RFC2373] (for IPv6 addresses in URLs). The 'ippget' URL scheme is
case-insensitive in the scheme and host or host address part; however, the
'abs_path' part is case-sensitive, as in [RFC2396]. Code points outside
[US-ASCII] MUST be hex escaped by the mechanism specified in [RFC2396].
4. End of section 9.5.1 IPPGET URL Examples, MORE EXPLANATION OF THE
ALTERNATIVE URL FORMS (or a pointer to where it is explained) AND WHY TO USE
ONE OVER THE OTHER WOULD BE HELPFUL HERE.
5. In section 9.5.2 IPPGET URL Comparisons, SIMPLER EXPLANATION?
6. In section 11.2 Conformance for IPP Clients, why is the following
required for clients:
4. MUST convert the associated 'ipp' URLs to their corresponding 'http'
URL forms according to the rules in section 5 "IPP URL Scheme" in [RFC2910].

Title : Internet Printing Protocol (IPP): The 'ippget'
Delivery Method for Event Notifications
Author(s) : R. Herriot, C. Kugler, H. Lewis
Filename : draft-ietf-ipp-notify-get-02.txt
Pages : 30
Date : 07-Mar-01
The notification extension document [ipp-ntfy] defines operations that a
client can perform in order to create Subscription Objects in a Printer
and carry out other operations on them. A Subscription Object represents
a Subscription abstraction. The Subscription Object specifies that when
one of the specified Events occurs, the Printer sends an asynchronous
Event Notification to the specified Notification Recipient via the
specified Delivery Method (i.e., protocol).
The notification extension document [ipp-ntfy] specifies that each
Delivery Method is defined in another document. This document is one
such document, and it specifies the 'ippget' delivery method.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
