Hi folks, Monday (5 February 2001)
I've just sent a new version of 'IPP: IPP URL Scheme' to the
Internet-Drafts editor and posted a copy on the PWG server in the
directory 'ftp://ftp.pwg.org/pub/pwg/ipp/new_URL/' in the files:
draft-ietf-ipp-url-scheme-01.txt (February 2001)
draft-ietf-ipp-url-scheme-01.pdf (PDF w/ line numbers of '.txt')
The substance of this document is in five pages, starting at page 5 (see
the change log below). Carl-Uno Manros (IETF IPP WG chair) wants to
discuss this document at the IETF 50 Plenary in Minneapolis in March.
Comments?
Cheers,

Appendix X - Change History
[To be deleted before RFC publication]
5 February 2001 - draft-ietf-ipp-url-scheme-01.txt
- revised section 4.1 'IPP URL Applicability and Intended Usage' to
clarify that a given IPP URL MAY identify an IPP Printer object or
an IPP Job object, per request of Tom Hastings;
- revised section 4.5 'IPP URL Scheme Syntax in ABNF' to define IPP
URLs consistently with section 3.2.2 'http URL' of HTTP/1.1
[RFC-2616], per request of Tom Hastings;
- revised section 4.5 'IPP URL Scheme Syntax in ABNF' to clarify that
IPP URLs may reference IPP Printer objects, IPP Job objects, or
(possibly other future) IPP objects, per request of Bob Herriot;
- added section 4.5.1 'IPP URL Examples' to supply meaningful
examples of IPP URLs with host names, IPv4 addresses, and IPv6
addresses, per request of Tom Hastings;
- added section 4.5.2 'IPP URL Comparisons' to define IPP URL
comparisons consistently with section 3.3 'URI Comparison' of
HTTP/1.1 [RFC-2616], per request of Tom Hastings;
- revised section 5.1 'Conformance Requirements for IPP Clients' to
clarify that an IPP Client MUST convert IPP URLs to their
corresponding HTTP URL forms according to section 5 'IPP URL
Scheme' in [RFC-2910], per request of Tom Hastings and Bob Herriot;
- revised section 5.1 'Conformance Requirements for IPP Clients' and
section 5.2 'Conformance Requirements for IPP Printers' to clarify
that IPP Clients and IPP Printers SHOULD interoperate with IPP/1.0
systems according to section 9 'Interoperability with IPP/1.0
Implementations' in [RFC-2910], per request of Carl Kugler;
- revised section 5.2 'Conformance Requirements for IPP Printers' to
clarify that an IPP Printer MUST listen on (IANA assigned
well-known) port 631, unless explicitly configured, per request of
Michael Sweet;
- revised section 5.2 'Conformance Requirements for IPP Printers' to
clarify that an IPP Printer SHOULD NOT listen on ports other than
(IANA assigned well-known) port 631, unless explicitly configured,
per request of Don Wright;
- revised section 6 'IANA Considerations' to clarify that the sole
purpose of the entire document is IANA registration of the "ipp"
URL scheme;
- deleted Appendix A 'Registration of IPP Port' as unnecessary (port
is already registered);
- deleted Appendix B 'Registration of MIME "application/ipp" as
unnecessary (MIME registry has recently caught up to RFC 2910);

Abstract
This document is a product of the Internet Printing Protocol Working
Group of the Internet Engineering Task Force (IETF). Comments should
be submitted to the ipp at pwg.org mailing list.
This document is intended for use in registering the "ipp" URL scheme
with IANA and fully conforms to the requirements in [RFC-2717]. This
document defines the "ipp" URL (Uniform Resource Locator) scheme for
specifying the location of an IPP Printer, IPP Job, or other IPP
object (defined in some future version of IPP) which implements the
IPP/1.1 Model [RFC-2911] and the IPP/1.1 Protocol encoding over HTTP
[RFC-2910] or any later version of IPP. The intended usage of the
"ipp" URL scheme is COMMON.
The IPP URL scheme defined in this document is based on the ABNF for
the HTTP URL scheme defined in HTTP/1.1 [RFC-2616], which is derived
from the URI Generic Syntax [RFC-2396] and further updated by
[RFC-2732] and [RFC-2373] (for IPv6 addresses in URLs). An IPP URL
is transformed into an HTTP URL according to the rules specified in
section 5 of the IPP/1.1 Protocol [RFC-2910].
