Document Writeup for Working Group Documents
As required by RFC 4858, this is the current template for the Document Shepherd Write-Up.
Changes are expected over time. This version is dated 24 February 2012.
(1) What type of RFC is being requested (BCP, Proposed Standard,
Internet Standard, Informational, Experimental, or Historic)? Why is
this the proper type of RFC? Is this type of RFC indicated in the
title page header?
Experimental RFC is requested, and indicated in the header.
Note: see item (6) ***
(2) The IESG approval announcement includes a Document Announcement
Write-Up. Please provide such a Document Announcement Write-Up. Recent
examples can be found in the "Action" announcements for approved
documents. The approval announcement contains the following sections:
This document proposes a method to publish and "locate" OPENPGP keys
inside the DNS. The goal of this approach is to make it easier to find
OPENPGP keys for email addresses. The document defines a "method" to
convert email-addres into a special normal form. that is limited but
is expected to cover many cases. The OPENPGP DNS record specified has
been allocated by an Expert Review.
The method of mapping email addresses into the normal form has gone
through number of revisions based on feedback from WG participants and
email community. No one claims this is a perfect solution but good
solution for the particular problem space, where the sender to an
email has a "good" idea what an email address of the receipient
is. This protocol can be described as oppertunistic OPENPGP key
discovery. This is not a replacement service for PKGP servers but a
Working Group Summary:
The main issues that the WG has discused are
a) is it a good idea to publish email addresses in DNSSEC signed zone?
b) is the role of the nomalization from strictly a normalization or an
obfuscation as well?
The consensus of the WG is that as the publicaion is by the zone owner
it is an opt-in policy, there is no requriement for adoption thus the
issue need to be addressed in the light of each organizations
polices, i.e this is not a protocol issue.
The second issue there is a strong consenus that the purpose of the
normal for is only to map email addresses into a DNS label that is
valid in all implementations.
The working group consensus is strong about advancing this document.
Early version of this document went through DNS expert review before
the DNS RR type was allocated. The editor has been real good at
working with people to address textual and techical issues.
There are number of implemenations of this protocol and some
deoployment where organizations have placed over 1500 keys online.
More review from email community is welcome but until the email
community proposes a better form of normalization rules for email
addresses this is the best we can do.
Who is the Document Shepherd? Who is the Responsible Area Director?
Document Sheperd is Olafur Gudmundsson
Responsible AD is : Stephen Farrell,
(3) Briefly describe the review of this document that was performed by
the Document Shepherd. If this version of the document is not ready
for publication, please explain why the document is being forwarded to
DS has read every version of the document, and worked with the editor
in addressing isuses. A extensive working group last call was
conducted, along with with a session at a DANE meeting where people
from the email community had a frank discussion about the issues and
scope of the document. This document has advanced as far as it can
inside the WG and pubishing as Proposed Standard is the the desire of
(4) Does the document Shepherd have any concerns about the depth or
breadth of the reviews that have been performed?
(5) Do portions of the document need review from a particular or from
broader perspective, e.g., security, operational complexity, AAA, DNS,
DHCP, XML, or internationalization? If so, describe the review that
More review from email community will not hurt, but unless they have
an sudden insight as how to "cannonize" email address this is the best
we can do.
(6) Describe any specific concerns or issues that the Document
Shepherd has with this document that the Responsible Area Director
and/or the IESG should be aware of? For example, perhaps he or she is
uncomfortable with certain parts of the document, or has concerns
whether there really is a need for it. In any event, if the WG has
discussed those issues and has indicated that it still wishes to
advance the document, detail those concerns here.
There are are two issues that have been raised over and over again.
A. Do not publish email addresses in the DNS.
B. You are not guaranteed to find the key of the actual person you
want to send signed/encrypted email to.
Both of these issues have been refuted and as publication is optional
A. does not realy apply. For B. there conversion techique is has got
extensive input and improved based on that. There is not much more we
can do at this point to address it.
Some people have said that they would be more comfortable with the
document published as Experimental. The working group requests
publication as Standards Track but can live with Experimental status.
(Update: we changed to experimental.)
(7) Has each author confirmed that any and all appropriate IPR
disclosures required for full conformance with the provisions of BCP
78 and BCP 79 have already been filed. If not, explain why?
No IPR filed
(8) Has an IPR disclosure been filed that references this document? If
so, summarize any WG discussion and conclusion regarding the IPR
No IPR filed
(9) How solid is the WG consensus behind this document? Does it
represent the strong concurrence of a few individuals, with others
being silent, or does the WG as a whole understand and agree with it?
(10) Has anyone threatened an appeal or otherwise indicated extreme
discontent? If so, please summarise the areas of conflict in separate
email messages to the Responsible Area Director. (It should be in a
separate email because this questionnaire is publicly available.)
(11) Identify any ID nits the Document Shepherd has found in this
document. (See http://www.ietf.org/tools/idnits/ and the
Internet-Drafts Checklist). Boilerplate checks are not enough; this
check needs to be thorough.
(12) Describe how the document meets any required formal review
criteria, such as the MIB Doctor, media type, and URI type reviews.
Yes the document was reviewed by DNS RRtype Registry experts.
(13) Have all references within this document been identified as
either normative or informative?
(14) Are there normative references to documents that are not ready
for advancement or are otherwise in an unclear state? If such
normative references exist, what is the plan for their completion?
(15) Are there downward normative references references (see RFC
3967)? If so, list these downward references to support the Area
Director in the Last Call procedure.
(16) Will publication of this document change the status of any
existing RFCs? Are those RFCs listed on the title page header, listed
in the abstract, and discussed in the introduction? If the RFCs are
not listed in the Abstract and Introduction, explain why, and point to
the part of the document where the relationship of this document to
the other RFCs is discussed. If this information is not in the
document, explain why the WG considers it unnecessary.
(17) Describe the Document Shepherd's review of the IANA
considerations section, especially with regard to its consistency with
the body of the document. Confirm that all protocol extensions that
the document makes are associated with the appropriate reservations in
IANA registries. Confirm that any referenced IANA registries have been
clearly identified. Confirm that newly created IANA registries include
a detailed specification of the initial contents for the registry,
that allocations procedures for future registrations are defined, and
a reasonable name for the new registry has been suggested (see RFC
Only IANA action requested is to updat a reference upon publication of
(18) List any new IANA registries that require Expert Review for
future allocations. Provide any public guidance that the IESG would
find useful in selecting the IANA Experts for these new registries.
(19) Describe reviews and automated checks performed by the Document
Shepherd to validate sections of the document written in a formal
language, such as XML code, BNF rules, MIB definitions, etc.
