Abstract

  This document describes methodologies that have been designed to
  improve and facilitate IETF document flow processing.  It specifies a
  set of procedures under which a working group chair or secretary
  serves as the primary Document Shepherd for a document that has been
  submitted to the IESG for publication.  Before this, the Area
  Director responsible for the working group has traditionally filled
  the shepherding role.

RFC 4858          Document Shepherding to Publication           May 2007


1.  Introduction

  Early in 2004, the IESG undertook several experiments aimed at
  evaluating whether any of the proposed changes to the IETF document
  flow process would yield qualitative improvements in document
  throughput and quality.  One such experiment, referred to as the
  "PROTO process" or "PROTO" (because it was created by the "PROcess
  and TOols" or PROTO [PROTO] team), is a set of methodologies designed
  to involve working group chairs or secretaries more directly in their
  documents' approval life cycle.  In particular, the PROTO team
  focused on improvements to the part of a document's life cycle that
  occurs after the working group and document editor have forwarded it
  to the IESG for publication.

  By the end of 2004, the IESG had evaluated the utility of the PROTO
  methodologies based on data obtained through several pilot projects
  that had run throughout the year, and subsequently decided to adopt
  the PROTO process for all documents and working groups.  This
  document describes this process.

  The methodologies developed and piloted by the PROTO team focus on
  the working group chair or secretary as the primary Document
  Shepherd.  The primary objective of this document shepherding process
  is to improve document-processing throughput and document quality by
  enabling a partnership between the Responsible Area Director and the
  Document Shepherd.  In particular, this partnership has the explicit
  goal of enfranchising the Document Shepherd while at the same time
  offloading a specific part of the follow-up work that has
  traditionally been responsibility of the Responsible Area Director.
  The Responsible Area Director has tens or many tens of documents to
  follow, while the Document Shepherd has only a few at a time.
  Flowing the responsibility to the working group level can ensure more
  attention and more timely response.

  Consequently, the document shepherding process includes follow-up
  work during all document-processing stages after Working Group Last
  Call, i.e., during AD Evaluation of a document, during IESG
  Evaluation, and during post-approval processing by IANA and the RFC
  Editor.  In these stages, it is the responsibility of the Document
  Shepherd to track and follow up on feedback received on a document
  from all relevant parties.

  The Document Shepherd is usually a chair of the working group that
  has produced the document.  In consultation with the Responsible Area
  Director, the chairs may instead decide to appoint the working group
  secretary as the responsible Document Shepherd.

2.  Terminology

  The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
  "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
  document are to be interpreted as described in BCP 14, RFC 2119
  [RFC2119].

3.  Process Description

  The document shepherding process consists of the following tasks:

  o  Providing the Document Shepherd Write-Up accompanying a document
     that is forwarded to the IESG when publication is requested, as
     described in Section 3.1.

  o  During AD Evaluation of the document by the Responsible Area
     Director, managing the discussion between the editors, the working
     group, and the Responsible Area Director, as described in
     Section 3.2.

  o  During an IETF Last Call, if performed for the shepherded
     document, following up on community feedback and review comments.

  o  During IESG Evaluation, following up on all IESG feedback
     ("DISCUSS" and "COMMENT" items) related to the shepherded
     document, as described in Section 3.3.

  o  Following up on IANA and RFC Editor requests as described in
     Section 4 and Section 5.

  The shepherd must keep the document moving forward, communicating
  about it with parties who review and comment on it.  The shepherd
  must obtain the working group's consensus for any substantive
  proposed changes.  The shepherd is the leader for the document and
  for the working group, and maintains a critical and technical
  perspective.  In summary, the Document Shepherd continues to care for
  a shepherded document during its post-WG lifetime just as he or she
  has done while responsible for the document in the working group.

  Before any document shepherding takes place, a single Document
  Shepherd MUST be identified for a document (he or she will be named
  in the Document Shepherd Write-Up).  Frequently, the chairs and the
  Responsible Area Director will decide that the working group will
  adopt the PROTO process for all their future documents.  After that
  decision, the chairs, in consultation with the Responsible Area
  Director, decide on who should act as Document Shepherd for any given
  document.  This is typically and by default one of the chairs of the
  working group.  In consultation with the Responsible Area Director,



Levkowetz, et al.            Informational                      [Page 4]

RFC 4858          Document Shepherding to Publication           May 2007


  the chairs MAY also decide to appoint the working group secretary as
  Document Shepherd for a given document.  The Document Shepherd SHOULD
  NOT be an editor of the shepherded document.

  It is intended that the Document Shepherd role be filled by one
  person during the entire shepherding process.  However, situations
  may occur when the Document Shepherd role may be reassigned to
  different persons during the lifetime of a document.  It is up to the
  chairs and Responsible Area Director to identify situations when this
  may become necessary, and then consult to appoint a new Document
  Shepherd.

  It is important to note that the document shepherding process only
  applies to documents that are the product of a working group.  It
  does not apply to documents that originate elsewhere.  Additionally,
  Section 6 discusses other instances in which the document shepherding
  process does not apply.

3.1.  Document Shepherd Write-Up

  When a working group decides that a document is ready for submission
  to the IESG for publication, it is the task of the Document Shepherd
  to complete a "Document Shepherd Write-Up" for the document.

  There are two parts to this task.  First, the Document Shepherd
  answers questions (1.a) to (1.j) below to give the Responsible Area
  Director insight into the working group process that applied to this
  document.  Note that while these questions may appear redundant in
  some cases, they are written to elicit information that the
  Responsible Area Director must be aware of (to this end, pointers to
  relevant entries in the WG archive are helpful).  The goal here is to
  inform the Responsible Area Director about any issues that may have
  come up in IETF meetings, on the mailing list, or in private
  communication that they should be aware of prior to IESG Evaluation
  of the shepherded document.  Any significant issues mentioned in the
  questionnaire will probably lead to a follow-up discussion with the
  Responsible Area Director.

  The second part of the task is to prepare the "Document Announcement
  Write-Up" that is input both to the ballot for the IESG telechat and
  to the eventual IETF-wide announcement message.  Item number (1.k)
  describes the elements of the Document Announcement Write-Up.

  Some examples of Document Announcement Write-Ups are included in
  Appendix A, and there are many more examples with subject lines such
  as "Protocol Action" and "Document Action" in the IETF-announce
  mailing list archive.




Levkowetz, et al.            Informational                      [Page 5]

RFC 4858          Document Shepherding to Publication           May 2007


  The initial template for the Document Shepherd Write-Up is included
  below, but changes are expected over time.  The latest version of
  this template is available from the IESG section of the IETF web
  site.

  (1.a)  Who is the Document Shepherd for this document?  Has the
         Document Shepherd personally reviewed this version of the
         document and, in particular, does he or she believe this
         version is ready for forwarding to the IESG for publication?

  (1.b)  Has the document had adequate review both from key WG members
         and from key non-WG members?  Does the Document Shepherd have
         any concerns about the depth or breadth of the reviews that
         have been performed?

  (1.c)  Does the Document Shepherd have concerns that the document
         needs more review from a particular or broader perspective,
         e.g., security, operational complexity, someone familiar with
         AAA, internationalization, or XML?

  (1.d)  Does the Document Shepherd have any specific concerns or
         issues 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.  Has an IPR disclosure related to this document
         been filed?  If so, please include a reference to the
         disclosure and summarize the WG discussion and conclusion on
         this issue.

  (1.e)  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?

  (1.f)  Has anyone threatened an appeal or otherwise indicated extreme
         discontent?  If so, please summarize the areas of conflict in
         separate email messages to the Responsible Area Director.  (It
         should be in a separate email because this questionnaire is
         entered into the ID Tracker.)

  (1.g)  Has the Document Shepherd personally verified that the
         document satisfies all ID nits?  (See
         http://www.ietf.org/ID-Checklist.html and
         http://tools.ietf.org/tools/idnits/.)  Boilerplate checks are
         not enough; this check needs to be thorough.  Has the document



Levkowetz, et al.            Informational                      [Page 6]

RFC 4858          Document Shepherding to Publication           May 2007


         met all formal review criteria it needs to, such as the MIB
         Doctor, media type, and URI type reviews?  If the document
         does not already indicate its intended status at the top of
         the first page, please indicate the intended status here.

  (1.h)  Has the document split its references into normative and
         informative?  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
         strategy for their completion?  Are there normative references
         that are downward references, as described in [RFC3967]?  If
         so, list these downward references to support the Area
         Director in the Last Call procedure for them [RFC3967].

  (1.i)  Has the Document Shepherd verified that the document's IANA
         Considerations section exists and is consistent with the body
         of the document?  If the document specifies protocol
         extensions, are reservations requested in appropriate IANA
         registries?  Are the IANA registries clearly identified?  If
         the document creates a new registry, does it define the
         proposed initial contents of the registry and an allocation
         procedure for future registrations?  Does it suggest a
         reasonable name for the new registry?  See [RFC2434].  If the
         document describes an Expert Review process, has the Document
         Shepherd conferred with the Responsible Area Director so that
         the IESG can appoint the needed Expert during IESG Evaluation?

  (1.j)  Has the Document Shepherd verified that sections of the
         document that are written in a formal language, such as XML
         code, BNF rules, MIB definitions, etc., validate correctly in
         an automated checker?

  (1.k)  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:

         Technical Summary
            Relevant content can frequently be found in the abstract
            and/or introduction of the document.  If not, this may be
            an indication that there are deficiencies in the abstract
            or introduction.








Levkowetz, et al.            Informational                      [Page 7]

RFC 4858          Document Shepherding to Publication           May 2007


         Working Group Summary
            Was there anything in the WG process that is worth noting?
            For example, was there controversy about particular points
            or were there decisions where the consensus was
            particularly rough?

         Document Quality
            Are there existing implementations of the protocol?  Have a
            significant number of vendors indicated their plan to
            implement the specification?  Are there any reviewers that
            merit special mention as having done a thorough review,
            e.g., one that resulted in important changes or a
            conclusion that the document had no substantive issues?  If
            there was a MIB Doctor, Media Type, or other Expert Review,
            what was its course (briefly)?  In the case of a Media Type
            Review, on what date was the request posted?

         Personnel
            Who is the Document Shepherd for this document?  Who is the
            Responsible Area Director?  If the document requires IANA
            experts(s), insert 'The IANA Expert(s) for the registries
            in this document are <TO BE ADDED BY THE AD>.'

  The Document Shepherd MUST send the Document Shepherd Write-Up to the
  Responsible Area Director and [email protected] together with
  the request to publish the document.  The Document Shepherd SHOULD
  also send the entire Document Shepherd Write-Up to the working group
  mailing list.  If the Document Shepherd feels that information which
  may prove to be sensitive, may lead to possible appeals, or is
  personal needs to be written up, it SHOULD be sent in direct email to
  the Responsible Area Director, because the Document Shepherd Write-Up
  is published openly in the ID Tracker.  Question (1.f) of the
  Write-Up covers any material of this nature and specifies this more
  confidential handling.

  The Document Shepherd Write-Up is entered into the ID Tracker
  [IDTRACKER] as a "Comment".  The name and email address of the
  Document Shepherd are entered into the ID Tracker, currently as a
  "Brief Note" (this may change in the future).  The email address of
  the Document Shepherd MUST also be added to the "State or Version
  Change Notice To" field (typically the email addresses of all working
  group chairs, authors, and the secretary will be added).

  Entering the name and email of the Document Shepherd into the ID
  Tracker is REQUIRED to ensure that he or she will be copied on the
  email exchange between the editors, chairs, the IESG, the IESG
  secretariat, IANA, and the RFC Editor during the review and approval
  process.  There are still manual steps required for these parties to



Levkowetz, et al.            Informational                      [Page 8]

RFC 4858          Document Shepherding to Publication           May 2007


  ensure that they include the Document Shepherd, but it is hoped that
  in the future, automated tools will ensure that Document Shepherds
  (and others) receive necessary communications.

  The contact information for the Document Shepherd is also important
  for the Gen-ART team [GEN-ART], area directorates, and other review
  teams, so they can know to whom to address reviews, in addition to
  the Responsible Area Director.

3.2.  Document Shepherding during AD Evaluation

  The steps for document shepherding during AD Evaluation are as
  follows:

  (2.a)  The Responsible Area Director reads, evaluates, and comments
         on the document, as is the case when not using the document
         shepherding process.  If the Responsible Area Director
         determines that the document is ready for IESG Evaluation, he
         or she indicates this to the Document Shepherd and the
         document shepherding process continues as described in
         Section 3.3.

  (2.b)  If the Responsible Area Director has identified issues with a
         document that must be addressed before IESG Evaluation can
         commence, he or she sends a full evaluation to the Document
         Shepherd and SHOULD also enter the review into the ID Tracker.

  (2.c)  The Document Shepherd reads the AD Evaluation comments, making
         very certain that all comments are understood, so that it is
         possible to follow up on them with the editors and working
         group.  If there is some uncertainty as to what is requested,
         this SHOULD be resolved with the Responsible Area Director.

  (2.d)  The Document Shepherd sends the AD Evaluation comments to the
         editors and to the working group mailing list, in order to
         have a permanent record of the comments.  It is RECOMMENDED
         that the Document Shepherd solicit from the editors an
         estimate on when the required changes will be completed and a
         revised document can be expected.  Working groups that use
         issue tracking SHOULD also record the issues (and eventually
         their resolution) in their issue tracker.

  (2.e)  During the production of a revised document that addresses the
         AD Evaluation comments, it is RECOMMENDED that the editors
         keep a list showing how each comment was addressed and what
         the revised text is.  It is RECOMMENDED that this list be
         forwarded to the Responsible Area Director together with the
         revised document.



Levkowetz, et al.            Informational                      [Page 9]

RFC 4858          Document Shepherding to Publication           May 2007


  (2.f)  In the event that the editors or working group disagrees with
         a comment raised by the Responsible Area Director or has
         previously considered and dismissed the issue, the Document
         Shepherd MUST resolve the issue with the Responsible Area
         Director before a revised document can be submitted.

  (2.g)  The Document Shepherd iterates with the editors (and working
         group, if required) until all outstanding issues have been
         resolved and a revised document is available.  At this point,
         the Document Shepherd notifies the Responsible Area Director
         and provides him or her with the revised document, the summary
         of issues, and the resulting text changes.

  (2.h)  The Responsible Area Director verifies that the issues he or
         she found during AD Evaluation are resolved in the revised
         version of the document by starting the process described in
         this section at step (2.a).

  (2.i)  If the document underwent an IETF Last Call and the AD
         concludes that significant issues were raised during the Last
         Call, then steps (2.b) through (2.h) need to be applied
         addressing the Last Call issues.  This requires the
         Responsible Area Director to present to the Document Shepherd
         those Last Call issues raised only to the IESG.

3.3.  Document Shepherding during IESG Evaluation

  During IESG Evaluation of a document, ADs can bring forward two kinds
  of remarks about a document: DISCUSS items and COMMENT items.  A
  DISCUSS blocks a document's approval process until it has been
  resolved; a COMMENT does not.  This section details the steps that a
  Document Shepherd takes to resolve any DISCUSS and COMMENT items
  brought forward against a shepherded document during IESG Evaluation.

  Note that DISCUSS and COMMENT items are occasionally written in a
  manner that makes their intent unclear.  In these cases, the Document
  Shepherd SHOULD start a discussion with the ADs who brought the items
  up to clarify their intent, keeping the Responsible Area Director
  informed.  If this fails to clarify the intent, the Responsible Area
  Director may need to work towards a clarification inside the IESG.

  (3.a)  Leading up to the IESG conference call, the Document Shepherd
         may see emails about the document from directorate reviewers
         on behalf of one or more ADs and also emailed copies of
         DISCUSS and COMMENT items entered into the ID Tracker.  The
         Document Shepherd SHOULD immediately begin to work on
         resolving DISCUSS and COMMENT items with the ADs who have
         raised them, keeping the Responsible Area Director copied on



Levkowetz, et al.            Informational                     [Page 10]

RFC 4858          Document Shepherding to Publication           May 2007


         the email exchange, so that he or she is able to support the
         activity during the conference call.  When dealing with
         directorate reviews, the Document Shepherd MUST involve the
         ADs to whom these directorates report to ensure that these ADs
         consider the review comments that need resolving.

  (3.b)  Immediately following the conference call, when the document
         changes state from the "IESG Evaluation" state to one of the
         states requiring Document Shepherd action, e.g., "IESG
         Evaluation: Revised ID Needed" or "IESG Evaluation: AD
         Followup", the Document Shepherd will receive email.  A state
         of "AD Followup" typically signifies the Responsible Area
         Director's hope that a resolution may be possible through a
         continued discussion or (more usually) through a small set of
         changes as "Notes to the RFC Editor".

         Note that there may be very exceptional cases when DISCUSS
         items are registered after an IESG conference call.  In these
         cases, the AD who has raised the DISCUSS MUST notify the
         Document Shepherd about it.  (The notification facility in the
         ID Tracker is very convenient for this purpose and also for
         the cases where the DISCUSS and COMMENT items are updated
         after they are partially resolved.)

  (3.c)  The Document Shepherd then queries the ID Tracker to collect
         the remaining DISCUSS and COMMENT items raised against the
         document.  The Document Shepherd analyzes these items and
         initializes contact with the ADs who have placed them.  The
         Responsible Area Director MUST be copied on all correspondence
         related to active DISCUSS or COMMENT items.  This does not
         place the Responsible Area Director in the critical path
         towards a resolution, but should keep him or her informed
         about the state of the discussion.

         +-------+              +-------+               +-------+
         | (3.b) | -----------> | (3.c) | ------------> | (3.d) |
         +-------+  Comments    +-------+   Comments    +-------+

                                  |   |  discussion required)
                                  +---+

  (3.d)  The Document Shepherd then coordinates the resolution of
         DISCUSS and COMMENT items and builds a consistent
         interpretation of the comments.  This step is similar to much
         of the process described in Section 3.2.

             +--------------------------+

  (3.e)  The Document Shepherd then communicates the DISCUSS and
         COMMENT items to the document editors and the working group,
         alerting them of any changes to the document that have
         accumulated during IESG processing, such as "Notes to the RFC
         Editor".  If any changes will be substantive, the Document
         Shepherd, in consultation with the Responsible Area Director,
         as during other stages, MUST confirm working group consensus
         or sometimes even IETF consensus.

  (3.f)  After the editors resolve the DISCUSS and COMMENT items, the
         Document Shepherd reviews the resulting new version of the
         document, which will be a revised document, a set of "Notes to
         the RFC Editor", or both, using his or her technical expertise
         to ensure that all raised DISCUSS and COMMENT issues have been
         resolved.

         Note that the Document Shepherd MAY also suggest resolutions
         to DISCUSS and COMMENT items, enter them into an issue
         tracker, or perform other steps to streamline the resolution
         of the evaluation comments.  It is very important to resolve
         the comments in a timely way, while the discussion is current
         for everyone involved.

  (3.g)  When the Document Shepherd is satisfied that the revised
         document addresses the evaluation comments, he or she
         communicates the resolution to the Responsible Area Director
         and the ADs that had raised the DISCUSS and COMMENT items.

  (3.h)  Each AD who had raised a DISCUSS checks whether the
         communicated resolution addresses his or her items.  If it
         does, the AD will clear the DISCUSS.  If it does not, the AD
         notifies the Document Shepherd and adds information to the ID
         Tracker explaining why the DISCUSS was not resolved.  The
         Document Shepherd informs the working group accordingly.
         (COMMENT items need not be checked and cleared, because they
         do not block the document, but ADs are encouraged to do so.)

         If a DISCUSS was not resolved to the satisfaction of the AD
         that has raised it or the Responsible Area Director, two
         possibilities exist:



Levkowetz, et al.            Informational                     [Page 12]

RFC 4858          Document Shepherding to Publication           May 2007


         (a)  The process returns to step (3.d), or

         (b)  If no progress can be made on the resolution of the
              DISCUSS with the AD who has raised it, despite repeated
              clarifications and discussions, the Responsible Area
              Director should take over continued shepherding of the
              document.  Such a situation may be indicative of larger
              issues that the PROTO process was not designed to handle.

         Once the process above has cleared all DISCUSS items, document
         shepherding continues with step (3.i).

  (3.i)  The Responsible Area Director moves the document to the
         "Approved - Announcement to be sent" state in the ID Tracker.
         If he or she deems the changes to the revised document
         significant, there may be a new WG Last Call, or possibly a
         new IETF Last Call.  The document goes through a new full IESG
         Evaluation process if there is a new IETF Last Call.

4.  Shepherding the Document's IANA Actions

  IETF working group documents often include considerations requiring
  actions by the IANA, such as creating a new registry or adding
  information to an existing registry, perhaps after consulting an
  IESG-appointed Expert.  Sometimes the Document Shepherd must keep
  track of certain IANA actions to be completed by the IESG, such as
  ratifying the appointment of a designated Expert called for in the
  IANA Considerations.  IANA-related processing may also include a
  specified type of Expert review, such as review of proposed MIME
  media types on the designated ietf-types mailing list.

  The IANA reviews IETF documents and requests responses at any or all
  of the following times: in response to IETF Last Call, during the
  IESG Evaluation review of the document, and at the time when the IANA
  performs actions in its web-based registry for the document, usually
  but not always after IESG approval of the document.  More details of
  the IANA process and IETF interaction are found in [RFC2434].

  At the time of this publication, RFC 2434 is under revision
  [RFC2434bis], and the updates are and will be of value to the
  Document Shepherd.  Note that the Document Shepherd MUST determine
  (by individual review and consultation with others) what is the most
  recent and the most applicable IANA information and guidance for his
  or her document, be it the overall guidance, or external documents in
  his or her area, or in other areas.  An example of an external
  document is [RFC4020].





Levkowetz, et al.            Informational                     [Page 13]

RFC 4858          Document Shepherding to Publication           May 2007


  Whenever an IANA request comes, during whatever phase of the
  shepherding process, the requester from IANA MUST ensure that the
  Document Shepherd and the Responsible Area Director both receive the
  request.  The Document Shepherd is responsible for responding as
  rapidly as possible.  He or she should discuss requests that
  introduce any possible concerns with the working group.  The Document
  Shepherd and the Responsible Area Director may decide in consultation
  that an IANA request leads to a change that needs additional review
  or approval.

  In general, the Document Shepherd ensures that the IANA process
  completes, checks that the registry is correct and that the IANA
  Matrix (http://www.iana.org/numbers.html) is complete and consistent,
  and troubleshoots when all is not well.  At the end of IANA
  processing, the Document Shepherd should be sure that the RFC Editor
  has acknowledged IANA conclusion, i.e., that the handoff has been
  made.

  In summary, the task of shepherding the IANA actions is often
  overlooked, but is as important to coordinate and manage as all the
  other document reviews the Document Shepherd has managed.  As with
  those, the Document Shepherd contributes greatly to quality and
  timeliness of the document by effective and responsive shepherding of
  the IANA requests.

5.  Document Shepherding after IESG Approval

  After the IESG Evaluation and resolution described in Section 3.3,
  the IESG approves the document, and the Responsible Area Director
  uses the ID Tracker to ask for any final changes to the Document
  Announcement Write-Up and for it to be issued.  The Document Shepherd
  may have some edits for the Responsible Area Director, such as minor
  "Notes to the RFC Editor", and this is the time to consult and
  provide them.

  The IESG approval announcement goes to the general community and to
  the RFC Editor, and now the Document Shepherd (identified in the
  Announcement Write-Up) continues to shepherd the document through its
  technical publication.  The RFC Editor currently makes a number of
  types of requests to the authors, Document Shepherd and Responsible
  Area Director.  The Document Shepherd SHOULD lead in responding to
  the RFC Editor and shepherd the document during the post-approval
  period to its publication.

  The RFC Editor request types include: editorial queries about
  dangling or missing informative and normative citations (good
  shepherding should try to catch these earlier, but they happen);
  requests for the document source (e.g., XML or nroff); occasional



Levkowetz, et al.            Informational                     [Page 14]

RFC 4858          Document Shepherding to Publication           May 2007


  technical comments; and copy-edits for review and close scrutiny by
  the authors (AUTH48).  For the latter, the Document Shepherd SHOULD
  lead in checking that copy-edits have in no case affected a consensus
  wording of the working group that prepared the document, and SHOULD
  bring speed to this checking by multiple coauthors.  The Document
  Shepherd also consults with the Responsible Area Director on
  reviewing proposed post-approval changes to the document by any
  author.  These may require Area Director approval, and they often
  need to be presented to the working group for consent if not a full
  consensus procedure.

  As in other phases of document shepherding, the Document Shepherd
  provides attentiveness and timeliness by serving as the informed
  representative of the document and helping its advancement and its
  integrity.

6.  When Not to Use the Document Shepherding Process

  As mentioned in Section 3, the Document Shepherd SHOULD NOT be an
  editor of the shepherded document.  If this cannot be avoided by
  making another working group chair or secretary the Document
  Shepherd, the document shepherding process SHOULD NOT be used.  There
  are several other cases in which the document shepherding process
  SHOULD NOT be used.  These include:

  1.  Cases where the Document Shepherd is the primary author or editor
      of a large percentage of the documents produced by the working
      group.

  2.  Cases where the Responsible Area Director expects communication
      difficulties with the Document Shepherd (either due to
      experience, strong views stated by the Document Shepherd, or
      other issues).

  3.  Cases where the working group itself is either very old, losing
      energy, or winding down (i.e., cases where it would not be
      productive to initiate new processes or procedures).

  Finally, note that other cases exist in which using the document
  shepherding process may not be productive.  The final determination
  as to whether or not to use the document shepherding process is left
  to the Responsible Area Director.  If the document shepherding
  process is not used, the Responsible Area Director acts as Document
  Shepherd, per the existing procedures of shepherding by Area
  Directors.

Appendix A.  Example Document Announcement Write-Ups

  This appendix includes two examples of Document Announcement Write-
  Ups.  Many more examples with Subject lines such as "Protocol Action"
  and "Document Action" can be found in the IETF-announce mailing list
  archive.

A.1.  Example Document Announcement Write-Up for
     draft-ietf-avt-rtp-midi-format

  Technical Summary

     These documents define the RTP Payload format for MIDI (Musical
     Instrument Digital Interface), and additional guidelines on
     implementation specifically concerning the timing of reception and
     transmission for best performance in different applications.  MIDI
     is a real-time media, which however is brittle to losses and
     errors.  Therefore the RTP payload format defines recovery
     journals as a way of avoiding persistent audible errors, and
     discusses congestion control handling for these journals.

     The RTP payload for MIDI encodes the broad range of MIDI commands.
     The format is suitable for interactive applications (such as
     network musical performance) and content-delivery (such as file
     streaming).

  Working Group Summary

     There is consensus in the WG to publish these documents.

  Document Quality

     This RTP Payload format has been implemented during the
     development of the specification and successfully tested over an
     IP network between two remote sites, thus showing that the
     technical solution is successfully working.  It has been reviewed
     by the MIDI Manufacturers Association and their comments have been
     addressed.

  Personnel

     Magnus Westerlund and Colin Perkins jointly shepherded this
     document.  Allison Mankin reviewed the document for the IESG,
     including a careful review with the editor of the media types, in
     parallel with ietf-types list review requested on 2006-01-08,
     which raised no issues.

A.2.  Example Document Announcement Write-Up for
     draft-ietf-imss-ip-over-fibre-channel

  Technical Summary

     This document specifies the encapsulation of IPv6, IPv4 and ARP
     packets over Fibre Channel.  This document also specifies the
     methods for forming IPv6 link-local addresses and statelessly
     autoconfigured IPv6 addresses on Fibre Channel networks, and a
     mechanism to perform IPv4 address resolution over Fibre Channel
     networks.  This document (when published as RFC) obsoletes RFC2625
     and RFC3831.

  Working Group Summary

     This document has been reviewed by Fibre Channel experts in
     Technical Committee T11 (Fibre Channel standards organization) in
     addition to members of the IMSS WG.  There is solid support for
     this document both in the WG and from T11.

  Document Quality

     This document replaces and consolidates two separate RFCs on IPv4
     over Fibre Channel (RFC 2625) and IPv6 over Fibre Channel (RFC
     3831).  Most of its technical content is unchanged from those
     RFCs.  The technical changes that have been made are primarily
     based on implementation experience.

  Personnel

     The protocol has been reviewed for the IESG by David L. Black (WG
     chair).  Bert Wijnen has reviewed this document for the IESG.  In
     addition, Brian Haberman has done a review for the INT Area as
     requested by WG-chair (David Black) via Margaret Wasserman.
