Abstract

    This document describes a procedure for performing the downgrading of
    old standards described in RFC 2026, as well as BCPs, without placing
    an unreasonable load on groups charged with performing other tasks in
    the IETF.

    It defines a new group, called the "Historical Standards Committee",
    which shall recommend to the IESG downgrading or progressing
    documents on the IETF standards track.  Ultimate decisions still rest

    of with the IESG, with appeal to the IAB.

1.  Introduction and history

    RFC 2026, and RFC 1602 before it, specified timelines for review of
    immature (draft or proposed) standards.  The purpose of such review
    was to determine whether such documents should be advanced, retired,
    or developed further.[1]

    This procedure has never been followed in the history of the IETF.
    Since this procedure has not been followed, members of the community
    have suggested that the retiring of a document to Historic is a
    significant event, which should be justified carefully - leading to
    the production of documents such as RFC 2556 (OSI connectionless
    transport services on top of UDP Applicability Statement for Historic
    Status) and RFC 3166 (Request to Move RFC 1433 to Historic Status).

    Such documents require significant time and effort on the part of
    authors, area directors, and the RFC Editor.  Indeed such effort
    should be reserved for advancing or maintaining immature standards.
    Hence, no document should be required for an immature standard to be
    retired.

2.  Bulk Decommissioning Procedure

    In order to decommission a standard, the level of the standard MUST
    be "proposed" or "draft" and the period of time for advancement as
    specified by RFC 2026 MUST have elapsed.  Furthermore, the Committee
    will consider no document that is being actively revised by an IETF
    working group.

    N.B.  elapse of time beyond the periods specified in RFC 2026 offers
    an opportunity and NOT a mandate for review.  The Committee should
    make a judgement as to the appropriateness of a review.

    The review procedure is as follows:
    o  For each standard to be reviewed, the Committee sends out a
       message to the IETF list and the lists deemed relevant, asking for
       implementation experience and active usage.
    o  If there are reports of implementation experience and/or active
       usage, the RFC is moved into the Committee's Individual
       Decommissioning Procedure.
    o  The Committee sends to the IESG the remaining list of documents it
       recommends be reclassified as either Historic or Outdated along
       with a record of steps taken to identify that standard"s use.
       That record should include pointers to archives, as well as a log
       of actions taken to seek out usage.

    o  The IESG will issue a Last Call for community input on all
       documents in question.
    o  The IESG will respond to the Committee's recommendation with a
       message to the IETF Announcement list, indicating which standards
       are marked Historic.
    o  Remaining standards are left unchanged, and are not to be further
       considered by the Committee for at least another twelve months.

3.  Individual Decommissioning Procedure

    This procedure is intended for use when one needs to consider more
    detailed evidence before deciding what to do with a document.

3.1  Procedure

    The Committee takes input from all sources it cares to take input
    from.  As it does so it will keep an archive and a record of all such
    input.  Once it determines a recommended action, it sends a
    recommendation to the IESG along with a pointer to the record, and
    the IESG will announce this to the IETF community if it agrees with
    the recommendation.

3.2  Evaluation criteria

    The decision on when to ask for reclassification is made by the
    Committee.

    Criteria that should be considered are:

    o  Usage.  A standard that is widely used should probably be left
       alone (better it should be advanced, but that is beyond the scope
       of this memo).
    o  Implementation.  A standard that is unimplemented is a clear
       candidate to be reclassified as Historic.
    o  Potential for harm.  A protocol that is unsafe where a clearly
       superior alternative is available should be considered for
       reclassification to Historic.
    o  Interest in further work.  If there is a reasonable expectation
       that the specification will be updated or advanced within a
       reasonable timeframe, the Committee should do nothing.

4.  Selection of the Committee

    NOTE IN DRAFT: This is intended to be simple, and convey the idea
    that signing up for this is an 1-year stint, not a permanent
    position.

    The IESG will send out a call for volunteers for the Cruft Committee

    once a year, and will choose from the volunteers, and appoint a
    chair.  A current member of the Committee may volunteer again if he/
    she wants to.

    The chair will report every six months via electronic mail to the
    IETF Announce mailing list on the Committee's progress.

    The Committee otherwise organizes its own work.

    The IESG may cut short the term of the Committee and send out a new
    call for volunteers if it finds that reasonable.
