IESG Statement on Designating RFCs as Historic
Date: 27 June 2011
RFC 2026 states the following:
A specification that has been superseded by a more recent specification
or is for any other reason considered to be obsolete is assigned to the "Historic" level.
In practice, the Historic status is not automatically assigned to RFCs
that have been "obsoleted". That is, when an RFC that contains the "Obsoletes: RFC XXXX" header is published the RFC editor does not
automatically apply the Historic status to the XXXX RFC. Note that in
some situations this is perfectly acceptable because multiple versions
of an Internet Standard are permitted to "honor the installed base," as
per RFC 2026.
If authors wish to change the status of RFCs that are in the obsoletes
header to Historic, then the authors must include an explicit statement
for the RFC editor to do so; preferably in the abstract and
introduction. Further, when an AD sponsors a draft that includes the
obsoletes header, then the AD should ask the authors whether the authors
intended to move the RFC(s) listed in the obsoletes header to Historic
status.
If an author wishes to publish a document directly to Historic status
the preferred approach is to publish an I-D with the "Intended Status:
Historic" in the header.
As allowed by RFC 2026 Section 6.4, anyone may request that the IESG
move an RFC to Historic that is simply and obviously obsolete (and in
A/S terms "not recommended") without the need to produce an
internet-draft. The IESG can issue Last Calls to request that the RFC in
question be moved to Historic.
If a document (whatever its intended status) moves another document to "Historic" status, the Last-Call should go out saying, "Last
Call:<draft-blah-blah-blah> to Informational and RFC XXXX to Historic",
the document should be handled as a Protocol Action on the IESG agenda
using IESG Protocol Action procedures, and a "Protocol Action"
announcement should be sent out when the document is approved.
Moving a document to Historic status means that the document is "not
[an] Internet Standards in any sense," as per RFC 2026.
