1. Introduction
[[ Note to be removed by the RFC Editor: This version of the draft
describes a completely modified procedure compared to the one
presented at IETF74, which did not obtain consensus. It contains
small and large changes throughout. Discussion is invited on the
ipr-wg@ietf.org list. ]]
Terminology: In this document, the phrases "prior to RFC 5378" and
"pre-5378" refer to IETF Contributions made before November 10, 2008,
when RFC 5378 became effective. The phrase "Original Contributor"
refers to an Indirect Contributor in the sense of [RFC5378], whose
Contribution was prior to RFC 5378. Other terminology is defined in
RFC 5378.
RFC 5378 failed to describe one case that has practical consequences.
The case is this: a new IETF Contribution contains material derived
from one or more pre-5378 Contributions, but the Original
Contributors have not agreed to the specific additional rights
granted to the IETF under RFC 5378 compared to previous IETF rules.
In this case, the Contributor cannot accurately make the warranties
required by RFC 5378 with respect to the pre-5378 material included
in his or her Contribution.
This can arise when the Original Contributors, or their assigns, are
unwilling, unresponsive, unfindable, deceased, no longer in business,
or simply too numerous.
This document is intended to specify the simplest possible solution
for such cases. Additional background information is given in
Appendix B below.
2. Mandatory Procedure
It should be noted that Section 5.6 of [RFC5378] already requires
that Indirect Contributors must be acknowledged in all IETF
documents. This continues a requirement previously specified in
section 3.4 (a) of [RFC3978] and [RFC3667], and in section 10.3.1 (4)
of [RFC2026]. The present document extends this requirement in
certain cases.
Contributors of Internet-Drafts that contain text originally
contributed to the IETF by other persons prior to RFC 5378 have
certain responsibilities, to be exercised to the best of their
knowledge and ability.
Carpenter & Alvestrand Expires November 12, 2009 [Page 3]
Internet-Draft Including old text May 2009
Unless the Contributor(s) know that the Original Contributors have
agreed to their text being contributed under the terms of RFC 5378,
the Internet-Draft and any resulting RFC must include an appropriate
legend of disclaimer. The current text of this legend will be
specified by the IETF Trust's "Legend Instructions" as defined in
[RFC5378]. The initial version of this text is given for
informational purposes in Appendix A below.
If and only if this legend is included:
o The acknowledgement required by Section 5.6 of [RFC5378] should
identify the source(s) of pre-5378 text, such as RFCs and
Internet-Drafts. This requirement does not extend to small
fragments of text culled from IETF discussions.
o The acknowledgement should also identify which Original
Contributors contributed which sections of pre-5378 text. This
requirement does not apply if the text concerned is scattered
throughout the document.
The IETF Trust is directed to ensure that its policies and licenses
allow for documents including the disclaimer.
3. Voluntary Procedures
[[ Discussion invited: is it appropriate and useful to include these
voluntary procedures? The BOF at IETF74 seemed to accept a "MAY"
approach, but there was no clear consensus call on that point. ]]
All Contributors to the IETF prior to RFC 5378 are invited to provide
retroactively to the IETF Trust the rights in their Contributions
required by RFC 5378.
The IETF Trust may provide a public register of pre-5378 documents
for which the rights required by RFC 5378 have been provided
retroactively, and a public register of rights holders who have
retroactively provided such rights for all their pre-5378
Contributions.
Contributors of Internet-Drafts including pre-5378 material who wish
to avoid also including the disclaimer may take any steps they wish,
or ask helpers to take such steps, to contact the Original
Contributors and obtain their agreement to their text being
contributed under the terms of RFC 5378.
4. Security Considerations
This document does not affect the security of the Internet.

5. IANA Considerations
This document requires no action by the IANA.
6. Acknowledgements
Much mailing list discussion by the IETF community, and private email
discussions with Scott Bradner, Jorge Contreras, Russ Housley, John
Klensin, and others, have led to this document. The discussions at
IETF74 in San Francisco led a significant rewrite.
This document was produced using the xml2rfc tool [RFC2629].

Appendix A. Non-normative initial version of disclaimer
The current valid version should be taken from the IETF Trust's
"Legal Provisions Relating to IETF Documents", originally located at
<http://trustee.ietf.org/policyandprocedures.html>. The initial
version was:
[[ Note to RFC Editor: please make sure this is the Trust's current
disclaimer text at the time of publication. ]]
"This document may contain material from IETF Documents or IETF

Internet-Draft Including old text May 2009
Contributions published or made publicly available before November
10, 2008. The person(s) controlling the copyright in some of this
material may not have granted the IETF Trust the right to allow
modifications of such material outside the IETF Standards Process.
Without obtaining an adequate license from the person(s) controlling
the copyright in such materials, this document may not be modified
outside the IETF Standards Process, and derivative works of it may
not be created outside the IETF Standards Process, except to format
it for publication as an RFC or to translate it into languages other
than English."
Appendix B. Non-normative explanation of background
This Appendix is not part of the formal rules of the IETF and does
not purport to offer legal advice. Contributors to the IETF who are
in any doubt as to how to proceed are advised to take appropriate
legal advice.
Copyright provisions for IETF documents were first defined in
[RFC2026] and were subsequently refined in [RFC3667] and [RFC3978].
Their effect has always been to allow free use of contributions to
the IETF process in IETF discussions, IETF drafts and IETF
publications. Even prior to RFC 2026, such free use was considered
the norm by all participants. RFC 5378 makes no difference to the
IETF's right to use contributions freely within the IETF process.
However, use of contributions outside the IETF process has always
been subject to some limitations. The IETF does not require
copyright transfers, and as a result contributors retain control
except to the extent that the IETF rules applicable at the time of
submission indicate otherwise.
IETF and RFC Editor rules and practices have always allowed RFCs to
be reproduced as complete documents, in English or in translation.
This has not changed.
The particular point at issue is the use of IETF contributions in
works derived from IETF documents by third parties outside the IETF
process. The rules in RFC 2026, RFC 3667 and RFC 3978 do not allow
this without the contributors' permission, except for limited
exceptions.
The exception defined in RFC 2026 is that "derivative works that
comment on or otherwise explain it [the IETF document] or assist in
its implmentation [sic] may be prepared, copied, published and
distributed, in whole or in part, without restriction of any kind..."
This has been generally interpreted to allow extracts to be used in
software implementations, user manuals, text books, and the like.
Carpenter & Alvestrand Expires November 12, 2009 [Page 6]
Internet-Draft Including old text May 2009
RFC 3667 and RFC 3978 added explicit wording to further clarify that
code extracts may be freely used by anybody: "(E) to extract, copy,
publish, display, distribute, modify and incorporate into other
works, for any purpose (and not limited to use within the IETF
Standards Process) any executable code or code fragments that are
included in any IETF Document...". However, RFC 3667 and RFC 3978 do
not mention the category of "derivative works that comment on or
otherwise explain..." For contributions made when they were in
force, use of non-code extracts for commentary and explanation
outside the IETF process appears formally to require explicit
permission from the original contributors. In many jurisdictions,
this might fall under the "fair use" provisions of copyright law or
their local equivalent, and in any case most RFC authors would be
glad of such use.
[RFC5378] extends the rights granted by contributors to the IETF (in
practice, the IETF Trust) such that the IETF itself (via the Trust)
can grant the right to make derivative works to third parties. Short
of a full copyright transfer to the IETF, this cleans up the
situation for new documents. It allows the IETF to grant rights to
third parties to make use of new IETF documents in any way the IETF
is happy with, and it leaves the original contributors free to do
what they want with their own work (even in ways the IETF is unhappy
with).
As noted in the Introduction, there is an issue if a current IETF
contribution, submitted under the new rules of RFC 5378, includes
material originally submitted by a different contributor under one of
the previous rules (including prior to RFC 2026 when there was no
rule). Suppose Alice plans to submit a draft under RFC 5378
containing a modified version of a section of an RFC originally
submitted by Bob under one of the older rules. This is a very common
situation, for example when a protocol needs clarification or
correction, or a new version is most conveniently documented by
revising the old text. There are several possible approaches, all of
which appear to fully respect Bob's rights without significantly
delaying publication:
1. Alice realises that the old material was written by a large
number of "Bobs", or by people no longer active in the IETF and
possibly even deceased, or by people who no longer work for the
employer to whom their copyright was assigned by their conditions
of employment, or any other situation where obtaining their
agreement is a substantial effort or a practical impossibility.
In this case, Alice includes acknowledgments and the disclaimer,
and we are done. The acknowledgment will look something like
"Significant amounts of text in sections X, Y and Z have been
adapted from RFCxxxx written by Bob."
Carpenter & Alvestrand Expires November 12, 2009 [Page 7]
Internet-Draft Including old text May 2009
2. Alice looks at the IETF Trust web site, and finds that the
previous RFC is listed as already being OK for use under RFC 5378
conditions, or that Bob and his employer are listed as allowing
any of their contributions to be so used. Alice submits a draft
using the normal RFC 5378 boilerplate, and includes an
acknowledgement of Bob's contribution, such as: "Significant
amounts of text have been adapted from RFCxxxx written by Bob,
who has agreed to the text being submitted under the IETF's
current copyright provisions".
3. Alice can easily find Bob's email address and he rapidly agrees
that his old contribution may be used under current IETF rules.
Alice submits a draft with the same acknowledgment as Option 2.
4. Similar, except that Bob prefers to be listed as a co-author.
Again, the normal RFC 5378 boilerplate will be used.
5. Similar, except that this would increase the number of listed
authors above the limit preferred by the RFC Editor. In this
case, a list of fully identified Contributors would be used, as
defined in the RFC Editor's Editorial Guidelines.
6. Bob doesn't reply in a reasonable period of time, or says he
doesn't agree, or says that his previous employer actually owns
the rights, and it would take months of discussion with their
lawyers to get agreement. In such cases, Alice has wasted her
time, and she reverts to Option 1 above.
The same possibilities would apply to text from an Internet-Draft
submitted prior to RFC 5378, or to text posted as email as part of an
IETF discussion prior to RFC 5378.
There is scope for judgment and common sense when using small
fragments of text, whether taken from speech, email, a draft, or an
RFC. This Appendix doesn't define rules or offer legal advice about
the copyright status of odd phrases and sentences culled from normal
ongoing IETF discussion prior to RFC 5378. However, the originators
of such fragments have the chance to complain about their use during
Working Group or IETF Last Call. Of course, when in doubt, it is
always safe to include the disclaimer.
Note that for jointly written drafts, all direct and indirect
contributors take responsibility for identifying pre-5378 text from
other contributors. If Alice submits a draft written by herself,
Alicia and Alize, all three are responsible for verifying that any
old text from other contributions that they have re-used is handled
according to this document.
What amounts to a reasonable amount of time to wait for Bob to reply,
when trying Options 3 through 6 above? There is normally no reason
to wait more than a few days. If the issue is considered unusually
important for some reason, it will be a matter of judgment how hard
Carpenter & Alvestrand Expires November 12, 2009 [Page 8]
Internet-Draft Including old text May 2009
to work on getting agreement from Bob and possibly his previous
employer. The WG Chair, the Area Director, or the IETF Trust might
be asked to assist. However, it seems likely that in most cases,
that much effort will seem excessive, and it will be fine to include
the disclaimer. It should be remembered that the IETF's ability to
do its own work is absolutely unaffected by this result.
What amounts to sufficient agreement from Bob? The IETF process
takes place mainly on-line, so a clear email agreeing to RFC 5378
conditions should be enough. However, it would be better if Bob also
provides the hard-copy general non-exclusive license suggested by the
IETF Trust. If Bob writes that he is replying on behalf of his co-
contributors, that should also be enough. But if Bob states that he
cannot speak for his previous employers, that is not enough on its
own. In many cases, employment laws or contracts do not leave Bob
with copyright in his own writings, so the previous employer's
agreement is needed. The best way for that to happen is for the
employer concerned to sign the Trust's general license. In most
cases, it probably isn't reasonable for Alice to pursue this option
herself.
It should be noted that when the disclaimer is included, the
situation for a third party wishing to re-use the old text is exactly
as it always has been: the third party has to identify the legitimate
copyright holder(s) ("Bob") and get their permission. The IETF, the
IETF Trust, and the recent contributors ("Alice") are not concerned.
The procedure defined in the main body of this document is intended
to ensure that in the case of affected documents, the contributors do
not waste their time. They, or people acting on their behalf, may
choose to make a modest and reasonable effort to gain agreement from
earlier contributors that RFC 5378 rules may be applied (basically,
checking the IETF Trust web site, and if necessary, sending "Bob" an
email). But they have a simple and straightforward default choice -
the disclaimer - which leaves all parties no worse off than under the
old rules. And in all cases, normal good practice is followed by
including an acknowledgment.
