The IETF requires that certain notices and disclaimers described in
this Section 5 be reproduced verbatim in all IETF Documents
(including copies, derivative works and translations of IETF
Documents, but subject to the limited exceptions noted in Section
5.2). This requirement protects IETF and its participants from
liabilities connected with these documents. The copyright notice
also alerts readers that the document is an IETF Document, and that
ISOC claims copyright rights to certain aspects of the document, such
as its layout, the RFC numbering convention and the prefatory
language of the document. This legend is not intended to imply that
ISOC has obtained ownership of the IETF Contribution itself, which is
retained by the author(s) or remains in the public domain, as
applicable.
Each IETF Document must include the required notices described in
this Section 5. The required notices are the following:
a. The IPR Disclosure Acknowledgement described in Section 5.1
(required in all Internet-Drafts).
b. The Derivative Works Limitation described in Section 5.2 (for
specific IETF Documents only).
c. The Publication Limitation described in Section 5.3 (for specific
types of Internet-Drafts only).
d. The Copyright Notice described in Section 5.4 (for all IETF
Documents).
e. The Disclaimer described in Section 5.5 (for all IETF Documents).
5.1. IPR Disclosure Acknowledgement (required in all Internet-Drafts only)
"By submitting this Internet-Draft, I certify that any applicable
patent or other IPR claims of which I am aware have been disclosed,
and any of which I become aware will be disclosed, in accordance with
RFC 3668(-> 3979)."
5.2. Derivative Works Limitation
If the Contributor desires to eliminate the IETF's right to make
modifications and derivative works of an IETF Contribution (other
than translations), one of the two of the following notices may be
included in the Status of Memo section of an Internet-Draft and
included in a published RFC:
a. "This document may not be modified, and derivative works of it may
not be created, except to publish it as an RFC and to translate it
into languages other than English."
b. "This document may not be modified, and derivative works of it may
not be created."
In the cases of MIB or PIB modules and in other cases where the
Contribution includes material that is meant to be extracted in order
to be used, the following should be appended to statement 5.2 (a) or
5.2 (b):
"other than to extract section XX as-is for separate use."
Notice 5.2(a) is used if the Contributor intends for the IETF
Contribution to be published as an RFC. Notice 5.2(b) is used along
with the Publication Limitation in Section 5.3 when the Contributor
does not intend for the IETF Contribution to be published as an RFC.
These notices may not be used with any standards-track document or
with most working group documents, except as discussed in Section 7.3
below, since the IETF must retain change control over its documents
and the ability to augment, clarify and enhance the original IETF
Contribution in accordance with the IETF Standards Process.
Notice 5.2(a) may be appropriate when republishing standards produced
by other (non-IETF) standards organizations, industry consortia or
companies. These are typically published as Informational RFCs, and
do not require that change control be ceded to the IETF. Basically,
documents of this type convey information for the Internet community.
A fuller discussion of the rationale behind these requirements is
contained in Section 7.3 below.
5.3. Publication Limitation
If the Contributor only wants the IETF Contribution to be made
available in an Internet-Draft (i.e., does not want the IETF
Contribution to be published as an RFC) then the Contributor may
include the following notice in the Status of Memo section of the
Internet-Draft.
"This document may only be posted in an Internet-Draft."
This notice can be used on IETF Contributions that are intended to
provide background information to educate and to facilitate
discussions within IETF working groups but are not intended to be
published as an RFCs.
5.4. Copyright Notice (required for all IETF Documents)
(Normally placed at the end of the IETF Document.)
"Copyright (C) The Internet Society (year). This document is
subject to the rights, licenses and restrictions contained in BCP
78, and except as set forth therein, the authors retain all their
rights."
Additional copyright notices are not permitted in IETF Documents
except in the case where such document is the product of a joint
development effort between the IETF and another standards development
organization or the document is a republication of the work of
another standards organization. Such exceptions must be approved on
an individual basis by the IAB.
5.5. Disclaimer (required in all IETF Documents)
(Normally placed at the end of the IETF Document after the copyright
notice.)
"This document and the information contained herein are provided
on an "AS IS" basis and THE CONTRIBUTOR, THE ORGANIZATION HE/SHE
REPRESENTS OR IS SPONSORED BY (IF ANY), THE INTERNET SOCIETY AND
THE INTERNET ENGINEERING TASK FORCE DISCLAIM ALL WARRANTIES,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTY THAT
THE USE OF THE INFORMATION HEREIN WILL NOT INFRINGE ANY RIGHTS OR
ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE."
5.6. Exceptions
Notwithstanding the provisions of this Section 5, in certain limited
cases an abbreviated notice may be placed on certain types of
derivative works of IETF Documents in accordance with this Section
5.6.
a. in MIB modules, PIB modules and similar material commonly
extracted from IETF Documents, except for material that is being
placed under IANA maintenance, the following abbreviated notice
shall be included in the body of the material that will be
extracted in lieu of the notices otherwise required by Section 5:
"Copyright (C) The Internet Society <year> . This version of
this MIB module is part of RFC XXXX; see the RFC itself for
full legal notices."
When the MIB or PIB module is the initial version of a module that
is to be maintained by the IANA, the following abbreviated notice
shall be included:
"Copyright (C) The Internet Society <year>. The initial
version of this MIB module was published in RFC XXXX; for full
legal notices see the RFC itself. Supplementary information
may be available on
http://www.ietf.org/copyrights/ianamib.html."
For other types of components than "MIB", substitute "MIB module"
with an appropriate identifier. In the case of MIB and PIB
modules this statement should be placed in the DESCRIPTION clause
of the MODULE-IDENTITY macro.
Variations of these abbreviated notices are not permitted except
in cases where the material to be extracted is the product of a
joint development effort between the IETF and another standards
development organization or is a republication of the work of
another standards organization. Such variations must be approved
on an individual basis by the IAB.
b. short excerpts of IETF Documents presented in electronic help
systems, for example, the DESCRIPTION clauses for MIB variables,
do not need to include a copyright notice.
