Creative Commons Corporation ("Creative Commons") is not a law firm and
|
|
||||||
does not provide legal services or legal advice. Distribution of
|
|

Creative Commons public licenses does not create a lawyer-client or

other relationship. Creative Commons makes its licenses and related

information available on an "as-is" basis. Creative Commons gives no

|
|
||||||
Using Creative Commons Public Licenses
|
|
||||||
|
|
||||||
Creative Commons public licenses provide a standard set of terms and
|
|
||||||
conditions that creators and other rights holders may use to share
|
|
||||||
original works of authorship and other material subject to copyright
|
|
||||||
and certain other rights specified in the public license below. The
|
|
||||||
following considerations are for informational purposes only, are not
|
|
||||||
exhaustive, and do not form part of our licenses.
|
|
||||||
|
|
||||||
Considerations for licensors: Our public licenses are
|
|
||||||
intended for use by those authorized to give the public
|
|
||||||
permission to use material in ways otherwise restricted by
|
|
||||||
copyright and certain other rights. Our licenses are
|
|
||||||
irrevocable. Licensors should read and understand the terms
|
|
||||||
and conditions of the license they choose before applying it.
|
|
||||||
Licensors should also secure all rights necessary before
|
|
||||||
applying our licenses so that the public can reuse the
|
|
||||||
material as expected. Licensors should clearly mark any
|
|
||||||
material not subject to the license. This includes other CC-
|
|
||||||
licensed material, or material used under an exception or
|
|
||||||
limitation to copyright. More considerations for licensors:
|
|
||||||
wiki.creativecommons.org/Considerations_for_licensors
|
|
||||||
|
|
||||||
Considerations for the public: By using one of our public
|
|
||||||
licenses, a licensor grants the public permission to use the
|
|
||||||
licensed material under specified terms and conditions. If
|
|
||||||
the licensor's permission is not necessary for any reason--for
|
|
||||||
example, because of any applicable exception or limitation to
|
|
||||||
copyright--then that use is not regulated by the license. Our
|
|
||||||
licenses grant only permissions under copyright and certain
|
|
||||||
other rights that a licensor has authority to grant. Use of
|
|
||||||
the licensed material may still be restricted for other
|
|
||||||
reasons, including because others have copyright or other
|
|
||||||
rights in the material. A licensor may make special requests,
|
|
||||||
such as asking that all changes be marked or described.
|
|
||||||
Although not required by our licenses, you are encouraged to
|
|
||||||
respect those requests where reasonable. More_considerations

|

Section 2 -- Scope.
|
|
||||||
|
|
||||||
a. License grant.
|
|
||||||
|
|
||||||
1. Subject to the terms and conditions of this Public License,
|
|
||||||
the Licensor hereby grants You a worldwide, royalty-free,
|
|
||||||
non-sublicensable, non-exclusive, irrevocable license to
|
|
||||||
exercise the Licensed Rights in the Licensed Material to:
|
|
||||||
|
|
||||||
a. reproduce and Share the Licensed Material, in whole or
|
|
||||||
in part; and
|
|
||||||
|
|
||||||
b. produce, reproduce, and Share Adapted Material.
|
|
||||||
|
|
||||||
2. Exceptions and Limitations. For the avoidance of doubt, where
|
|
||||||
Exceptions and Limitations apply to Your use, this Public
|
|
||||||
License does not apply, and You do not need to comply with
|
|
||||||
its terms and conditions.
|
|
||||||
|
|
||||||
3. Term. The term of this Public License is specified in Section
|
|
||||||
6(a).
|
|
||||||
|
|
||||||
4. Media and formats; technical modifications allowed. The
|
|
||||||
Licensor authorizes You to exercise the Licensed Rights in
|
|
||||||
all media and formats whether now known or hereafter created,
|
|
||||||
and to make technical modifications necessary to do so. The
|
|
||||||
Licensor waives and/or agrees not to assert any right or
|
|
||||||
authority to forbid You from making technical modifications
|
|
||||||
necessary to exercise the Licensed Rights, including
|
|
||||||
technical modifications necessary to circumvent Effective
|
|
||||||
Technological Measures. For purposes of this Public License,
|
|
||||||
simply making modifications authorized by this Section 2(a)
|
|
||||||
(4) never produces Adapted Material.
|
|
||||||
|
|
||||||
5. Downstream recipients.
|
|
||||||
|
|
||||||
a. Offer from the Licensor -- Licensed Material. Every
|
|
||||||
recipient of the Licensed Material automatically
|
|
||||||
receives an offer from the Licensor to exercise the
|
|
||||||
Licensed Rights under the terms and conditions of this
|
|
||||||
Public License.
|
|
||||||
|
|
||||||
b. Additional offer from the Licensor -- Adapted Material.
|
|
||||||
Every recipient of Adapted Material from You
|
|
||||||
automatically receives an offer from the Licensor to
|
|
||||||
exercise the Licensed Rights in the Adapted Material
|
|
||||||
under the conditions of the Adapter's License You apply.
|
|
||||||
|
|
||||||
c. No downstream restrictions. You may not offer or impose
|
|
||||||
any additional or different terms or conditions on, or
|
|
||||||
apply any Effective Technological Measures to, the
|
|
||||||
Licensed Material if doing so restricts exercise of the
|
|
||||||
Licensed Rights by any recipient of the Licensed
|
|
||||||
Material.
|
|
||||||
|
|
||||||
6. No endorsement. Nothing in this Public License constitutes or
|
|
||||||
may be construed as permission to assert or imply that You
|
|
||||||
are, or that Your use of the Licensed Material is, connected
|
|
||||||
with, or sponsored, endorsed, or granted official status by,
|
|
||||||
the Licensor or others designated to receive attribution as
|
|
||||||
provided in Section 3(a)(1)(A)(i).
|
|
||||||
|
|
||||||
b. Other rights.
|
|
||||||
|
|
||||||
1. Moral rights, such as the right of integrity, are not
|
|
||||||
licensed under this Public License, nor are publicity,
|
|
||||||
privacy, and/or other similar personality rights; however, to
|
|
||||||
the extent possible, the Licensor waives and/or agrees not to
|
|
||||||
assert any such rights held by the Licensor to the limited
|
|
||||||
extent necessary to allow You to exercise the Licensed
|
|
||||||
Rights, but not otherwise.
|
|
||||||
|
|
||||||
2. Patent and trademark rights are not licensed under this
|
|
||||||
Public License.
|
|
||||||
|
|
||||||
3. To the extent possible, the Licensor waives any right to
|
|
||||||
collect royalties from You for the exercise of the Licensed
|
|
||||||
Rights, whether directly or through a collecting society
|
|
||||||
under any voluntary or waivable statutory or compulsory
|
|
||||||
licensing scheme. In all other cases the Licensor expressly
|
|
||||||
reserves any right to collect such royalties.
|
|
||||||
|
|
||||||
|
|
||||||
Section 3 -- License Conditions.
|
|
||||||

|
||||||

|
||||||

|
|
||||||

|
||||||
attribution, in any reasonable manner requested by

||||||
the Licensor (including by pseudonym if
|
|
||||||

|
||||||
|
|
||||||
ii. a copyright notice;

|
||||||
|

||||||
|

||||||
v. a URI or hyperlink to the Licensed Material to the
|
|
||||||
extent reasonably practicable;
|
|
||||||
|
|
||||||
b. indicate if You modified the Licensed Material and
|
|
||||||
retain an indication of any previous modifications; and
|
|
||||||
|
|
||||||
c. indicate the Licensed Material is licensed under this
|
|
||||||
Public License, and include the text of, or the URI or
|
|
||||||
hyperlink to, this Public License.
|
|
||||||
|
|
||||||
2. You may satisfy the conditions in Section 3(a)(1) in any
|
|
||||||
reasonable manner based on the medium, means, and context in
|
|
||||||
which You Share the Licensed Material. For example, it may be
|
|
||||||
reasonable to satisfy the conditions by providing a URI or
|
|
||||||
hyperlink to a resource that includes the required
|
|
||||||
information.
|
|
||||||
|
|
||||||
3. If requested by the Licensor, You must remove any of the
|
|
||||||
information required by Section 3(a)(1)(A) to the extent
|
|
||||||
reasonably practicable.
|
|
||||||
|
|
||||||
b. ShareAlike.
|
|
||||||
|
|
||||||
In addition to the conditions in Section 3(a), if You Share
|
|
||||||
Adapted Material You produce, the following conditions also apply.
|
|
||||||
|
|
||||||
1. The Adapter's License You apply must be a Creative Commons
|
|
||||||
license with the same License Elements, this version or
|
|
||||||
later, or a BY-SA Compatible License.
|
|
||||||
|
|
||||||
2. You must include the text of, or the URI or hyperlink to, the
|
|
||||||
Adapter's License You apply. You may satisfy this condition
|
|
||||||
in any reasonable manner based on the medium, means, and
|
|
||||||
context in which You Share Adapted Material.
|
|
||||||
|
|
||||||
3. You may not offer or impose any additional or different terms
|
|
||||||
or conditions on, or apply any Effective Technological
|
|
||||||
Measures to, Adapted Material that restrict exercise of the
|
|
||||||
rights granted under the Adapter's License You apply.
|
|
||||||
|
|
||||||
|
|
||||||
Section 4 -- Sui Generis Database Rights.
|
|
||||||
|
|
||||||
Where the Licensed Rights include Sui Generis Database Rights that
|
|
||||||
apply to Your use of the Licensed Material:
|
|
||||||
|
|
||||||
a. for the avoidance of doubt, Section 2(a)(1) grants You the right
|
|
||||||
to extract, reuse, reproduce, and Share all or a substantial
|
|
||||||
portion of the contents of the database;
|
|
||||||
|
|
||||||
b. if You include all or a substantial portion of the database
|
|
||||||
contents in a database in which You have Sui Generis Database
|
|
||||||
Rights, then the database in which You have Sui Generis Database
|
|
||||||
Rights (but not its individual contents) is Adapted Material,
|
|
||||||
|
|
||||||
including for purposes of Section 3(b); and
|
|
||||||
c. You must comply with the conditions in Section 3(a) if You Share
|
|
||||||
all or a substantial portion of the contents of the database.
|
|
||||||
|
|
||||||
For the avoidance of doubt, this Section 4 supplements and does not
|
|
||||||
replace Your obligations under this Public License where the Licensed
|
|
||||||
Rights include other Copyright and Similar Rights.
|
|
||||||
|
|
||||||
|
|
||||||
Section 5 -- Disclaimer of Warranties and Limitation of Liability.
|
|
||||||
|
|
||||||
a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
|
|
||||||
EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
|
|
||||||
AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
|
|
||||||
ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
|
|
||||||
IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
|
|
||||||
WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
|
|
||||||
PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
|
|
||||||
ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
|
|
||||||
KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
|
|
||||||
ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
|
|
||||||
|
|
||||||
b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
|
|
||||||
TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
|
|
||||||
NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
|
|
||||||
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
|
|
||||||
COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
|
|
||||||
USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
|
|
||||||
ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
|
|
||||||
DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
|
|
||||||
IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
|
|
||||||
|
|
||||||
c. The disclaimer of warranties and limitation of liability provided
|
|
||||||
above shall be interpreted in a manner that, to the extent
|
|
||||||
possible, most closely approximates an absolute disclaimer and
|
|
||||||
waiver of all liability.
|
|
||||||
|
|
||||||
|
|
||||||
Section 6 -- Term and Termination.
|
|
||||||
|
|
||||||
a. This Public License applies for the term of the Copyright and
|
|
||||||
Similar Rights licensed here. However, if You fail to comply with
|
|
||||||
this Public License, then Your rights under this Public License
|
|
||||||
terminate automatically.
|
|
||||||
|
|
||||||
b. Where Your right to use the Licensed Material has terminated under
|
|
||||||
Section 6(a), it reinstates:
|
|
||||||
|
|
||||||
1. automatically as of the date the violation is cured, provided
|
|
||||||
it is cured within 30 days of Your discovery of the
|
|
||||||
violation; or
|
|
||||||
|
|
||||||
2. upon express reinstatement by the Licensor.
|
|
||||||
|
|
||||||
For the avoidance of doubt, this Section 6(b) does not affect any
|
|
||||||
right the Licensor may have to seek remedies for Your violations
|
|
||||||
of this Public License.
|
|
||||||
|
|
||||||
c. For the avoidance of doubt, the Licensor may also offer the
|
|
||||||
Licensed Material under separate terms or conditions or stop
|
|
||||||
distributing the Licensed Material at any time; however, doing so
|
|
||||||
will not terminate this Public License.
|
|
||||||
|
|
||||||
d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
|
|
||||||
License.

|
||||||
|
|
||||||
|
|
||||||
Section 7 -- Other Terms and Conditions.

terms or conditions communicated by You unless expressly agreed.
|
|
||||||

|
|

a. For the avoidance of doubt, this Public License does not, and
|
|
||||||
shall not be interpreted to, reduce, limit, restrict, or impose
|
|
||||||
conditions on any use of the Licensed Material that could lawfully
|

be made without permission under this Public License.

|
||||||
deemed unenforceable, it shall be automatically reformed to the
|
|
||||||
minimum extent necessary to make it enforceable. If the provision
|
|
||||||
cannot be reformed, it shall be severed from this Public License
|
|
||||||
without affecting the enforceability of the remaining terms and
|
|
||||||
conditions.
|

||||||
|
|
||||||
c. No term or condition of this Public License will be waived and no
|
|
||||||
failure to comply consented to unless expressly agreed to by the
|
|
||||||
Licensor.
|
|
||||||
|
|
||||||
d. Nothing in this Public License constitutes or may be interpreted
|
|
||||||
as a limitation upon, or waiver of, any privileges and immunities
|
|
||||||
that apply to the Licensor or You, including from the legal
|
|
||||||
processes of any jurisdiction or authority.
