-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
- for the public:

-License
-
-By exercising the Licensed Rights (defined below), You accept and agree
-to be bound by the terms and conditions of this Creative Commons
-Attribution-ShareAlike 4.0 International Public License ("Public
-License"). To the extent this Public License may be interpreted as a
-contract, You are granted the Licensed Rights in consideration of Your

-conditions.
-
-
-Section 1 -- Definitions.
-
- a. Adapted Material means material subject to Copyright and Similar
- Rights that is derived from or based upon the Licensed Material
- and in which the Licensed Material is translated, altered,
- arranged, transformed, or otherwise modified in a manner requiring
- permission under the Copyright and Similar Rights held by the

- and Similar Rights in Your contributions to Adapted Material in
- accordance with the terms and conditions of this Public License.

- Commons as essentially the equivalent of this Public License.
-
- d. Copyright and Similar Rights means copyright and/or similar rights
- closely related to copyright including, without limitation,
- performance, broadcast, sound recording, and Sui Generis Database
- Rights, without regard to how the rights are labeled or
- categorized. For purposes of this Public License, the rights
- specified in Section 2(b)(1)-(2) are not Copyright and Similar
- Rights.
-
- e. Effective Technological Measures means those measures that, in the
- absence of proper authority, may not be circumvented under laws
- fulfilling obligations under Article 11 of the WIPO Copyright
- Treaty adopted on December 20, 1996, and/or similar international
- agreements.
-
- f. Exceptions and Limitations means fair use, fair dealing, and/or
- any other exception or limitation to Copyright and Similar Rights
- that applies to Your use of the Licensed Material.
-
- g. License Elements means the license attributes listed in the name
- of a Creative Commons Public License. The License Elements of this
- Public License are Attribution and ShareAlike.

- j. Licensor means the individual(s) or entity(ies) granting rights
- under this Public License.
-
- k. Share means to provide material to the public by any means or
- process that requires permission under the Licensed Rights, such
- as reproduction, public display, public performance, distribution,
- dissemination, communication, or importation, and to make material
- available to the public including in ways that members of the
- public may access the material from a place and at a time
- individually chosen by them.
-
- l. Sui Generis Database Rights means rights other than copyright
- resulting from Directive 96/9/EC of the European Parliament and of

- as amended and/or succeeded, as well as other essentially
- equivalent rights anywhere in the world.
-
- m. You means the individual or entity exercising the Licensed Rights
- under this Public License. Your has a corresponding meaning.
-
-
-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.
-
-Your exercise of the Licensed Rights is expressly made subject to the
-following conditions.
-
- a. Attribution.
-
- 1. If You Share the Licensed Material (including in modified
- form), You must:
-
- a. retain the following if it is supplied by the Licensor
- with the Licensed Material:
-
- i. identification of the creator(s) of the Licensed
- Material and any others designated to receive
- attribution, in any reasonable manner requested by
- the Licensor (including by pseudonym if
- designated);
-
- ii. a copyright notice;
-
- iii. a notice that refers to this Public License;
-
- iv. a notice that refers to the disclaimer of
- warranties;
-
- 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.
-

-
- a. The Licensor shall not be bound by any additional or different
- terms or conditions communicated by You unless expressly agreed.
-

- Licensed Material not stated herein are separate from and
- independent of the terms and conditions of this Public License.
-
-
-Section 8 -- Interpretation.
-
- 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.
-
- b. To the extent possible, if any provision of this Public License is
- 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.
