-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 :

-
-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 :

-Attribution-ShareAlike 4.0 International Public License ("Public
-License"). To the extent this Public License may be interpreted as a

- 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

- 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

- 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.

- 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);

- 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.

- 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.
-
- c. 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.
-
- d. 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

- 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.
