-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

-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-NonCommercial-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

-sound recording, and Sui Generis Database Rights, without regard to how the
-rights are labeled or categorized. For purposes of this Public License, the

-
-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,
-NonCommercial, and ShareAlike.
-
-h. Licensed Material means the artistic or literary work, database, or other
-material to which the Licensor applied this Public License.
-
-i. Licensed Rights means the rights granted to You subject to the terms and
-conditions of this Public License, which are limited to all Copyright and
-Similar Rights that apply to Your use of the Licensed Material and that the
-Licensor has authority to license.
-
-j. Licensor means the individual(s) or entity(ies) granting rights under this
-Public License.
-
-k. NonCommercial means not primarily intended for or directed towards commercial
-advantage or monetary compensation. For purposes of this Public License, the
-exchange of the Licensed Material for other material subject to Copyright
-and Similar Rights by digital file-sharing or similar means is NonCommercial
-provided there is no payment of monetary compensation in connection with the
-exchange.
-
-l. 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

-that members of the public may access the material from a place and at a time
-individually chosen by them.
-
-m. Sui Generis Database Rights means rights other than copyright resulting
-from Directive 96/9/EC of the European Parliament and of the Council of 11
-March 1996 on the legal protection of databases, as amended and/or succeeded,

-
-n. You means the individual or entity exercising the Licensed Rights under

-
-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, for NonCommercial
-purposes only; and
-
-B. produce, reproduce, and Share Adapted Material for NonCommercial purposes
-only.
-
-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, including when the Licensed Material is used other
-than for NonCommercial purposes.
-
-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-NC-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 for NonCommercial purposes only;
-
-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.

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

-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.
-

-Commons may elect to apply one of its public licenses to material it publishes
-and in those instances will be considered the "Licensor." The text of the
