By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution 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 acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and 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 Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.

b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.

c. 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.

d. 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.

e. 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.

h. Licensor means the individual(s) or entity(ies) granting rights under this Public License.

i. 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.

j. 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, as well as other essentially equivalent rights anywhere in the world.

k. 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. __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.

4. If You Share Adapted Material You produce, the Adapter's License You
   apply must not prevent recipients of the Adapted Material from complying
   with this Public License.

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; 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.

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

b. Any arrangements, understandings, or agreements regarding the 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.
