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

.. topic:: 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.

   * **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.

:xlarge:`Creative Commons Attribution 4.0 International 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 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.

f. **Licensed Material** means the artistic or literary work, database, or
   other material to which the Licensor applied this Public License.

g. **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.

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. :underline:`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. :underline:`Term.` The term of this Public License is specified in Section 6(a).

   4. :underline:`Media and formats`; :underline:`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. :underline:`Downstream recipients.`

       A. :underline:`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. :underline:`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. :underline:`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.
