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:

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. 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.

  b. No additional 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.


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.

  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 this
     Public License.

  e. 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 as, reducing, limiting, restricting, or imposing 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.
