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:

Creative Commons Attribution-ShareAlike 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-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 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,
   publication, distribution, public performance, public display, and
   adaptation rights, and rights in database extensions and
   collections.

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

e. Licensed Rights means 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.

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

g. 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.

h. 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.

i. 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.

      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. 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.

c. Patent and trademark rights are not licensed under this Public
   License.

d. 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.

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-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; 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 that arise 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.
