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-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

    essentially the equivalent of this Public License.

    d. 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.

    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 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. 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.

    l. 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.

    m. 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.

            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.

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-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, 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.

    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 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.
