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 makes its licenses and related

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

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.

        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,

        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.

        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

        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

        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.

    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.
