Section 2 --- Scope.

\begin{enumerate}
    \item License grant.
    \begin {enumerate}
        \item 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:
        \begin{enumerate}
            \item reproduce and Share the Licensed Material, in whole or 
            in part; and
            \item produce, reproduce, and Share Adapted Material.
        \end{enumerate}
        \item 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.
        \item Term . The term of this Public License is specified in 
        Section 6(a) .
        \item 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.
        \item Downstream recipients.
        \begin{enumerate}
            \item 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.
            \item 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.
            \item 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.
        \end{enumerate}
        \item 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).
    \end{enumerate}
    \item Other rights.
    \begin{enumerate}
        \item 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.
        \item Patent and trademark rights are not licensed under this 
        Public License.
        \item 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.
    \end{enumerate}
\end{enumerate}

Section 3 --- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the 
following conditions.

\begin{enumerate}
    \item Attribution.
    \begin {enumerate}

        \item If You Share the Licensed Material (including in modified 
        form), You must:
        \begin {enumerate}
            \item retain the following if it is supplied by the Licensor
            with the Licensed Material:
            \begin{enumerate}
                \item 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);
                \item a copyright notice;
                \item a notice that refers to this Public License;
                \item a notice that refers to the disclaimer of 
                warranties;
                \item a URI or hyperlink to the Licensed Material to the 
                extent reasonably practicable;
            \end{enumerate}
            \item indicate if You modified the Licensed Material and 
            retain an indication of any previous modifications; and
            \item indicate the Licensed Material is licensed under this 
            Public License, and include the text of, or the URI or 
            hyperlink to, this Public License.
        \end{enumerate}
        \item 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.
        \item If requested by the Licensor, You must remove any of the 
        information required by Section 3(a)(1)(A) to the extent 
        reasonably practicable.
    \end{enumerate}
    \item ShareAlike.

    In addition to the conditions in Section 3(a), if You Share Adapted 
    Material You produce, the following conditions also apply.
    
    \begin{enumerate}
        \item 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.
        \item 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.
        \item 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.
    \end{enumerate}
\end{enumerate}

Section 4 – Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply 
to Your use of the Licensed Material:

\begin{enumerate}
    \item 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;
    \item 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
    \item You must comply with the conditions in Section 3(a) if You 
    Share all or a substantial portion of the contents of the database.
\end{enumerate}

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.

\begin{enumerate}
    \item 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.
    \item 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.
    \item 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.
\end{enumerate}

Section 6 --- Term and Termination.

\begin{enumerate}
    \item 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.

    \item Where Your right to use the Licensed Material has terminated 
    under Section 6(a), it reinstates:
    \begin{enumerate}
        \item automatically as of the date the violation is cured, 
        provided it is cured within 30 days of Your discovery of the 
        violation; or
        \item upon express reinstatement by the Licensor.
    \end{enumerate}

    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.
    \item 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.
    \item Sections 1, 5, 6, 7, and 8 survive termination of this 
    Public License.
\end{enumerate}

Section 7 – Other Terms and Conditions.

\begin{enumerate}
    \item The Licensor shall not be bound by any additional or different 
    terms or conditions communicated by You unless expressly agreed.
    \item 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.
\end{enumerate}

Section 8 – Interpretation.

\begin{enumerate}
    \item 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.
    \item 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.
    \item 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.
    \item 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.
\end{enumerate}
