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.
