 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

 as 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

 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,

 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.

   D. 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.
