By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution-NonCommercial-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 Similar Rights in Your contributions to Adapted Material in
accordance with the terms and conditions of this Public License.

c. BY-NC-SA Compatible License means a license listed at
creativecommons.org/compatiblelicenses, approved by Creative
Commons 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, NonCommercial, 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. NonCommercial means not primarily intended for or directed towards
commercial advantage or monetary compensation. For purposes of
this Public License, the exchange of the Licensed Material for
other material subject to Copyright and Similar Rights by digital
file-sharing or similar means is NonCommercial provided there is
no payment of monetary compensation in connection with the
exchange.

l. 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.

m. 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.

n. 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, for NonCommercial purposes only; and

        b. produce, reproduce, and Share Adapted Material for
           NonCommercial purposes only.

   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, including when
      the Licensed Material is used other than for NonCommercial
      purposes.

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-NC-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 for NonCommercial purposes
only;

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.
