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

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 <http://wiki.creativecommons.org/Considerations_for_licensors_and_licensees#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 for the
   public <http://wiki.creativecommons.org/Considerations_for_licensors_and_licensees#Considerations_for_licensees>`__.

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

   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

   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,

i. **Licensed Rights** means the rights granted to You subject to the

   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

   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,

   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

   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.
