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

other relationship. Creative Commons makes its licenses and related

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:

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

Creative Commons Attribution-ShareAlike 4.0 International Public

License

By exercising the Licensed Rights (defined below), You accept and agree

to be bound by the terms and conditions of this Creative Commons

Attribution-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-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 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. 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.

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.

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.
