Statement of Purpose

The laws of most jurisdictions throughout the world automatically confer

exclusive Copyright and Related Rights (defined below) upon the creator

and subsequent owner(s) (each and all, an "owner") of an original work

of authorship and/or a database (each, a "Work").

Certain owners wish to permanently relinquish those rights to a Work for

the purpose of contributing to a commons of creative, cultural and

scientific works ("Commons") that the public can reliably and without

fear of later claims of infringement build upon, modify, incorporate in

other works, reuse and redistribute as freely as possible in any form

whatsoever and for any purposes, including without limitation commercial

purposes. These owners may contribute to the Commons to promote the

ideal of a free culture and the further production of creative, cultural

and scientific works, or to gain reputation or greater distribution for

their Work in part through the use and efforts of others.

For these and/or other purposes and motivations, and without any

expectation of additional consideration or compensation, the person

associating CC0 with a Work (the "Affirmer"), to the extent that he or

she is an owner of Copyright and Related Rights in the Work, voluntarily

elects to apply CC0 to the Work and publicly distribute the Work under

its terms, with knowledge of his or her Copyright and Related Rights in

the Work and the meaning and intended legal effect of CC0 on those

rights.

1. Copyright and Related Rights.

A Work made available under CC0 may be protected by copyright and

related or neighboring rights ("Copyright and Related Rights").

Copyright and Related Rights include, but are not limited to, the

following:

i. the right to reproduce, adapt, distribute, perform, display,

communicate, and translate a Work;

ii. moral rights retained by the original author(s) and/or

performer(s);

iii. publicity and privacy rights pertaining to a person's image or

likeness depicted in a Work;

iv. rights protecting against unfair competition in regards to a

Work, subject to the limitations in paragraph 4(a), below;

v. rights protecting the extraction, dissemination, use and reuse of

data in a Work;

vi. database rights (such as those arising under Directive 96/9/EC

of the European Parliament and of the Council of 11 March 1996 on

the legal protection of databases, and under any national

implementation thereof, including any amended or successor version

of such directive); and

vii. other similar, equivalent or corresponding rights throughout

the world based on applicable law or treaty, and any national

implementations thereof.

2. Waiver.

To the greatest extent permitted by, but not in contravention of,

applicable law, Affirmer hereby overtly, fully, permanently,

irrevocably and unconditionally waives, abandons, and surrenders all

of Affirmer's Copyright and Related Rights and associated claims and

causes of action, whether now known or unknown (including existing as

well as future claims and causes of action), in the Work (i) in all

territories worldwide, (ii) for the maximum duration provided by

applicable law or treaty (including future time extensions), (iii) in

any current or future medium and for any number of copies, and (iv)

for any purpose whatsoever, including without limitation commercial,

advertising or promotional purposes (the "Waiver"). Affirmer makes

the Waiver for the benefit of each member of the public at large and

to the detriment of Affirmer's heirs and successors, fully intending

that such Waiver shall not be subject to revocation, rescission,

cancellation, termination, or any other legal or equitable action to

disrupt the quiet enjoyment of the Work by the public as contemplated

by Affirmer's express Statement of Purpose.

3. Public License Fallback.

Should any part of the Waiver for any reason be judged legally

invalid or ineffective under applicable law, then the Waiver shall be

preserved to the maximum extent permitted taking into account

Affirmer's express Statement of Purpose. In addition, to the extent

the Waiver is so judged Affirmer hereby grants to each affected

person a royalty-free, non transferable, non sublicensable, non

exclusive, irrevocable and unconditional license to exercise

Affirmer's Copyright and Related Rights in the Work

(i) in all territories worldwide,

(ii) for the maximum duration provided by applicable law or treaty

(including future time extensions),

(iii) in any current or future medium and for any number of copies,

and

(iv) for any purpose whatsoever, including without limitation

commercial, advertising or promotional purposes (the "License").

The License shall be deemed effective as of the date CC0 was applied

by Affirmer to the Work. Should any part of the License for any

reason be judged legally invalid or ineffective under applicable law,

such partial invalidity or ineffectiveness shall not invalidate the

remainder of the License, and in such case Affirmer hereby affirms

that he or she will not

(i) exercise any of his or her remaining Copyright and Related Rights

in the Work or

(ii) assert any associated claims and causes of action with respect

to the Work, in either case contrary to Affirmer's express Statement

of Purpose.

4. Limitations and Disclaimers.

a. No trademark or patent rights held by Affirmer are waived,

abandoned, surrendered, licensed or otherwise affected by this

document.

b. Affirmer offers the Work as-is and makes no representations or

warranties of any kind concerning the Work, express, implied,

statutory or otherwise, including without limitation warranties of

title, merchantability, fitness for a particular purpose, non

infringement, or the absence of latent or other defects, accuracy,

or the present or absence of errors, whether or not discoverable,

all to the greatest extent permissible under applicable law.

c. Affirmer disclaims responsibility for clearing rights of other

persons that may apply to the Work or any use thereof, including

without limitation any person's Copyright and Related Rights in the

Work. Further, Affirmer disclaims responsibility for obtaining any

necessary consents, permissions or other rights required for any use

of the Work.

d. Affirmer understands and acknowledges that Creative Commons is

not a party to this document and has no duty or obligation with

respect to this CC0 or use of the Work.
