 22Statement of Purpose
 23
 24The laws of most jurisdictions throughout the world automatically confer
 25exclusive Copyright and Related Rights (defined below) upon the creator
 26and subsequent owner(s) (each and all, an "owner") of an original work of
 27authorship and/or a database (each, a "Work").
 28
 29Certain owners wish to permanently relinquish those rights to a Work for
 30the purpose of contributing to a commons of creative, cultural and
 31scientific works ("Commons") that the public can reliably and without fear
 32of later claims of infringement build upon, modify, incorporate in other
 33works, reuse and redistribute as freely as possible in any form whatsoever
 34and for any purposes, including without limitation commercial purposes.
 35These owners may contribute to the Commons to promote the ideal of a free
 36culture and the further production of creative, cultural and scientific
 37works, or to gain reputation or greater distribution for their Work in
 38part through the use and efforts of others.
 39
 40For these and/or other purposes and motivations, and without any
 41expectation of additional consideration or compensation, the person
 42associating CC0 with a Work (the "Affirmer"), to the extent that he or she
 43is an owner of Copyright and Related Rights in the Work, voluntarily
 44elects to apply CC0 to the Work and publicly distribute the Work under its
 45terms, with knowledge of his or her Copyright and Related Rights in the
 46Work and the meaning and intended legal effect of CC0 on those rights.
 47
 481. Copyright and Related Rights. A Work made available under CC0 may be
 49protected by copyright and related or neighboring rights ("Copyright and
 50Related Rights"). Copyright and Related Rights include, but are not
 51limited to, the following:
 52
 53  i. the right to reproduce, adapt, distribute, perform, display,
 54     communicate, and translate a Work;
 55 ii. moral rights retained by the original author(s) and/or performer(s);
 56iii. publicity and privacy rights pertaining to a person's image or
 57     likeness depicted in a Work;
 58 iv. rights protecting against unfair competition in regards to a Work,
 59     subject to the limitations in paragraph 4(a), below;
 60  v. rights protecting the extraction, dissemination, use and reuse of data
 61     in a Work;
 62 vi. database rights (such as those arising under Directive 96/9/EC of the
 63     European Parliament and of the Council of 11 March 1996 on the legal
 64     protection of databases, and under any national implementation
 65     thereof, including any amended or successor version of such
 66     directive); and
 67vii. other similar, equivalent or corresponding rights throughout the
 68     world based on applicable law or treaty, and any national
 69     implementations thereof.
 70
 712. Waiver. To the greatest extent permitted by, but not in contravention
 72of, applicable law, Affirmer hereby overtly, fully, permanently,
 73irrevocably and unconditionally waives, abandons, and surrenders all of
 74Affirmer's Copyright and Related Rights and associated claims and causes
 75of action, whether now known or unknown (including existing as well as
 76future claims and causes of action), in the Work (i) in all territories
 77worldwide, (ii) for the maximum duration provided by applicable law or
 78treaty (including future time extensions), (iii) in any current or future
 79medium and for any number of copies, and (iv) for any purpose whatsoever,
 80including without limitation commercial, advertising or promotional
 81purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
 82member of the public at large and to the detriment of Affirmer's heirs and
 83successors, fully intending that such Waiver shall not be subject to
 84revocation, rescission, cancellation, termination, or any other legal or
 85equitable action to disrupt the quiet enjoyment of the Work by the public
 86as contemplated by Affirmer's express Statement of Purpose.
 87
 883. Public License Fallback. Should any part of the Waiver for any reason
 89be judged legally invalid or ineffective under applicable law, then the
 90Waiver shall be preserved to the maximum extent permitted taking into
 91account Affirmer's express Statement of Purpose. In addition, to the
 92extent the Waiver is so judged Affirmer hereby grants to each affected
 93person a royalty-free, non transferable, non sublicensable, non exclusive,
 94irrevocable and unconditional license to exercise Affirmer's Copyright and
 95Related Rights in the Work (i) in all territories worldwide, (ii) for the
 96maximum duration provided by applicable law or treaty (including future
 97time extensions), (iii) in any current or future medium and for any number
 98of copies, and (iv) for any purpose whatsoever, including without
 99limitation commercial, advertising or promotional purposes (the
100"License"). The License shall be deemed effective as of the date CC0 was
101applied by Affirmer to the Work. Should any part of the License for any
102reason be judged legally invalid or ineffective under applicable law, such
103partial invalidity or ineffectiveness shall not invalidate the remainder
104of the License, and in such case Affirmer hereby affirms that he or she
105will not (i) exercise any of his or her remaining Copyright and Related
106Rights in the Work or (ii) assert any associated claims and causes of
107action with respect to the Work, in either case contrary to Affirmer's
108express Statement of Purpose.
109
1104. Limitations and Disclaimers.

120    the greatest extent permissible under applicable law.

122    that may apply to the Work or any use thereof, including without
