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.
