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").
