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").
