1  CC0 1.0 Universal
  2  
  3  Statement of Purpose
  4  
  5  The laws of most jurisdictions throughout the world automatically confer
  6  exclusive Copyright and Related Rights (defined below) upon the creator and
  7  subsequent owner(s) (each and all, an "owner") of an original work of
  8  authorship and/or a database (each, a "Work").
  9  
 10  Certain owners wish to permanently relinquish those rights to a Work for the
 11  purpose of contributing to a commons of creative, cultural and scientific
 12  works ("Commons") that the public can reliably and without fear of later
 13  claims of infringement build upon, modify, incorporate in other works, reuse
 14  and redistribute as freely as possible in any form whatsoever and for any
 15  purposes, including without limitation commercial purposes. These owners may
 16  contribute to the Commons to promote the ideal of a free culture and the
 17  further production of creative, cultural and scientific works, or to gain
 18  reputation or greater distribution for their Work in part through the use and
 19  efforts of others.
 20  
 21  For these and/or other purposes and motivations, and without any expectation
 22  of additional consideration or compensation, the person associating CC0 with a
 23  Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
 24  and Related Rights in the Work, voluntarily elects to apply CC0 to the Work
 25  and publicly distribute the Work under its terms, with knowledge of his or her
 26  Copyright and Related Rights in the Work and the meaning and intended legal
 27  effect of CC0 on those rights.
 28  
 29  1. Copyright and Related Rights. A Work made available under CC0 may be
 30  protected by copyright and related or neighboring rights ("Copyright and
 31  Related Rights"). Copyright and Related Rights include, but are not limited
 32  to, the following:
 33  
 34    i. the right to reproduce, adapt, distribute, perform, display, communicate,
 35    and translate a Work;
 36  
 37    ii. moral rights retained by the original author(s) and/or performer(s);
 38  
 39    iii. publicity and privacy rights pertaining to a person's image or likeness
 40    depicted in a Work;
 41  
 42    iv. rights protecting against unfair competition in regards to a Work,
 43    subject to the limitations in paragraph 4(a), below;
 44  
 45    v. rights protecting the extraction, dissemination, use and reuse of data in
 46    a Work;
 47  
 48    vi. database rights (such as those arising under Directive 96/9/EC of the
 49    European Parliament and of the Council of 11 March 1996 on the legal
 50    protection of databases, and under any national implementation thereof,
 51    including any amended or successor version of such directive); and
 52  
 53    vii. other similar, equivalent or corresponding rights throughout the world
 54    based on applicable law or treaty, and any national implementations thereof.
 55  2. Waiver. To the greatest extent permitted by, but not in contravention of,
 56  applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
 57  unconditionally waives, abandons, and surrenders all of Affirmer's Copyright
 58  and Related Rights and associated claims and causes of action, whether now
 59  known or unknown (including existing as well as future claims and causes of
 60  action), in the Work (i) in all territories worldwide, (ii) for the maximum
 61  duration provided by applicable law or treaty (including future time
 62  extensions), (iii) in any current or future medium and for any number of
 63  copies, and (iv) for any purpose whatsoever, including without limitation
 64  commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes
 65  the Waiver for the benefit of each member of the public at large and to the
 66  detriment of Affirmer's heirs and successors, fully intending that such Waiver
 67  shall not be subject to revocation, rescission, cancellation, termination, or
 68  any other legal or equitable action to disrupt the quiet enjoyment of the Work
 69  by the public as contemplated by Affirmer's express Statement of Purpose.
 70  
 71  3. Public Licence Fallback. Should any part of the Waiver for any reason be
 72  judged legally invalid or ineffective under applicable law, then the Waiver
 73  shall be preserved to the maximum extent permitted taking into account
 74  Affirmer's express Statement of Purpose. In addition, to the extent the Waiver
 75  is so judged Affirmer hereby grants to each affected person a royalty-free,
 76  non transferable, non sublicensable, non exclusive, irrevocable and
 77  unconditional licence to exercise Affirmer's Copyright and Related Rights in
 78  the Work (i) in all territories worldwide, (ii) for the maximum duration
 79  provided by applicable law or treaty (including future time extensions), (iii)
 80  in any current or future medium and for any number of copies, and (iv) for any
 81  purpose whatsoever, including without limitation commercial, advertising or
 82  promotional purposes (the "Licence"). The Licence shall be deemed effective as
 83  of the date CC0 was applied by Affirmer to the Work. Should any part of the
 84  Licence for any reason be judged legally invalid or ineffective under
 85  applicable law, such partial invalidity or ineffectiveness shall not
 86  invalidate the remainder of the Licence, and in such case Affirmer hereby
 87  affirms that he or she will not (i) exercise any of his or her remaining
 88  Copyright and Related Rights in the Work or (ii) assert any associated claims
 89  and causes of action with respect to the Work, in either case contrary to
 90  Affirmer's express Statement of Purpose.
 91  
 92  4. Limitations and Disclaimers.
 93  
 94    a. No trademark or patent rights held by Affirmer are waived, abandoned,
 95    surrendered, licenced or otherwise affected by this document.
 96  
 97    b. Affirmer offers the Work as-is and makes no representations or warranties
 98    of any kind concerning the Work, express, implied, statutory or otherwise,
 99    including without limitation warranties of title, merchantability, fitness
100    for a particular purpose, non infringement, or the absence of latent or
101    other defects, accuracy, or the present or absence of errors, whether or not
102    discoverable, all to the greatest extent permissible under applicable law.
103  
104    c. Affirmer disclaims responsibility for clearing rights of other persons
105    that may apply to the Work or any use thereof, including without limitation
106    any person's Copyright and Related Rights in the Work. Further, Affirmer
107    disclaims responsibility for obtaining any necessary consents, permissions
108    or other rights required for any use of the Work.
109  
110    d. Affirmer understands and acknowledges that Creative Commons is not a
111    party to this document and has no duty or obligation with respect to this
112    CC0 or use of the Work.
