CC0 1.0 Universal
|
||||
|
||||
Statement of Purpose
|
||||
|
||||
The laws of most jurisdictions throughout the world automatically confer
|
||||
exclusive Copyright and Related Rights (defined below) upon the creator and
|
||||
subsequent owner(s) (each and all, an "owner") of an original work of
|
||||
authorship and/or a database (each, a "Work").
|
||||
|
||||
Certain owners wish to permanently relinquish those rights to a Work for the
|
||||
purpose of contributing to a commons of creative, cultural and scientific
|
||||
works ("Commons") that the public can reliably and without fear of later
|
||||
claims of infringement build upon, modify, incorporate in other works, reuse
|
||||
and redistribute as freely as possible in any form whatsoever and for any
|
||||
purposes, including without limitation commercial purposes. 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. Limitations and Disclaimers.
|
||||
|
||||
a. No trademark or patent rights held by Affirmer are waived, abandoned,
|
||||
surrendered, licensed or otherwise affected by this document.
|
||||
|
||||
b. Affirmer offers the Work as-is and makes no representations or warranties
|
||||
of any kind concerning the Work, express, implied, statutory or otherwise,
|
||||
including without limitation warranties of title, merchantability, fitness
|
||||
for a particular purpose, non infringement, or the absence of latent or
|
||||
other defects, accuracy, or the present or absence of errors, whether or not
|
||||
discoverable, all to the greatest extent permissible under applicable law.
|
||||
|
||||
c. Affirmer disclaims responsibility for clearing rights of other persons
|
||||
that may apply to the Work or any use thereof, including without limitation
|
||||
any person's Copyright and Related Rights in the Work. Further, Affirmer
|
||||
disclaims responsibility for obtaining any necessary consents, permissions
|
||||
or other rights required for any use of the Work.
|
||||
|
||||
d. Affirmer understands and acknowledges that Creative Commons is not a
|
||||
party to this document and has no duty or obligation with respect to this
|
||||
CC0 or use of the Work.
