# CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE

|
||||||
|
#
|
||||||
|
# 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.
