Statement of Purpose
|
||||
|
||||
TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||
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").
|
||||
|
||||
1. Definitions.
|
||||
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.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
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.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by
|
||||
the copyright owner that is granting the License.
|
||||
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:
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
i. the right to reproduce, adapt, distribute, perform, display, communicate,
|
||||
and translate a Work;
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
ii. moral rights retained by the original author(s) and/or performer(s);
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
iii. publicity and privacy rights pertaining to a person's image or likeness
|
||||
depicted in a Work;
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
iv. rights protecting against unfair competition in regards to a Work,
|
||||
subject to the limitations in paragraph 4(a), below;
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
v. rights protecting the extraction, dissemination, use and reuse of data in
|
||||
a Work;
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
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
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
vii. other similar, equivalent or corresponding rights throughout the world
|
||||
based on applicable law or treaty, and any national implementations thereof.
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
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.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
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.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
4. Limitations and Disclaimers.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
a. No trademark or patent rights held by Affirmer are waived, abandoned,
|
||||
surrendered, licensed or otherwise affected by this document.
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
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.
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
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.
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
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.
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||

||||
