"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. |
||||||
|
|
||||||
|
"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). |
||||||
|
|
||||||
|
"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. |
||||||
|
|
||||||
|
"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." |
||||||
|
|
||||||
|
"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. 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. 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. 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) You must give any other recipients of the Work or |
||||||
|
Derivative Works a copy of this License; and |
||||||
|
|
||||||
|
(b) You must cause any modified files to carry prominent notices |
||||||
|
stating that You changed the files; and |
||||||
|
|
||||||
|
(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) 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. |
||||||
|
