Transitive Grace Period Public Licence ("TGPPL") v. 1.0
|
||||||
|
=======================================================
|
||||||
|
|
||||||
|
This Transitive Grace Period Public Licence (the "License") applies to any
|
||||||
|
original work of authorship (the "Original Work") whose owner (the
|
||||||
|
"Licensor") has placed the following licensing notice adjacent to the
|
||||||
|
copyright notice for the Original Work:
|
||||||
|
|
||||||
|
*Licensed under the Transitive Grace Period Public Licence version 1.0*
|
||||||
|
|
||||||
|
1. **Grant of Copyright License.** Licensor grants You a worldwide,
|
||||||
|
royalty-free, non-exclusive, sublicensable license, for the duration of
|
||||||
|
the copyright, to do the following:
|
||||||
|
|
||||||
|
a. to reproduce the Original Work in copies, either alone or as part of a
|
||||||
|
collective work;
|
||||||
|
|
||||||
|
b. to translate, adapt, alter, transform, modify, or arrange the Original
|
||||||
|
Work, thereby creating derivative works ("Derivative Works") based upon
|
||||||
|
the Original Work;
|
||||||
|
|
||||||
|
c. to distribute or communicate copies of the Original Work and Derivative
|
||||||
|
Works to the public, with the proviso that copies of Original Work or
|
||||||
|
Derivative Works that You distribute or communicate shall be licensed
|
||||||
|
under this Transitive Grace Period Public Licence no later than 12
|
||||||
|
months after You distributed or communicated said copies;
|
||||||
|
|
||||||
|
d. to perform the Original Work publicly; and
|
||||||
|
|
||||||
|
e. to display the Original Work publicly.
|
||||||
|
|
||||||
|
2. **Grant of Patent License.** Licensor grants You a worldwide,
|
||||||
|
royalty-free, non-exclusive, sublicensable license, under patent claims
|
||||||
|
owned or controlled by the Licensor that are embodied in the Original
|
||||||
|
Work as furnished by the Licensor, for the duration of the patents, to
|
||||||
|
make, use, sell, offer for sale, have made, and import the Original Work
|
||||||
|
and Derivative Works.
|
||||||
|
|
||||||
|
3. **Grant of Source Code License.** The term "Source Code" means the
|
||||||
|
preferred form of the Original Work for making modifications to it and
|
||||||
|
all available documentation describing how to modify the Original
|
||||||
|
Work. Licensor agrees to provide a machine-readable copy of the Source
|
||||||
|
Code of the Original Work along with each copy of the Original Work that
|
||||||
|
Licensor distributes. Licensor reserves the right to satisfy this
|
||||||
|
obligation by placing a machine-readable copy of the Source Code in an
|
||||||
|
information repository reasonably calculated to permit inexpensive and
|
||||||
|
convenient access by You for as long as Licensor continues to distribute
|
||||||
|
the Original Work.
|
||||||
|
|
||||||
|
4. **Exclusions From License Grant.** Neither the names of Licensor, nor the
|
||||||
|
names of any contributors to the Original Work, nor any of their
|
||||||
|
trademarks or service marks, may be used to endorse or promote products
|
||||||
|
derived from this Original Work without express prior permission of the
|
||||||
|
Licensor. Except as expressly stated herein, nothing in this License
|
||||||
|
grants any license to Licensor's trademarks, copyrights, patents, trade
|
||||||
|
secrets or any other intellectual property. No patent license is granted
|
||||||
|
to make, use, sell, offer for sale, have made, or import embodiments of
|
||||||
|
any patent claims other than the licensed claims defined in Section 2. No
|
||||||
|
license is granted to the trademarks of Licensor even if such marks are
|
||||||
|
included in the Original Work. Nothing in this License shall be
|
||||||
|
interpreted to prohibit Licensor from licensing under terms different
|
||||||
|
from this License any Original Work that Licensor otherwise would have a
|
||||||
|
right to license.
|
||||||
|
|
||||||
|
5. **External Deployment.** The term "External Deployment" means the use,
|
||||||
|
distribution, or communication of the Original Work or Derivative Works
|
||||||
|
in any way such that the Original Work or Derivative Works may be used by
|
||||||
|
anyone other than You, whether those works are distributed or
|
||||||
|
communicated to those persons or made available as an application
|
||||||
|
intended for use over a network. As an express condition for the grants
|
||||||
|
of license hereunder, You must treat any External Deployment by You of
|
||||||
|
the Original Work or a Derivative Work as a distribution under section
|
||||||
|
1(c).
|
||||||
|
|
||||||
|
6. **Attribution Rights.** You must retain, in the Source Code of any
|
||||||
|
Derivative Works that You create, all copyright, patent, or trademark
|
||||||
|
notices from the Source Code of the Original Work, as well as any notices
|
||||||
|
of licensing and any descriptive text identified therein as an
|
||||||
|
"Attribution Notice." You must cause the Source Code for any Derivative
|
||||||
|
Works that You create to carry a prominent Attribution Notice reasonably
|
||||||
|
calculated to inform recipients that You have modified the Original Work.
|
||||||
|
|
||||||
|
7. **Warranty of Provenance and Disclaimer of Warranty.** Licensor warrants
|
||||||
|
that the copyright in and to the Original Work and the patent rights
|
||||||
|
granted herein by Licensor are owned by the Licensor or are sublicensed
|
||||||
|
to You under the terms of this License with the permission of the
|
||||||
|
contributor(s) of those copyrights and patent rights. Except as expressly
|
||||||
|
stated in the immediately preceding sentence, the Original Work is
|
||||||
|
provided under this License on an "AS IS" BASIS and WITHOUT WARRANTY,
|
||||||
|
either express or implied, including, without limitation, the warranties
|
||||||
|
of non-infringement, merchantability or fitness for a particular
|
||||||
|
purpose. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK IS WITH
|
||||||
|
YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this
|
||||||
|
License. No license to the Original Work is granted by this License
|
||||||
|
except under this disclaimer.
|
||||||
|
|
||||||
|
8. **Limitation of Liability.** Under no circumstances and under no legal
|
||||||
|
theory, whether in tort (including negligence), contract, or otherwise,
|
||||||
|
shall the Licensor be liable to anyone for any indirect, special,
|
||||||
|
incidental, or consequential damages of any character arising as a result
|
||||||
|
of this License or the use of the Original Work including, without
|
||||||
|
limitation, damages for loss of goodwill, work stoppage, computer failure
|
||||||
|
or malfunction, or any and all other commercial damages or losses. This
|
||||||
|
limitation of liability shall not apply to the extent applicable law
|
||||||
|
prohibits such limitation.
|
||||||
|
|
||||||
|
9. **Acceptance and Termination.** If, at any time, You expressly assented
|
||||||
|
to this License, that assent indicates your clear and irrevocable
|
||||||
|
acceptance of this License and all of its terms and conditions. If You
|
||||||
|
distribute or communicate copies of the Original Work or a Derivative
|
||||||
|
Work, You must make a reasonable effort under the circumstances to obtain
|
||||||
|
the express assent of recipients to the terms of this License. This
|
||||||
|
License conditions your rights to undertake the activities listed in
|
||||||
|
Section 1, including your right to create Derivative Works based upon the
|
||||||
|
Original Work, and doing so without honoring these terms and conditions
|
||||||
|
is prohibited by copyright law and international treaty. Nothing in this
|
||||||
|
License is intended to affect copyright exceptions and limitations
|
||||||
|
(including 'fair use' or 'fair dealing'). This License shall terminate
|
||||||
|
immediately and You may no longer exercise any of the rights granted to
|
||||||
|
You by this License upon your failure to honor the conditions in Section
|
||||||
|
1(c).
|
||||||
|
|
||||||
|
10. **Termination for Patent Action.** This License shall terminate
|
||||||
|
automatically and You may no longer exercise any of the rights granted to
|
||||||
|
You by this License as of the date You commence an action, including a
|
||||||
|
cross-claim or counterclaim, against Licensor or any licensee alleging
|
||||||
|
that the Original Work infringes a patent. This termination provision
|
||||||
|
shall not apply for an action alleging patent infringement by
|
||||||
|
combinations of the Original Work with other software or hardware.
|
||||||
|
|
||||||
|
11. **Jurisdiction, Venue and Governing Law.** Any action or suit relating to
|
||||||
|
this License may be brought only in the courts of a jurisdiction wherein
|
||||||
|
the Licensor resides or in which Licensor conducts its primary business,
|
||||||
|
and under the laws of that jurisdiction excluding its conflict-of-law
|
||||||
|
provisions. The application of the United Nations Convention on Contracts
|
||||||
|
for the International Sale of Goods is expressly excluded. Any use of the
|
||||||
|
Original Work outside the scope of this License or after its termination
|
||||||
|
shall be subject to the requirements and penalties of copyright or patent
|
||||||
|
law in the appropriate jurisdiction. This section shall survive the
|
||||||
|
termination of this License.
|
||||||
|
|
||||||
|
12. **Attorneys' Fees.** In any action to enforce the terms of this License
|
||||||
|
or seeking damages relating thereto, the prevailing party shall be
|
||||||
|
entitled to recover its costs and expenses, including, without
|
||||||
|
limitation, reasonable attorneys' fees and costs incurred in connection
|
||||||
|
with such action, including any appeal of such action. This section shall
|
||||||
|
survive the termination of this License.
|
||||||
|
|
||||||
|
13. **Miscellaneous.** If any provision of this License is held to be
|
||||||
|
unenforceable, such provision shall be reformed only to the extent
|
||||||
|
necessary to make it enforceable.
|
||||||
|
|
||||||
|
14. **Definition of "You" in This License.** "You" throughout this License,
|
||||||
|
whether in upper or lower case, means an individual or a legal entity
|
||||||
|
exercising rights under, and complying with all of the terms of, this
|
||||||
|
License. For legal entities, "You" includes any entity that controls, is
|
||||||
|
controlled by, or is under common control with you. For 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.
|
||||||
|
|
||||||
|
15. **Right to Use.** You may use the Original Work in all ways not otherwise
|
||||||
|
restricted or conditioned by this License or by law, and Licensor
|
||||||
|
promises not to interfere with or be responsible for such uses by You.
|
||||||
|
|
||||||
|
16. **Modification of This License.** This License is Copyright © 2007 Zooko
|
||||||
|
Wilcox-O'Hearn. Permission is granted to copy, distribute, or communicate
|
||||||
|
this License without modification. Nothing in this License permits You to
|
||||||
|
modify this License as applied to the Original Work or to Derivative
|
||||||
|
Works. However, You may modify the text of this License and copy,
|
||||||
|
distribute or communicate your modified version (the "Modified License")
|
||||||
|
and apply it to other original works of authorship subject to the
|
||||||
|
following conditions: (i) You may not indicate in any way that your
|
||||||
|
Modified License is the "Transitive Grace Period Public Licence" or
|
||||||
|
"TGPPL" and you may not use those names in the name of your Modified
|
||||||
|
License; and (ii) You must replace the notice specified in the first
|
||||||
|
paragraph above with the notice "Licensed under <insert your license name
|
||||||
|
here>" or with a notice of your own that is not confusingly similar to
|
||||||
|
the notice in this License.
