Academic Free License
|
|
Version 1.2
|
|
|
|
This Academic Free License applies to any original work of authorship
|
|
(the "Original Work") whose owner (the "Licensor") has placed the
|
|
following notice immediately following the copyright notice for the
|
|
Original Work:
|
|
|
|
Licensed under the Academic Free License version 1.2
|
|
|
|
Grant of License. Licensor hereby grants to any person obtaining a
|
|
copy of the Original Work ("You") a world-wide, royalty-free,
|
|
non-exclusive, perpetual, non-sublicenseable license (1) to use, copy,
|
|
modify, merge, publish, perform, distribute and/or sell copies of the
|
|
Original Work and derivative works thereof, and (2) under patent claims
|
|
owned or controlled by the Licensor that are embodied in the Original
|
|
Work as furnished by the Licensor, to make, use, sell and offer for
|
|
sale the Original Work and derivative works thereof, subject to the
|
|
following conditions.
|
|
|
|
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.
|
|
|
|
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 written permission
|
|
of the Licensor.
|
|
|
|
Warranty and Disclaimer of Warranty. Licensor warrants that the copyright
|
|
in and to the Original Work is owned by the Licensor or that the Original
|
|
Work is distributed by Licensor under a valid current license from the
|
|
copyright owner. Except as expressly stated in the immediately proceeding
|
|
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 Original Work is granted hereunder except
|
|
under this disclaimer.
|
|
|
|
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 any person for any direct, 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 liability for death or personal
|
|
injury resulting from Licensor`s negligence to the extent applicable law
|
|
prohibits such limitation. Some jurisdictions do not allow the exclusion or
|
|
limitation of incidental or consequential damages, so this exclusion and
|
|
limitation may not apply to You.
|
|
|
|
License to Source Code. 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 hereby
|
|
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, and by
|
|
publishing the address of that information repository in a notice immediately
|
|
following the copyright notice that applies to the Original Work.
|
|
|
|
Mutual 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 if You file a lawsuit in any court alleging that any OSI
|
|
Certified open source software that is licensed under any license containing
|
|
this "Mutual Termination for Patent Action" clause infringes any patent
|
|
claims that are essential to use that software.
|
|
|
|
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.
|
|

|
Permission is hereby granted to copy and distribute this license without
|
|
modification. This license may not be modified without the express written
|
|
permission of its copyright owner.

END OF LICENSE. The following is intended to describe the essential
|
|
differences between the Academic Free License (AFL) version 1.0 and other
|
|
open source licenses:
|
|
|
|
The Academic Free License is similar to the BSD, MIT, UoI/NCSA and Apache
|
|
licenses in many respects but it is intended to solve a few problems with
|
|
those licenses.
|
|
|
|
* The AFL is written so as to make it clear what software is being
|
|
licensed (by the inclusion of a statement following the copyright notice
|
|
in the software). This way, the license functions better than a template
|
|
license. The BSD, MIT and UoI/NCSA licenses apply to unidentified software.
|
|
|
|
* The AFL contains a complete copyright grant to the software. The BSD
|
|
and Apache licenses are vague and incomplete in that respect.
|
|
|
|
* The AFL contains a complete patent grant to the software. The BSD, MIT,
|
|
UoI/NCSA and Apache licenses rely on an implied patent license and contain
|
|
no explicit patent grant.
|
|
|
|
* The AFL makes it clear that no trademark rights are granted to the
|
|
licensor`s trademarks. The Apache license contains such a provision, but the
|
|
BSD, MIT and UoI/NCSA licenses do not.
|
|
|
|
* The AFL includes the warranty by the licensor that it either owns the
|
|
copyright or that it is distributing the software under a license. None of
|
|
the other licenses contain that warranty. All other warranties are disclaimed,
|
|
as is the case for the other licenses.
|
|
|
|
* The AFL is itself copyrighted (with the right granted to copy and distribute
|
|
without modification). This ensures that the owner of the copyright to the
|
|
license will control changes. The Apache license contains a copyright notice,
|
|
but the BSD, MIT and UoI/NCSA licenses do not.
