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.
