MySQL FLOSS License Exception
The MySQL AB Exception for Free/Libre and Open Source
Software-only Applications Using MySQL Client Libraries (the
"FLOSS Exception").
Version 0.5, 30 August 2006
Exception Intent
We want specified Free/Libre and Open Source Software (``FLOSS'')
applications to be able to use specified GPL-licensed MySQL client
libraries (the ``Program'') despite the fact that not all FLOSS
licenses are compatible with version 2 of the GNU General Public
License (the ``GPL'').
Legal Terms and Conditions
As a special exception to the terms and conditions of version 2.0
of the GPL:
1. You are free to distribute a Derivative Work that is formed
entirely from the Program and one or more works (each, a
"FLOSS Work") licensed under one or more of the licenses
listed below in section 1, as long as:
a. You obey the GPL in all respects for the Program and the
Derivative Work, except for identifiable sections of the
Derivative Work which are not derived from the Program,
and which can reasonably be considered independent and
separate works in themselves,
b. all identifiable sections of the Derivative Work which
are not derived from the Program, and which can
reasonably be considered independent and separate works
in themselves,
i. are distributed subject to one of the FLOSS licenses
listed below, and
ii. the object code or executable form of those sections
are accompanied by the complete corresponding
machine-readable source code for those sections on
the same medium and under the same FLOSS license as
the corresponding object code or executable forms of
those sections, and
c. any works which are aggregated with the Program or with a
Derivative Work on a volume of a storage or distribution
medium in accordance with the GPL, can reasonably be
considered independent and separate works in themselves
which are not derivatives of either the Program, a
Derivative Work or a FLOSS Work.
If the above conditions are not met, then the Program may only
be copied, modified, distributed or used under the terms and
conditions of the GPL or another valid licensing option from
MySQL AB.
2. FLOSS License List
License name Version(s)/Copyright Date
Academic Free License 2.0
Apache Software License 1.0/1.1/2.0
Apple Public Source License 2.0
Artistic license From Perl 5.8.0

Due to the many variants of some of the above licenses, we
require that any version follow the 2003 version of the Free
Software Foundation's Free Software Definition
(http://www.gnu.org/philosophy/free-sw.html) or version 1.9 of
the Open Source Definition by the Open Source Initiative
(http://www.opensource.org/docs/definition.php).
3. Definitions
a. Terms used, but not defined, herein shall have the
meaning provided in the GPL.
b. Derivative Work means a derivative work under copyright
law.
4. Applicability: This FLOSS Exception applies to all Programs
that contain a notice placed by MySQL AB saying that the
Program may be distributed under the terms of this FLOSS
Exception. If you create or distribute a work which is a
Derivative Work of both the Program and any other work
licensed under the GPL, then this FLOSS Exception is not
available for that work; thus, you must remove the FLOSS
Exception notice from that work and comply with the GPL in all
respects, including by retaining all GPL notices. You may
choose to redistribute a copy of the Program exclusively under
the terms of the GPL by removing the FLOSS Exception notice
from that copy of the Program, provided that the copy has
never been modified by you or any third party.
Appendix A. Qualified Libraries and Packages
The following is a non-exhaustive list of libraries and packages
which are covered by the FLOSS License Exception. Please note that
this appendix is provided merely as an additional service to
specific FLOSS projects wishing to simplify licensing information
for their users. Compliance with one of the licenses noted under
the "FLOSS license list" section remains a prerequisite.
