FOSS License Exception

Updated October 9, 2008

What is the FOSS License Exception?

Sun's Free and Open Source Software ("FOSS") License Exception (formerly known as the FLOSS License Exception) allows developers of FOSS applications to include Sun's MySQL Client Libraries (also referred to as "MySQL Drivers" or "MySQL Connectors") with their FOSS applications. MySQL Client Libraries are typically licensed pursuant to version 2 of the General Public License ("GPL"), but this exception permits distribution of certain MySQL Client Libraries with a developer's FOSS applications licensed under the terms of another FOSS license listed below, even though such other FOSS license may be incompatible with the GPL.

The following terms and conditions describe the circumstances under which Sun's FOSS License Exception applies.

Sun's FOSS License Exception Terms and Conditions


"Derivative Work" means a derivative work, as defined under applicable copyright law, formed entirely from the Program and one or more FOSS Applications.

"FOSS Application" means a free and open source software application distributed subject to a license listed in the section below titled "FOSS License List."

"FOSS Notice" means a notice placed by Sun or MySQL in a copy of the MySQL Client Libraries stating that such copy of the MySQL Client Libraries may be distributed under Sun's or MySQL's FOSS (or FLOSS) License Exception.

"Independent Work" means portions of the Derivative Work that are not derived from the Program and can reasonably be considered independent and separate works.

"Program" means a copy of Sun's MySQL Client Libraries that contains a FOSS Notice.

A FOSS application developer ("you" or "your") may distribute a Derivative Work provided that you and the Derivative Work meet all of the following conditions:

  • • You obey the GPL in all respects for the Program and all portions (including modifications) of the Program included in the Derivative Work (provided that this condition does not apply to Independent Works);
  • • The Derivative Work does not include any work licensed under the GPL other than the Program;
  • • You distribute Independent Works subject to a license listed in the section below titled "FOSS License List";
  • • You distribute Independent Works in object code or executable form with the complete corresponding machine-readable source code on the same medium and under the same FOSS license applying to the object code or executable forms;

All works that are aggregated with the Program or the Derivative Work on a medium or volume of storage are not derivative works of the Program, Derivative Work or FOSS Application, and must reasonably be considered independent and separate works.

Sun reserves all rights not expressly granted in these terms and conditions. If all of the above conditions are not met, then this FOSS License Exception does not apply to you or your Derivative Work.
