FOSS License Exceptions

What is the FOSS License Exception?

This Free and Open Source Software ("FOSS") License Exception allows developers of FOSS applications to include hamsterdb with their FOSS applications. hamsterdb is typically licensed pursuant to version 2 (or later) of the General Public License ("GPL"), but this exception permits distribution of hamsterdb with a developers 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 this FOSS License Exception applies.

FOSS License Exception Terms and Conditions

   1. Definitions.
      "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 the hamsterdb author in a copy 
      of the hamsterdb Libraries stating that such copy of the hamsterdb 
      Library may be distributed under hamsterdb'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 hamsterdb Libraries that contains a 
      FOSS Notice.

   2. 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:
         1. You obey the GPL 2 (or later) 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);
         2. The Derivative Work does not include any work licensed under the 
            GPL other than the Program;
         3. You distribute Independent Works subject to a license listed in 
            the section below titled "FOSS License List";
         4. 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;
         5. 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.

   3. The hamsterdb author 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.
