The Academic Free License (AFL) is a permissive free software license written in 2002 by Lawrence E. Rosen, then general counsel of the Open Source Initiative (OSI).
The license grants similar rights to the BSD, MIT, UoI/NCSA and Apache licenses — licenses allowing the software to be made proprietary — but was written to correct perceived problems with those licenses:
- The AFL makes clear what software is being licensed by including a statement following the software's copyright notice;
- The AFL includes a complete copyright grant to the software;
- The AFL contains a complete patent grant to the software;
- The AFL makes clear that no trademark rights are granted to the licensor's trademarks;
- The AFL warrants that the licensor either owns the copyright or is distributing the software under a license;
- The AFL is itself copyrighted, with the right granted to copy and distribute without modification.
AFL versions 1.2 and 2.1 are not compatible with the GNU GPL.[1] The Free Software Foundation does not consider version 3.0 to be compatible with the GPL[1], though Eric S. Raymond (a co-founder of the OSI) contends it is GPL compatible.[citation needed] In late 2002, an OSI working draft considered it a "best practice" license.[3] In mid 2006, however, the OSI's License Proliferation Committee found it "redundant with more popular licenses"[2], specifically version 2 of the Apache Software License.
