The Academic Free License (AFL) is a permissive free software license written in 2002 by Lawrence E. Rosen, 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:
AFL versions 1.2 and 2.1 are not compatible with the GNU GPL.[1] The Free Software Foundation has not commented on the newer version 3.0, which Eric S. Raymond contends is GPL compatible. In late 2002, an OSI working draft considered it a "best practice" license.[2] In mid 2006, however, the OSI's License Proliferation Committee found it "redundant with more popular licenses"[3], specifically version 2 of the Apache Software License.
