TheAcademic Free License (AFL) is apermissive free software license written in 2002 byLawrence E. Rosen, a formergeneral counsel of theOpen Source Initiative (OSI).

The license grants similar rights to theBSD,MIT,UoI/NCSA andApache licenses – licenses allowing the software to be madeproprietary – 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;
  • includes a complete copyright grant to the software;
  • contains a complete patent grant to the software;
  • makes clear that no trademark rights are granted to the licensor's trademarks;
  • warrants that the licensor either owns the copyright or is distributing the software under a license;
  • is itself copyrighted, with the right granted to copy and distribute without modification.

TheFree Software Foundation consider all AFL versions up to and including 3.0 asincompatible with theGNU GPL.[1] thoughEric S. Raymond (a co-founder of the OSI) contends that AFL 3.0 is GPL compatible.[3] In late 2002, an OSI working draft considered it a "best practice" license.[4] In mid-2006, however, the OSI'sLicense Proliferation Committee found it "redundant with more popular licenses",[2] specifically version 2 of theApache Software License.
