The MIT License is a free software license originating at the Massachusetts Institute of Technology (MIT).〔Lawrence Rosen, OPEN SOURCE LICENSING, p.85 (Prentice Hall PTR, 1st ed. 2004)〕 It is a permissive free software license, meaning that it permits reuse within proprietary software provided all copies of the licensed software include a copy of the MIT License terms and the copyright notice. Such proprietary software retains its proprietary nature even though it incorporates software under the MIT License. The license is also GPL-compatible, meaning that the GPL permits combination and redistribution with software that uses the MIT License.〔(【引用サイトリンク】title=Various Licenses and Comments about Them )〕 Notable software packages that use one of the versions of the MIT License include Expat, the Mono development platform class libraries, Ruby on Rails, Node.js, Lua (from version 5.0 onwards), jQuery and the X Window System, for which the license was written. ==Various versions== Because MIT has used many licenses for software, the Free Software Foundation considers "MIT License" ambiguous. "MIT License" may refer to the "Expat License" (used for Expat)〔(【引用サイトリンク】title=Various Licenses and Comments about Them#Expat License )〕 or to the "X11 License" (also called "MIT/X Consortium License"; used for the X Window System by the MIT X Consortium).〔(【引用サイトリンク】title=Various Licenses and Comments about Them#X11 License )〕 The "MIT License" published on the official site of Open Source Initiative〔(【引用サイトリンク】title=Open Source Initiative OSI – The MIT License:Licensing )〕 is the same as the "Expat License".
