Using Creative Commons and Open Software Licenses

Balancing the rights of creators and users, open licenses grant users some permissions to use and distribute a copyrighted work.

MIT License

The MIT License was first developed at the Massachusetts Institute of Technology (MIT) in the late 1980s. The exact origins MIT license are bit of mystery. Like the Apache 2.0, and BSD family of licenses the MIT License is a permissive software license that places few restrictions of reuse. Users of software using an MIT License are permitted to use, copy, modify, merge publish, distribute, sublicense and sell copies of the software. Some notable projects use the MIT License including Ruby on Rails, and the X Windows System.

MIT License Conditions

The MIT License is relatively simple and short. Below is the text of the MIT License from the Open Software Initiative.

are including in all copies or any substantial portions of the software.

MIT License Compatibility

The MIT License is highly compatible with other permissive licenses. Including the BSD family of licenses. It is generally compatible with  GNU GPL group of licenses. However if you distribute the code that contains or is derivative of GNU GPL code the final project must of GPL compliant. In other words any source code must of publicly available. 

MIT License, Patents

The MIT License was developed before patenting software was a common practice in the U.S. It therefore does not contain an express patent license. The broad nature of the license in general, is considered by some to encompass an implicit waiver of patent rights. If you are concerned about patent rights, the Apache 2.0 license contains an explicit contributor's patent license.

MIT No Attribution License (MIT-0)

The MIT No Attribution License is a Public Domain equivalent license it is similar to the  BSD Free license.
