MIT 开源协议

MIT许可证（The MIT License）是许多软件受权条款中，被普遍使用的其中一种。与其余常见的软件受权条款（如GPL、LGPL、BSD）相比，MIT是相对宽松的软件受权条款。

简介

MIT许可证之名源自麻省理工学院（Massachusetts Institute of Technology, MIT），又称“X条款”（X License）或“X11条款”（X11 License） MIT内容与三条款BSD许可证（3-clause BSD license）内容颇为近似，可是赋予软件被受权人更大的权利与更少的限制。 运用情形

有许多团体均采用MIT许可证。例如著名的ssh链接软件PuTTY与X Windows System (X11)即为例子。Expat, Mono开发平台库，Ruby on Rails, Lua 5.0 onwards等等也都采用MIT受权条款。 条款内容

IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.[2] 被受权人权利

被受权人有权利使用、复制、修改、合并、出版发行、散布、再受权及贩售软件及软件的副本。 被受权人可根据程序的须要修改受权条款为适当的内容。 被受权人义务

在软件和软件的全部副本中都必须包含版权声明和许可声明。 其余重要特性

此受权条款并不是属copyleft的自由软件受权条款，容许在自由/开放源码软件或非自由软件（proprietary software）所使用。 MIT的内容可依照程序著做权者的需求更改内容。此亦为MIT与BSD（The BSD license, 3-clause BSD license）本质上不一样处。 MIT条款可与其余受权条款并存。另外，MIT条款也是自由软件基金会（FSF）所承认的自由软件受权条款，与GPL兼容。 MI协议模板
