The MirOS license is a free content license created by The MirOS Project as an alternative to licenses like the ISC license. It is based on licenses like the BSD license but aims to be more explicit and usable for European authors. The license covers any copyrightable work and has been approved by the Open Knowledge Foundation. While not formally reviewed, it is recognized as a free content license. The license aims to provide a single "copycenter-style" license that allows free use and modification without attribution requirements.
