ISC Licence

Description

A very permissive license expressly designed to replace the various versions of the MIT, PostgreSQL and BSD licenses with something that has clearer and simpler text but is functionally identical. It takes out parts that are references to rights and grants that are already implicit in the Berne Convention and therefore automatically granted anyway, it makes no sense to include those in a license as even the USA has been bound by the Berne Convention for more than 40 years, and their inclusion can lead to confusion.

The main functional difference between it and the various BSD like licenses is that "this permission notice appear in all copies" is clearer and more definite than the "Redistributions of source code must retain the above copyright notice" etc., which may be interpreted so as forks or works that do only use parts of the code are not redistributions and therefore not bound to include the license and this understanding is often used by the GNU folks to justify their removal of BSD copyright and replacement of license. The "disclaimer less" version of the One Clause BSD License effectively copies the ISC license in this regard, and make note of the term differences of the original text and the "disclaimer less" version.

Note that the license text below is here for reference purposes and unlike other material on the EDM/2 Wiki is not under the Attribution-ShareAlike 3.0 license and should be treated under its own terms, or if an addition by the combined terms of the addition and the license that it is an addition to. As it is a license with fixed terms the text below it should not be modified except for formatting purposes, if a more recent version is published a new page should be created for that license since software packages that do not get updated will continue to be governed by the terms of the older license.
