The ISC license is a permissive free software license written by the Internet Systems Consortium (ISC). It is meant to be functionally equivalent to the simplified BSD and MIT licenses, differing in its removal of language deemed unnecessary following the global adoption of the Berne convention.[nb 1][nb 2] Initially used for ISC's own software releases, it has since become the preferred license of projects such as OpenBSD[3][4] and Node.js's npm.[5][6]

Text[edit]

A template of this license is:

ISC License

Copyright (c) [year(s)], [copyright holder]

Permission to use, copy, modify, and/or distribute this software for any purpose with or without fee is hereby granted, provided that the above copyright notice and this permission notice appear in all copies.

THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS.

History[edit]

Before accepting the license as a free software license, the Free Software Foundation asked for clarification of the text.[citation needed] In July 2007, as a result, "and distribute" was changed to "and/or distribute".[7] The Free Software Foundation eventually approved the ISC license as a lax, permissive free software license, compatible with the GNU GPL.[8] As of May 2016, The OpenBSD template still uses the original "and distribute" phrasing,[3] due to concerns about the modified version.[nb 3]

Footnotes[edit]

  1. ^ "The ISC copyright is functionally equivalent to a two-term BSD copyright with language removed that is made unnecessary by the Berne convention."[1]
  2. ^ "In OpenBSD we use an ISC-style copyright text [...] that is enough to satisfy every legal system on the planet which follows the Berne Convention."[2]
  3. ^ "Watch out for the new ISC license, because the FSF lawyers have convinced the ISC to [use the] phrase "and/or" to mean "or", but some country's legal systems might not understand "and/or" in the way the old "or" was used in the sentence. I disagree with what ISC did; I am not confident that their change is good."[2]
