Industrial Erlang User Group announces the license change to Apache License 2.0
Erlang/OTP 18.0 has been released by Ericsson today. Starting from OTP 18.0, Erlang/OTP will be released under Apache License 2.0.
The Industrial Erlang User Group initiated and maintained a constructive dialogue with the Erlang/OTP team at Ericsson in an effort to transit from the Erlang Public License to the Apache License 2.0. Starting from OTP 18.0, Erlang is licensed under the open-source Apache License 2.0. The IEUG does not own the copyright to any of the Erlang source code. The copyrights are retained by the organizations and individuals that contributed the code, mainly Ericsson AB.
For most users, the details of the license are irrelevant. All of the licenses grant permission to use, modify, and redistribute the code in a non-restrictive way. For Erlang, an open and commonly accepted license means adoption at a wider and global level. The Erlang Public License was a derivative work of the Mozilla Public License (MPL) that contained different jurisdiction terms that are in accordance with the laws of Sweden. While the Apache License 2.0 is well known and compliant with the Open Source Definition approved by the Open Source Initiative.
The license change to Apache License 2.0 is a major milestone in IEUG’s mission:
“Discuss the licensing model for Erlang to ensure its future commercial success and adoption by a wider industry segment.”
“It is never too late to take steps in the right direction, and we feel that this is an important one. Not just for the User Group, but the future health of Erlang.” says Mike Williams, co-creator of Erlang and current chairman of IEUG. “The User Group will continue to serve as a major forum where we work together with Ericsson, as we continue to move towards an Erlang Foundation when we take on new member companies.”
