# Permission to Relicense under MPLv2 or BSD
|
|
|
|
Most of pyzmq is licensed under [3-Clause BSD](https://opensource.org/licenses/BSD-3-Clause).
|
|
For historical reasons, the 'core' of pyzmq (the low-level Cython bindings)
|
|
is licensed under LGPLv3, like libzmq itself.
|
|
|
|
libzmq is in the process of moving away from LGPL to the [Mozilla Public License, version
|
|
2](https://www.mozilla.org/en-US/MPL/2.0/).
|
|
I'd like to take this opportunity to follow libzmq's example and also eliminate LGPL from pyzmq.
|
|
For a similarly copyleft license, MPLv2 can be used for the core.
|
|
However, I would prefer to update the core to follow the example of the rest of pyzmq,
|
|
and adopt the 3-Clause BSD license.
|
|
|
|
This directory collects grants from individuals and firms that hold
|
|
copyrights in pyzmq to permit licensing the pyzmq code under
|
|
the MPLv2 or BSD license. See
|
|
the [0MQ Licensing Page](http://zeromq.org/area:licensing) and
|
|
[libzmq relicensing effort](https://github.com/zeromq/libzmq/pull/1917)
|
|
for some background information.
|
|
|
|
Please create a separate file in this directory for each individual
|
|
or firm holding copyright in pyzmq core, named after the individual or
|
|
firm holding the copyright.
|
|
|
|
Each patch must be made with a GitHub handle that is clearly
|
|
associated with the copyright owner, to guarantee the identity of
|
|
the signatory. Please avoid changing the files created by other
|
|
individuals or firms granting a copyright license over their
|
|
copyrights (if rewording is required contact them and ask them to
|
|
submit an updated version). This makes it easier to verify that
|
|
the license grant was made by an authorized GitHub account.
