Copyright Policy

Praxes uses a shared copyright model. Each contributor maintains copyright over their contributions to Praxes. These contributions are typically changes (diffs/commits) to the repositories. The source code in its entirety is not the copyright of any single person or institution. Instead, it is the collective copyright of the entire Praxes Development Team. Individual contributors wishing to maintain a record of contributions to which they hold specific copyright should indicate their copyright in the commit message of the change to the repository.

Any new code contributed to Praxes must be licensed under the BSD license or a similar (MIT) open source license.

Miscellaneous

Praxes is built upon PyQt4 and dip, which are provided by Riverbank Computing (http://www.riverbankcomputing.com/news) under the terms of the GNU Public License. Riverbank Computing explicitly grants additional rights to license such derived work under the terms of the BSD license (among others). This allows Praxes to be developed and distributed under the terms of the BSD license. Commercial projects can be derived from Praxes, but if such a project continues to derive from PyQt4, a commercial license is required from Riverbank Computing.
