Lino is Free software¶
The members of the Lino Community agree that the result of their work is published using a permissive Free Software license in order to make it available to everybody and to avoid vendor lock-in.
The Lino Software Foundation is dedicated to work according to these license terms and does neither prohibit nor support derivative work by non-members under other licenses.
The copyright holder for all source files of the Lino framework is Rumma & Ko Ltd. This seems the most reasonable and practical formulation as long as Rumma & Ko are the community motor. We plan to change the copyright holder to Lino Software Foundation in the future. As long as there is no legal entity to act as copyright holder, everybody must trust that Rumma & Ko will manage things correctly.
- Proprietary software
Software that is published by its copyright holder using a license which reserves to the copyright holder the right of sharing the software of derivative work.
- Free Software
Software that is published by its copyright holder using a license* which permits and encourages sharing of the software or derivative work.
Not to mix up with freeware (proprietary software distributed without fee).
Free Software licenses can be grouped into two families: permissive and protective.
- Permissive Free Software license
A Free Software license which sets minimal requirements about how the software or derivative work may be redistributed.
- Protective Free Software license
A Free Software license which requires that redistribution of derivative work is licensed under the same license.
An example is the GNU GPL.
With permissive Free software, the copyright holder has no legal means of regulating how their work is being used. The permissive license allows to write and publish derivative work even under a proprietary (non-free) license. Accordingly any other actor may start at any moment and without asking your permission to use your software and modify it for their own purpose.
Optionally the project operator may register some part of their project as a trademark.
If you contribute some code to some repository of the Lino project, we ask you to assign your copyright to Rumma & Ko Ltd because we want to avoid legal problems in case we want to change the license in the future and because we do not want to add every individual contributor to every copyright statement.
Contributor License Agreement¶
When you contribute a change to Lino, then basically you are the copyright holder of your work and you agree to publish your work under the same license as Lino and you ask us to integrate your contribution.
We did not (yet) formulate and sign any Contributor License Agreement as e.g. Django does it. Every contributor is liable for their work: if one of us would (accidentally) publish a file with sensitive confidential data or copyrighted content, only that particular person (or their employer) would be liable.
