Guidelines and HOWTOs/Relicensing/KDE Relicensing
KDE GNU FDL Relicensing effort
KDE is moving new documentation to CC-BY-SA 4.0 license starting July 2017.
So that existing documentation under the GNU FDL works can continue to be mixed in with it we would like to ask for permission from rights holders to relicence it as CC-BY-SA 4.0.
Add yourself and anyone you can ask to the relicense script https://invent.kde.org/sdk/kde-dev-scripts/-/blob/master/relicensecheck.pl
KDE GPL v2.0 Relicensing effort
Why does it matter?
A couple of KDE software dependent projects or even libraries have moved or are going to move to GPLv3.
Unfortunately, GPL v3 is incompatible with GPL v2. This means that it is not possible to create a project linking GPL v2 and v3 code together. There is no problem for projects which are licensed GPLv2+ (version 2 or above).
A few pieces of KDE software are currently licensed as GPLv2 only. So far we have no reason to believe that this was something other than an oversight. However, we still need to validate with the individual copyright holders that a relicense to GPLv2+ or GPLv2+v3 is okay with them.
Therefore, in an effort we're trying to identify the contributors that have contributed under the terms of GPLv2 and where the "+" part was not explicitly mentioned. If we know that all contributors agreed to a relicense, we can go ahead and flip the license of the individual source file.
How can I help?
By identifying a contributor who as contributed under the terms of GPLv2 (use relicensecheck.pl on the file in question), and contacting him if he wasn't already contacted. Ask him the following questions:
- Are you okay with relicensing your contributions done under "GPLv2" to "GPLv2 or later"?
- Are you okay with relicensing your contributions done under "GPLv2" to "GPLv2 or GPLv3" ?
- Are you okay with relicensing your contributions done under "LGPLv2" to "LGPLv2 or later"?
- Are you okay with relicensing your contributions done under "LGPLv2" to "LGPLv2 or LGPLv3"?
- Are you okay with the KDE e.V. deciding on a future licensing change to your code, should that be necessary?
What's next?
- you checkout the kde-dev-scripts repository from https://invent.kde.org/sdk/kde-dev-scripts/-/blob/master/relicensecheck.pl
- you run relicensecheck.pl on the file or directory in question
- you interpret the result. check each commit that is being complained about carefully. Try to get the copyright's holder's permission. If you get it, update the whitelist in the script.
- review the list of declared copyright holders in the file.
- if you're all clear, change the license to the most liberal license possible. Document your change verbosely in the commit log.
Current Reply List
- The table below is generated from the script kde-dev-scripts/relicensecheck.pl, and exists only for documentation purpose. Ideally, just modify that script. Otherwise, get someone to modify the script for you.
- The empty cells mean we don't know, we asked before this option was available.
