Multiple licences and KAboutData

Hi,

I am preparing to relicence the code of Okteta to GPL v2/v3/v" any later
accepted by KDE e.V. body".

But this gives me trouble with KAboutData:
KAboutData just allows to set one licence "setLicense (LicenseKey
licenseKey)". Was this done on purpose? Or should I sit down and develop a
patch for KAboutData which allows multiple licences?

Friedrich

I would have thought that "any later accepted by KDE e.V. body" is something t
hat doesn't really belong in KAboutData.  It's there so that the KDE codebase
can be re-licensed en masse to later versions of the GPL without finding every
copyright holder.

However, I think multiple licensing is a good thing to allow.  So we can say "
this is licensed under both GPLv2 and GPLv3, and you can choose either".

So when the membership of KDE e.V. accepts a new license, all files with that
option will need to get an explicit mentioning of the license anyway, which
includes also adding the information to the about data for the about dialog,
instead of reading it automatically from somewhere in kdelibs? Might be a
good idea to keep it this way, as the licenses of all files should be checked
before, if not some code slipped in which does not have that license option.

Any idea how this could be presented to the user? The patch I sent to
kde-core-devel just lists all licenses without any additional explanation
(see http://frinring.files.wordpress.com/2008/02/aboutokteta.png). No "or"
mentioned. Is that needed at all?

Dual-licensing typically (ie: pretty much always) means you can use any of the
licenses you like, as long as you satisfy the conditions.  I think anyone who
is really interested in the license will realise this.

So I don't think any further explanation is necessary.

Alright. Patch is committed now, so everyone can furtherone state multiple
licenses also in the gui.

Thanks
