All the data we want to use are "free" (as in freedom) but are not equally licensed. Currently, we have only GPL data. But we should add Creative Commons data, which is free data. But so, what is the license of a package which include data under GPL and data under Creatives Commons? This would be exactly the same problem if we want to mix GPL data and BSD data.

In fact for the program package, the case is simple => GPL

For the data package, the licencing is to be per file, and the global
availability of this package should be limited by the most restrictive
licence.

Exemple : wikipedia
each file has it's own licence (creative commons most of time)

I would suggest for wormux-data a license like this one :
<<
 This package is under GPL bla bla bla
 For file using a different licencing, they come with a file.licence
 for specific licencing details.
>>
Exemple 2:
lovely-gnu.gif
lovely-gnu.gif.licence.txt
- author : gnuman
- this file is under CC licence :
  http://creativecommons.org/licenses/by-nd/2.0/fr/

As most files files under creative commons are freely redistributable,
the sharing of wormux-data will not be a problem.
The files which are not freely redistributables should obviously be
avoided.

Hope this can help  a bit.
