Was man schon immer mal wissen und übersichtlich erklärt haben wollte:
I used part of a Creative Commons-licensed work, which Creative Commons license can I relicense my work under? (die Frage ist aus der Creative Commons FAQ, das schicke Chart von CC Taiwan).
The answer is it depends. There are different types of Creative Commons licences. Hopefully your source has a Creative Commons Attribute 2.5 licence. Then you are free to share or remix the original work. Unfortunately there is proliferation of Creative Commons licences which . Thus Creative Commons licence is getting as complex as original copyright rules and makes it somehow useless for typical users without a degree in international copyright. Yet an other web initiative taken over by the lawyers.
