In general terms, a CCL can be used for any copyright protected work (books, movies, etc). However, since the work released under a Creative Commons licence is governed by the applicable national copyright law, national legislation may pose restrictions to the context of the free distribution. Moreover, it is to be noticed that Creative Commons – a creator of CCL – does not recommend the use of Creative Commons licences for software.
Furthermore, Creative Commons licences are non-revocable. This means that once a piece of work has been made available under a CCL, this work, or its copies, may continue to be used only under that licence.
