This is a somewhat complicated situation, and I have trouble finding a Creative Commons license that is appropriate.
Here is what I want the license to do:
- Others should be able to redistribute my exact artwork, but only non-commercially.
- However, they can do whatever they want commercially with the derivative works they produce, including allowing others to use their work commercially.
- It should be allowed to make derivative works from the derivative works.
When I try to find a CC licence that is suitable for this, I end up in a contradiction. Here is the logic:
- To comply with my condition number 1., I have to include [non-commercial].
- Also by condition number 1., I can not include [no-derivative].
- If I include [share-alike], they must use the same license, including the [non-commercial]. That contradicts my condition number 2. Dead end.
- Then, I can not include [share-alike], but then they are free to apply [no-derivative] to their derivative work, contradicting my condition number 3. Dead end as well.
My conditions are reasonable (perhaps a little too restrictive, but that is another discussion), so it should be possible to cover them with a licence. Writing your own license is not recommended, so what should I do in this situation?
