I’m wondering about whether it might hurt to use the "no derivatives" clause when licensing a scientific article under a Creative Commons license. My impression is that nobody ever creates "derivative works" in academia, that would simply be considered as plagiarism.
A related question is the usefulness of the "share alike" clause. Note for instance that the arXiv proposes both CC BY and CC BY-SA. What is the difference? Are there any derivative works of an article that would not be plagiarism?
I’m only talking about an article, for instance a theorem and a proof in mathematics, not about any kind of computer code which one may want to reuse.
