Publishing data under Creative Commons license: CC0 or CC-BY? I am submitting a data article to an open access journal, with the data available in a repository (Open Science Framework). I need to add a license to the data repository. It seems from some internet research that the CC0 would be the correct option for a data set, but I have a hard time finding the difference between CC0 and CC-BY licenses.
So I have 2 questions: first, would CC0 be appropriate, and secondly, what is the actual difference?
CC-0 is considered the best choice for scientific progress because it lowers barriers to reuse.

Dryad has a nice and compelling explanation of why they require CC-0 in their FAQ https://datadryad.org/pages/faq#info-cc0

Here is one excerpt:


  CC0 does not exempt those who reuse the data from following community norms for scholarly communication, in particular from citation of the original data authors. On the contrary, by removing unenforceable legal barriers, CC0 facilitates the discovery, reuse, and citation of that data.
