Missing repository license #34

Closed stef4k closed 3 years ago

stef4k commented 3 years ago

There is no license file in this repository. I could create one if you could specify the license type.

Ah nice catch. I assume we should add the same BSD-3 license used by NetworkX. Since this is mostly pedagogical material though, maybe there's a reason to use different licenses for text/data/code? I'm not familiar enough with the finer points to have an opinion... @stefanv do you have any thoughts on this?

Here's what we have in the scikit-image tutorials repo:

All materials in this repository are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication (see LICENSE.txt).

However, we ask that you actively acknowledge and give attribution to this repo and to the authors if you reproduce them or create any derivative works. Specifically:

Keep the CC0 Public Domain Dedication intact when reusing large portions of the material (such as an entire lecture), so that others may benefit from the same license you did.

Do not represent yourself as the author of re-used material.

For more information on these guidelines, which are sometimes known as CC0 (+BY), see this blog post by Dan Cohen.

Too much text, and most of it can be cut, but: I think it's worth giving a clear indication that you are fine with users re-using the code without worrying about a license when it comes to tutorials and data.

Recently, in a conversation on the NumFOCUS projects list, it became clear that CC0 is not all that simple from a legal perspective. But, I think the intent behind it is clear: we don't care about how you use this stuff, and we certainly won't follow up on it.

Alright then, I will create a new LICENSE.txt file of the CC0 1.0 Universal, if that is okay.
