[Wikisource-l] CC version 4.0 material in Wikisource

[KuboF Hromoslav]

Hi there!

In the Esperanto Wikisource we have get a licensing problem. Can you help
us, please?

In the Esperanto User Group we have successfully advocated at the World
Esperanto Association to free their press communications, so we can put
them into Esperanto Wikisource. I have putted the first one as a test [1]
but was alerted about possible license incompatibility.

The material is under CC BY 4.0 but Wikisource is using CC BY-SA 3.0. (so
the problem is the version number) The argument is, that CC licenses are
"forward compatible" but not "retro compatible". So it is OK to put CC BY
3.0 material into CC BY 4.0 repository, but not the opposite.
In the meantime I have found, that another Wikisources are collecting
materials under CC BY 4.0, like
https://en.wikisource.org/wiki/Category:CC_attribution_4.0

If it is OK to use CC BY 4.0 material in Wikisource, can you make some
short legal reasoning so I can inform the Esperanto community? (and if it
is not OK, we should think about the content already in use, like the
linked one upper)

Note that Wikipedia uses many images under a variety of licenses, including
CC BY 4.0 and fair use. An entire Wikipedia is not covered under any single
license. Likewise, an entire Wikisource is not covered under a single
license;
https://en.wikisource.org/wiki/The_Grant_Shapps_Affair_Is_a_Testament_to_Wikipedia%27s_Integrity_and_Transparency
is covered under the CC-BY-4.0 independently of any license the rest of
Wikisource is covered by. It's mere aggregation, not making a derivative
work.

At the bottom of each page on wikisource is written:

Content is available under CC BY-SA 3.0 unless otherwise noted.

So basically, works under a different free license should be simply come with a statement in the page that reproduce them.

So for the exposed goal of archiving communications, there is really no big deal. Problem might only arise if we try to mix different pages up. If CC is indeed forward compatible, then mixing 3.0 and 4.0 licensed works should make the result only available under 4.0. More subtle, but still not a blocker.
