License for Throwable-SugarFactory

[Emmanuel Seyman]

Hello, all.

I'm about to package the Perl distribution Throwable-SugarFactory[0]
which one of my packages now depends on.

The "Copyright and License" section of the page[0] reads:
 "Christian Walde has dedicated the work to the Commons by waiving all
 of his or her rights to the work worldwide under copyright law and all
 related or neighboring legal rights he or she had in the work, to the
 extent allowable by law.

Works under CC0 do not require attribution. When citing the work, you
 should not imply endorsement by the author."

Can I package this ? How do I express this in Fedora conventions?

Regards,
Emmanuel

This sounds like a public domain dedication. Fedora already recognizes the
following text as the dedication:

To the extent possible under law, the author(s) have dedicated all
    copyright and related and neighboring rights to this software to the
    public domain worldwide. This software is distributed without any
    warranty.

Throwable-SugarFactory is similar.

As far as I know CC0 does not require an attribution: I was unable to find
such requirement in CC0 and CC0 FAQ confirms it
https://wiki.creativecommons.org/wiki/CC0_FAQ#Does_CC0_require_others_who_use_my_work_to_give_me_attribution.3F.

Therefore I think we can ignore this section.

I guess adding the text to public-domain-text.txt into
https://gitlab.com/fedora/legal/fedora-license-data.git and using
LicenseRef-Fedora-Public-Domain identifier in the License tag.

I see this text as merely some verbiage they've added to the API docs
as a human targetted summarization of the licensing. IOW, I would
ignore this specific text.

The actual license is clearly stated in their top level LICENSE file,
which repeats this summarization, but then provides the full CC0 1.0
license text. IOW it is clear that the license is CC0 IMHO:

https://metacpan.org/release/MITHALDU/Throwable-SugarFactory-0.213360/source...

The problem is that CC0 has been forbidden by Fedora for newly added
packages if applied to code. It is only permitted for content. So it
would look like this package cannot be added to Fedora today.

With regards,
Daniel
