As for CC0, as Ben explained, it is a license, and the simplest is to list the
copyright holders as for other licenses.


Hi,

thanks for the suggestion. (BTW, is the fact that CC0 is a licence 
rather than a dedication an accepted POW? I thought it was still an 
open question.)


Could the copyright-format page [1] be changed to state more explicitly 
that the Copyright field should list the names of the authors even in 
the case of public domain works (or works licensed via CC0)? I would 
like to file a bug report but I do not see which package I should use 
for that.

The conservative position, since the current copyright regime makes it
extremely difficult to divest a work of copyright, is to assume the work
remains under copyright restrictions even with the CC0 dedication.

Regardless, the DEP-5 standard treats CC0 as a “license”, so if you want
to conform to that standard, that's the place to put the information.

 Could the copyright-format page [1] be changed to state more

 authors even in the case of public domain works (or works licensed via
 CC0)?

I don't see that follows from what we've discussed. The document states
explicitly that in the case of a public domain work you *don't* need to
list copyright holders::

Fields
[…]

Copyright
[…]

If a work has no copyright holder (i.e., it is in the public
domain), that information should be recorded here.

You should specify the license as CC0, you should give the text of the
CC0 grant (the text which says the recipient has the rights described by
CC0) in the License field body.

If you've got documentation that the work has no copyright holder,
that's the documentary information to put in the “Copyright” field.

My understanding is that it's both, stuck together, in one convenient
document - to work around the jurisdictions where you can't relinquish
copyright, and the jurisdictions where it's unclear whether you can or not.

The tl;dr version of CC0 is if my jurisdiction lets me put this work in
the public domain, I'm doing that, and if not, you may copy/modify it
under this very broad permissive license. The quantum superposition
won't collapse unless it becomes relevant to a court case :-)

I'm sorry but I fear that my main message did not came across. I will 
try reformulating my question with a example.


We have the case of software foobar released by John Doe using the 
licence CC0. foobar is not in the public domain (John Doe is well 
alive) but something similar, given the use of CC0.


We want to package foobar. What should we write in debian/copyright?

Solution 1 (no names in the Copyright field:


Files: *
Copyright: Public domain (CC0)
License: CC0

License: CC0
 Creative Commons Legal Code
 [... rest of the CC0 text ...]


Solution 2 (names in the Copyright field):


Files: *
Copyright: Dedicated to the public domain (CC) by John Doe
License: CC0

License: CC0
 Creative Commons Legal Code
 [... rest of the CC0 text ...]


Or is there an even better third solution?

Bye,

Thank you.

Right. The Debian standard format for ‘debian/copyright’ treats CC0 as
a license, and has a keyword for that license.

 We want to package foobar. What should we write in debian/copyright?

If you have compelling written evidence that the work has no copyright
holder, put that exact wording in the Copyright field.

If, as I think will be much more likely, the work has copyright holders
anyway, list those in the Copyright field.

Hi,

the machine-readable specification is contained in the debian-policy package,
and there is already a bug opened on that matter.

Solution 2 is fine; Copyright: [year] John Doe would be enough as well.
