I'm not sure what your “why” specifically refers to. I'll assume it's entirely covered by your following paragraph. > I can't imagine when the debian/copyright file would ever be useful > in that respect.

The point is that, since we can predict the need for this information, we have the choice of assuming the information is there when we distribute and never looking for it until the need arises in the face of such a threat, or looking for it in advance of distribution and hence in advance of exposure to that threat. I think it's clear that the latter option is preferable. On that basis, it would be foolish having *already* checked carefully that the copyright status is accurately known to then discard that information rather than recording it in a single documented location for others to verify. The only alternatives that seems to be on offer are either not checking the copyright information is accurate before distributing, or not recording what we learn in that check for later verification that the check was done at all. I argue that both of those are inferior to doing the check before distributing, and recording the result of that check in a single documented location. > > If ignorance of the copyright status of a work were a valid > > defense, that would certainly obviate the burden for a distributor > > to actively maintain accurate copyright status knowledge in the > > works they distribute.

Yes. That only leads to the ludicrous, but entirely real, situation that we are in: it is incumbent on any distributor of a work to establish that they have license to do what they're doing from the copyright holders, which necessarily means knowing who *are* the copyright holders in the work. > What matters is knowledge of the license the work is released under. Which necessitates knowledge of who is empowered to grant that license: i.e. the full set of copyright holders in the work. Collecting copyright notices isn't a requirement under copyright law: works that are copyright-restricted continue to be so with or without the notice. But unless we have the information typically contained in such notices, we are operating completely in the dark as to who is empowered to restrict distribution or grant it. -- \ “It is well to remember that the entire universe, with one | `\ trifling exception, is composed of others.” —John Andrew Holmes | _o__) | Ben Finney -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
