<p>Can you clarify whether you can you put a copy of a work in the
public domain while maintaining a license on another copy? Or is
it the work itself that is placed in the public domain, and any
ability to enforce copyright on any copies has been surrendered?
My understanding was that works are placed in the public domain
while copies are licensed, and that placing a work in the public
domain renounces any copyright claim you might have on any copies
regardless of what license they may have been previously released
under. You seem to be saying that a particular copy of a work can
be placed in the public domain while other copies remain under
copyright restrictions?<br></p></div></blockquote></span><div>I oversimplified. A work in the copyright sense is really an expression of the abstract work. Beethoven's Ninth Symphony is an abstraction existing in people's minds (originally only Beethoven's mind) and not in itself subject to copyright, whereas each draft of it that he wrote down, as well as each recorded performance of any draft, constitute different expressions ("fixations" in copyright jargon) of the abstract work. Likewise, multiple editions of a book are separate expressions. Each expression exists in one or more manifestations. For example, a specific recording of the symphony, which is an expression, can be manifested as a vinyl disk, a cassette, a CD, a digital version. The manifestations of a book might be as a hardback, a paperback, an e-book, or in a single-volume vs. a multi-volume version. And each manifestation typically exists in multiple copies.<br></div><div><br></div><div>Copyright status attaches to the expression: if a specific expression is in the public domain, then all manifestations and copies are too. . The 11th Britannica (an expression which manifests as a set of books and several websites) is in the public domain, whereas the 15th Britannica is not. Licenses can attach to an expression, a manifestation (you may have one license for a CD and a different one for digital audio), and exceptionally to a copy.</div><div><br></div><div>CC0 is both a public domain dedication and a license. If the dedication is effective, then it affects all the manifestations (on a website or a CD/DVD-ROM) and copies. If it is not, then the permissive license affects only the copies it is attached to.</div><span class="m_-7534304278307107866m_-73495555405733346gmail-"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex"><div bgcolor="#FFFFFF"><p></p>
<p>With regard to bundled exports, it would help me to look at a
concrete case. Say we have an export from MakeHuman that consists
of three files</p>
<p>1) A 3D mesh that was created starting with a 3D mesh that comes
with MakeHuman and transformed by the user using MakeHuman.</p>
<p>2) A meta-data file containing information about the character
and its appearance created by the user using MakeHuman</p>
<p>3) A texture in the form of an image file from the MakeHuman
collection of texture images.</p>
<p>Let's say the user chooses to take the CC0 option. What is the
copyright status of the three files? Are all three files now in
the public domain? Can the user, or a third party use the
individual files without being restricted by the AGPL license that
would apply if the CC0 option hadn't been taken? Or is it only
the particular combination of the three that is in the public
domain while the individual files are still under copyright? If
it is only the combination that is in the public domain, does it
revert to AGPL if you make any modifications?</p></div></blockquote></span><div>I can't answer this specifically. But in general, a work that combines public-domain material and copyrighted material is itself subject to copyright, provided the copyrighted material is used under license. Obviously, if the creator of the combined work and of the copyrighted material are the same, such a license isn't hard to obtain.</div><div><br></div><div>-- </div><div><span class="m_-7534304278307107866m_-73495555405733346gmail-"><div>John Cowan <a href="http://vrici.lojban.org/~cowan" target="_blank">http://vrici.lojban.org/~cowan</a><wbr> <a href="mailto:cowan@ccil.org" target="_blank">cowan@ccil.org</a></div></span><div>My confusion is rapidly waxing</div><div>For XML Schema's too taxing:</div><div>I'd use DTDs / If they had local trees --</div><div>I think I best switch to RELAX NG.</div></div><div><br></div></div><br></div></div>
