Good question. Thinh will give a more authoritative answer, but my answer is that CC0 is not a license - it's a waiver. Or rather, it's primarily a waiver, and only acts as a license when it has to, to cover situations where rights cannot be waived. If the material is not protected by copyright in your jurisdiction then you would use CC0 to reassure potential consumers, as well as to license it in jurisdictions where a waiver would not have legal standing.

Hi Jonathan (Nice to meet you at tdwg!)
I just posted to Thinh's blog entry this comment:
'Where talking about “facts, ideas, and concepts that are not copyrightable by themselves.” this blog entry seems to contradict the CC0 commentary about http://creativecommons.org/choose/zero which I understand to mean that, like all CC licenses, CC0 can only apply to copyrightable material. How is this reconciled with advocacy of application of CC0 to something that is not copyrightable?'

Sorry for the spam, but the subjects of data copyright, data licensing, and public domain came up repeatedly in conversations I had at the TDWG conference. I know this isn't really a technical issue, but tdwg-tag is the only TDWG list I'm on (so far). I'm hoping some of you will circulate the following pointer to your colleagues working on data policy. The article explains some of the issues around copyright and licensing as they pertain to data and gives the current Creative Commons position.
