[OSM-legal-talk] Questions about CTs 1.2.4

Hi all,

After looking at the new CTs, I'm still a bit confused about whether I can agree or not and what a few things actually mean. I was wondering if someone could enlighten me.

From clause 1 "If you contribute Contents, You are indicating that, as far as You know, You have the right to authorize OSMF to use and distribute those Contents under our current licence terms"

To me, that says I can upload any data as long as it's compatible with whatever license we are using at the time. That is, I can agree to the CTs and then still upload ODbL incompatible data because our current licence is CC-BY-SA.

* Is that a correct reading?
* If so, how do we know what data must be removed in a switch to ODbL?

Clause 2 is a grant for certain rights. From previous discussion here, can I assume that I can agree if I'm not the copyright holder, and that I only grant the rights I can under the licence I received the data under?

If that is correct, then OSMF may not be able to re-license under clause 3. For example I got data that could be re-licensed under CC-BY-SA and ODbL so I could upload it, it's not necessarily going to be able to be re-licensed under any arbitrary future licence. How do we indicate that?

If my earlier reading of clause 1 was wrong, and I can't agree to the CTs and upload CC-BY-SA data - why? If it's related to clause 3, would that same reason stop people uploading ODbL-only data in future since it can't be re-licensed to CC-BY-SA (which is listed)?
