Worst case, if the group prefers a meaningful label, I'd prefer /annotation/ over /openannotation/. I suppose 'open' does not add much info in the context of a W3C namespace. Such a change would also tell something about the maturity and ambition of the initiative :-)

Well... this is again the # vs. / question.

Having

http://www.w3.org/ns/annotation/core#BLABLA
http://www.w3.org/ns/annotation/ext1#BLABLA

is of course no problem. Having '/' means a file per term, which means the maintenance costs become higher. Whether that is spread over several directories is of course not a real difference. It will be the number of terms that will count (in contrast to the number of extensions in the case of a '#' approach).

I appreciate you want to foresee the future but sometimes, pragmatics is good too, and in this case, it does not harm extensibility so I would indeed be in favor of dropping /core.
