What's a "derivative work"?

Or more to the point, how much do you have to have altered
a work before you are entitled to upgrade the license?  How
is this decision made?

Perhaps the entire wiki is a "derivative work"?

More likely, it is a "combined work".

Except of course that you may not be allowed to publish the
wiki if it is considered a "combined work" and some of the
contributions are CC-By-SA-1.0!

Cheers,
Terry
