The new Contributor Terms contain the equivalent of a joint copyright assignment to the OSMF. That makes this recent article by Michael Meeks on copyright assignment in free software very relevant: http://www.gnome.org/~michael/blog/copyright-assignment.html
Of course, not all of the pros and cons he raises are relevant to data rather than software. But the following sentence struck me: "It appears (to me) that choosing a license that can be upgraded and bug-fixed in-flight by a responsible steward or proxy substantially removes the requirement of assignment for re-licensing." I would recommend reading the whole article.
