Well, recognising that it has a temporal dimension still doesn't let you

I think not, and that is why I think the temporal part of ttdb: doesn't  
answer sufficient a need.

We could of course introduce properties

	wasPrimaryTopicOf
	willBePrimaryTopicOf
	shouldHaveBeenPrimaryTopicOf

just to be on the safe side.
