Identifying is simple, but what to do with those elements is much more complicated. Sorry, but foo=dismantled and end_date=* have a lot of issues, they're not good enough.

So far we've avoided the problem by sticking to the "we map the present" principle (meaning stuff that no longer exists gets deleted). Before we can change that stance, we need a credible solution to the "map the past" usecase.
