[Data-modeling] Current heads of state

[Jeff Prucher]

There's a discussion thread started by user joguinn on the /location type
that I'd like to get more input on. The original thread is here: 
<http://www.freebase.com/discuss/threads/location#/guid/9202a8c04000641f8000
0000086ea1f8>  (it's the last few comments in the thread "City Parks/Golf
Courses").

The request is to include a property for "current head of state" on the type
Country. This would be a partial denormalization of the Governing Officials
property on the Governmental Jurisdiction type, but consistent with a
pattern that we've seen several times lately.  It would also have some
additional semantic value, since we have no way in the current model to
assert that any particular office represents the head of state.  The reason
I'm bringing it up here is that I can imagine this snowballing into a slew
of "Current X" properties on various location types ("Current Mayor",
"Current Legislators", "Current Insurance Commissioner", etc.) and I'd like
to hear what people think about either the proposed property as it stands,
or the potential proliferation of similar properties.

Thanks, 
Jeff
