[OSM-talk] Temporary Items, overlays, changes

I think that "temporary" and "historical" prefixes are the best answer
to this, possibly with a relation for roads that are different due to
the same event, project, etc. Tag things with what they are generally
at the current day, and add exceptions as needed. I would envision an
example like:

highway = unclassified
name = Main Street
temporary:highway = pedestrian
temporary:start_date = 2009-01-16
temporary:end_date = 2009-01-20
notes = closed to cars during the music festival

I don't know how to handle multiple temporary items. Perhaps
"temporary1", "temporary2"...
