[OSM-talk] Historical Data in OSM database

[Peter Wendorff]

The problem is, and therefore it's not possible to get a good solution 
without changing the database layout: history information apply to 
attributes, not to objects, but tags only apply to to objects as a whole.

That's also a problem at some other issues discussed repeatingly, e.g. 
different opening_hours of two poi tagged on a shared node (e.g. one as 
amenity, one as shop).
