[Historic] Temporal Tagging

[Robert Warren]

No doubt that detail of tracking would appeal to some of the more hardcore historians. What you suggest also applies to buildings / amenities that have been repurposed to museums for examples. 

For movement, the only thing that I can think of is to encode time into sets of node/ways to account for movement and have the renderer deal with the problem. I'm not sure how well this will scale through.


Incidentally, is HOSM going to use the same database as OSM like OpenSeaMap does or is it going to be a separate store altogether?
