Hi Christian - Right now, the current OSM infrastructure is very good for showing what is here today.
I believe one of the goals of Historical OSM is to show what the world looked like at any time in the past. Some of the problems with using the current database are: how to remove objects that didn't exist 100 years ago, how to draw objects that did exist 100 years ago, but are now gone & covered up by other roads or buildings? So, the goal of setting up a parallel OSM Stack (not just the Rails Port) will be to set up an environment where we could edit maps for the same place for multiple times and also serve tiles for multiple times. For example, to show what cities and roads looked like in Burgundy after the Treaty of Verdun or what the road system across France looked like in the 1800s, after trains, but before cars, etc. I think the place to start, though, is to start working on the workflow of using old maps for tracing information and picking some sample projects at various locations around the world. Then, after learning by doing, we could see what tools needed to be developed most urgently. Does that help?
