how this would get done is all part of the laboratory aspect of the
that exist, maps of current historical sites, are all reasonable things
existing OSM database. the idea here is that things that no longer exist
historically significant go in the history database and we use
openlayers to do
a mashup on top of a rendering of modern OSM. so you've distinguished by
two different databases, and the historical database can use tagging
be considered clutter in modern OSM.
i will look into where this can be hosted, and look into setting up a
for those interested in the project to communicate. i'd consider hosting
it on my
own hardware, but i think i'd like to increase the available disk space

So, the tagging would need to distinguish between the two statuses.
