Historic -- Explorations of an OpenStreetMap Approach to Historic Mapping
About Historic	English (USA)
This may now be the moment for OpenHistoricalMap. There's a critical mass of interest in exploring open collaboration of historic geodata. It makes a good deal of sense to approach this from the experience of OpenStreetMap. An open database and API, & free tagging with community discussion is a proven model for collaboration among a diverse set of uses. The software ecosystem offers much to build off: the API, renderer, editors, gazateer... Question for anyone who's looked at this closely is how tightly linked into OSM.org should this be. As is, you can easily specify time delimited tags (start_date=*, end_date=*), but the OSM tool chain does not have in-built awareness for them. For an example of the problem, here's the situation for multiple years of Burning Man (http://osm.org/go/Tc4Ki1bp-). Should OSM.org itself become time-aware, or rather, should OSM.org continue to represent only the "present moment"? No matter the answer, there's one good and feasible approach here to the broader question, and in any case, OHM will benefit.
