Thanks, @tda!! That's a very kind and optimistic post. I think everyone in the OHM community is working with good intents to create a rich resource available for easy reuse and download. You hit the nail on the head about trying to combine various different geo/temporal efforts to provide greater context of world history. Our tagging system is like OSM's - very flexible - with all the strengths and weaknesses that offers. And, the tagging system has limitations that we're currently working through & around. One strength is that any object (node, way, relation in OSM-speak) can have multiple sources. e.g. source:1=url1, source:2=url2, etc. And, tagging areas as disupted=yes is pretty straightforward. bit.ly/disputedUSA We have yet to hit any sensitive areas of debate, but I imagine that will happen in the not too distant future. OHM's system is inherently vulnerable to vandalism, but the goal is to allow conflicting perspectives to coexist, as long as they are sourced. Wikipedia tags are supported & perhaps more importantly, Wikidata. Wikidata also supports OHM references.
