Open source was the wrong term (though that would be fine).
I meant community-sourced. Some kind of community where local "experts" or history enthusiasts could contribute info.
AKA - invite a local or regional historical society to contribute data for their region, with the benefit that they could then easily generate a regional tour map/route/recommendation.
Aha.. yeah, that makes a lot of sense. I think that's probably the best way to catch the more niche and special interest history.
