[OHM] tagging for historic race tracks / NEH

[Jeff Meyer]

Rob & the list -

Is there a metadata standard for historical geodata we should be
encouraging / eventually enforcing for contributions?

Even if there's not a perfect fit, it would be interesting to see the
differences between that effort & what the OHM/OSM key:value structures can
support easily.

Enforcing start_date at the API level might be a start in this area?
