OSM uses highway=milestone to mean a road marker in general, rather than a traditional milestone (which was a stone with distances in miles carved on it). The OSM milestone may not have a distance marked on it, but if the distance is given then it is assumed to be in kilometres unless a unit abbreviation follows. So "9" would be 9 kilometres but "9 mi" would be 9 miles. I have to say that I think using "milestone" to mean a road marker that isn't a stone and probably isn't marked in miles was an incredibly bad idea. But we're stuck with it. Even so, a default of kilometres for a thing called a milestone is sub-optimal. What I'm unclear on is if these addresses refer to an actual road marker, or an actual distance based upon interpolation between actual road markers. If you have a road marker at 8km and another road marker at 9km, would a house between the two have addr:milestone 8, 9 or 8.5? If the address is of an actual road marker then addr:milestone would be appropriate (given that we already misuse highway=milestone to mean kilometre markers); if it's a distance that doesn't correspond to an actual road marker then we need a better name. -- Paul
