If anyone can add descriptive attributes of present features on present-in-osm objects, they shouldn't be deleted. A tag saying "this was a railway" is not historical (i.e. "gone"), but part of the life story of that feature. Affixing the data to relevant current objects is more precise than storing it separately in "some other database", when the posterity can't tell if those two databases refer to, say, in this example, different bridges that were in the same spot, different bridges close to each other but the location data wasn't accurate enough to indicate that they weren't the same bridge, or that the bridge was in fact the same bridge all along. An original cycleway bridge most likely looks a whole lot different from a railway bridge converted to host a cycleway, or any other less heavy stuff. Even if it wasn't, the mapper who sees the change or who's investigation reveals that the bridge is in fact the same that used to host the railway, has done a worthwile and original contribution. Tags are cheap. -- alv _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
