That's an interesting idea. Note that if we want to maintain a "singly linked list" of the successions of one OSM feature by another (or a set of them) we can link either way: from new to old or old to new. This wouldn't really be a list, more like a graph because one feature can substitute many and many features can replace one. (Not that I want this feature, just wondering) Cheers _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
