With current semantics it is not possible to decide where to go with an ID if an object gets changed. Many objects have tags like building=yes, amenity=xy on them, and you can't even tell from the data whether "name" is referring to the building or to the amenity. How would you know whether the ID was used for the building or for the service inside the building? cheers, Martin _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
