Having talked to people who process the data for use with geocoding, addr:street is a lot more robust than associatedStreet relations and a lot easier to process. Auto-complete helps with name consistency. I think the reason is that addr:street can be broken each time the name of a road changes while associatedStreet can be broken each time someone edits the street or address for any reason. Although addresses aren't fixed in practice streets aren't often renamed and every way split has a good chance of breaking the relation. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
