What would you say is the maximum number of ways/addresses for one street? >> After rereading >> http://wiki.openstreetmap.org/wiki/Relations/Relations_are_not_Categories >> I'm going to conclude that the proper place to put address information >> is in the building data, not in the street data, and that >> associatedStreet should therefore be deprecated. > > And if you read more on the wiki, you will discover that the Karlsruhe > schema is allowing both. I've read that. And what I'm saying is that it should only allow one. "Grouping relations really only make sense if the grouping is neither geographical (as discussed above) nor exclusive (like the HSBC example - the cash machine is unlikely to be operated by two different institutions at the same time). " The associatedStreet relation is exclusive. There is only one associated street for any address. The street relation, on the other hand, is not exclusive. There are ways (e.g. in intersections) which are part of multiple streets. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
