Nice analysis :). But just because this may be "all you care about", it doesn't mean it's an appropriate set of categories to use for tagging. 1) You gotta tag with verifiable tags. "Wide=yes", "smooth=yes", "gentle=yes", "bumps_and_kerbs_and_stuff=yes", etc., are not verifiable. 2) As I've said before, you gotta tag explicitly. Look at those categories - what are the factors involved in categorisation?: a) width b) surface c) corners d) presence of barriers e) the law Funnily enough, all of this stuff can already be tagged explictly and verifiably (see width=*, surface=*, barrier=*, etc.). Sure, you might be able to save a couple of KB's in the database by using your conglomerated, fuzzy categorisation scheme, but I think you'll find it won't solve the current problem. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
