I was just proposing a compromise. I don't care what the tags are so long as they are well-defined. highway=qwijibo (or highway=invisible_path) is fine with me. The wiki right now says that highway=path is to be used for paths, which is incredibly unhelpful. There are also some examples, which suggest to me that a "path", as used by OSM, means essentially "any highway (place open to the public where people travel) which doesn't fall under another highway=* tag". If I thought the wiki was a productive work environment, I'd try to add that more specific definition there. But I don't. If that isn't the definition, then I propose "highway=highway", to have that definition. Personally, I don't see much sense distinguishing between different types of "highway"s except in areas where there is a formal legal designation. Number of lanes should be represented by lanes=*. Maximum speed should be represented by maxspeed=*. Surfaces can be described with surface=*. Access is determined by access=*. Importance can then be determined, objectively, during a preprocessing stage which factors in all these conditions along with the physical connections. It should then be the job of computers to combine all those elements together and decide what colors to paint things. I don't see that happening, so I'll just make my best guess as to which highway=* tag to use, and not particularly worry about it (except when someone tells me that I can't use *any* of the highway=* tags for something which ought to be in the routing network). _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
