One meaning per tag is essential. If a German cycleway is *different* in some important way to a UK (or whatever) cycleway, it should ultimately be tagged *differently*. I find this obvious. The details of how they should be tagged are of secondary importance. To answer your question specifically, I don't have so much of a problem with highway=fahrradweg, though I doubt that's the best way to do it. If highway=fahrradweg at least has the same meaning in all usages, it would be an improvement! _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
