This has been repeated so many times, but in reality large parts of the ontology has been "official" for quite a while now, haven't it? The largest problem lies in tags that aren't used much. The meaning of tags are not just decided by "key=value", but also who tagged it and when the user tagged it. Since every user will interpret tags differently, so you can never be sure exactly what was meant. E.g. What exactly is "landuse=allotments"? Can you walk on highway=cycleway? I think Richards idea is one of the better ones if you want to continue the anarchistic tradition of OSM, every user has their view: http://www.mail-archive.com/[email protected]/msg12716.html _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
