Well, this discussion has been held a lot of times in the past. It's completely impossible to mold the entire world into a set of tag rules without exceptions in any country at all. It already starts with the definition of each different category of vehicle, so we couldn't even make a tag set which is valid for the entire world if we were to tag every vehicle type explicitely (think roads that have motorcar=yes, goods=yes, bicycle=yes, motorcycle=yes, foot=yes, horse=yes etc). We in Belgium have two types of mopeds, in other countries they have mofa and moped, other countries have a single type of moped, and then the rules start to change what it means exactly if you tag a road with moped=no. So yes, we have to have country defined rules about access tags. And one of them is that access=destination will always allow pedestrians, cyclists and horse riders in Belgium. Another one for example is that a motorroad=yes will disallow pedestrians, cyclists, mopeds, horse riders and other animal drivers without having to add all these explicitely. I know it's not an elegant solution, and that it does put a big burden on all data users to interpret what access tags mean in every country, but I always had this "dream" already quite some time ago that one day some kind of a library would be built that would take the tags on a road, and then you can ask if a certain vehicle is allowed or not for that given country. A place where all these local country rules would be defined. But I guess that's beyond this discussion :-) Greetings Ben _______________________________________________ Talk-be mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-be
