I think it's even impossible to support all OSM tags on a specific map. When rendering a map or converting the data into a special format (e.g. Garmin devices) you always have lot of constraints. For example Garmins don't support an unlimited number of way types. So you have to map OSM tags to device tags, which is not always a lossless process. In addition it's often not even desirable to show everything - many maps have a special purpose and should only show the things relevant for that purpose. I think that map renderers and map makers already do their best to support as many useful (for their map!) tags as possible and most mappers do their best to map according to the wiki definition because they want their work to appear on the maps. Remember, the goal of OSM is a FREE map, not one with a lot of rules and restrictions. There are enough restricted maps out there. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
