The general tag for a source of drinkable water is amenity=drinking_water. But in some cases you will want to subtag an existing OSM-object (like an amenity=fountain) with the info that the water is drinkable.
Apparently our free tagging schema has led to 2 alternative keys for this: drinkable=yes/no can be found here: http://wiki.openstreetmap.org/wiki/Tag:amenity%3Dfountain drinking_water=yes/no is defined here: http://wiki.openstreetmap.org/wiki/Key:drinking_water The first is around 5 times more in use than the second. How shall we proceed in order to unify the two? cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
