Major advantage is the structure. It is easy to have more many keys than kind of stuff under only a handful major keys. Especially amenity=* is still crowded. * it would be possible to have a default icon for education which is not possible with the mix under amenity * it makes it easier to document and design presets as we do not have to create a structure there as we already have defined one with the major tag. You are right that training is too generic but there is no difference in search if you either search for "amenity=*" or "education=*". cu fly _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
