it doesn't change the good point Ulf made: a potential data consumer would have to know all school types for a pleasant results. Currently most schools are tagged with amenity=school and maybe a name. This is sufficient for many maps. If we now start to put all kind of special interest schools, sports facilities and other in this category, it will get useless. Renderers would have to know all local types of general schools that will get entered in the subtag school (because it will not remain general and because it is a good idea to tag school=fr:lycee, de:Gymnasium, it:liceo, highschool, etc.). Or they will only evaluate one tag (amenity=school) because they do this for years, and they will start to display rubbish. I'm generally in favour of subtagging, where it is adequat. I just don't see the benefit here and worse, I feel it would harm. In the case of schools I think there are already enough different types of general-education schools to differentiate. If you make a map of schools you will in most cases don't want the boxing schools in. Another hint might be to see how others handle this. If you look at wikipedia: http://en.wikipedia.org/wiki/School http://en.wikipedia.org/wiki/List_of_schools_by_country there is not the faintest hint to other than general education schools. No word about driving schools or dancing schools. They are very different. Really. Btw: the OSM Wiki refers to Wikipedia's definition of school. cheers, Martin _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
