[OSM-talk] Tagging POI's - Nodes vs. areas

`amenity=hospital` is what makes it a proper hospital. You can create a node where the hospital is, or an area around the property of the hospital. Drawing either a node or an area is ok, but drawing areas is preferred if you have time for it.
If the hospital is just one building, you can add `building=yes` or `building=hospital` to the amenity. If the hospital is a campus of several buildings, you can draw each building as well. `building=*` (anything) should make it render like a building/structure. The actual value of the building tag is not really used often (it’s considered a description of what the building looks like, not what it is), so most buildings are just tagged as `building=yes` unless they are really special somehow.

One way to tag the polygon would be "building = hospital." Another way would be "amenity = hospital." Another way would be to simply tag the building as "building = yes" and then place a node inside the building polygon and tag the node as "amenity = hospital." I'm thinking in terms of how the hospital will show up in the various renderers. Do most renderers require the "amenity" tag in order to display a hospital symbol at that location? (In other words, what happens if I just use the "building = hospital" tag on the polygon and no amenity tag?) And what about the hospital name? Do I include it with the building polygon or the node? Or both? This is very confusing. It seems there is a certain amount of overlap when it comes to the application of building, amenity, and shop tags.
