Are the untagged ways here such as way/318349871 perhaps buildings of some sort?

If it's not "Nursing Home", what's the actual name of this nursing home?

What's the name of the nursing home way/317369968 ? Currently it's just called "Nursing Home" - the name should really be the actual name, with a main tag (e.g. amenity=nursing_home or something else) saying what it is.
