And English usage is rather fluid. This leads to anomalies. Any enclosed space built by man that a person can occupy is, in one sense, a building. Anything built by man is, by definition, man made. And, since man is a part of nature, anything built by man is also natural (if a beaver dam is natural artefact then so is the Hoover Dam). Thankfully, OSM tags aren't cladistic, or we'd have natural=skyscraper. That said, most people would classify houses, garages and even sheds as buildings but exclude bus shelters. I'd also expect a bus shelter to have, at a minimum, a roof and at least one wall. I don't think we need to tag it with covered or roof because if it doesn't have a roof/canopy it's not a shelter As in you cannot shelter from the rain unless it has a roof. Note also that at one point in time (around 6 months ago) some page in the wiki I stumbled across said that covered=yes in combination with a bus platform meant that the platform was underground or something like that. Which had me hastily remove the covered=yes I'd put on bus shelters because a few months prior to that something in the wiki implied it was as necessary as tagging a bench if there was one. It would be nice if we could sort this out. :) -- Paul
