How about capturing some of the data in the FEATURECOD field? Here's the values present:
General Government Education Recreation Commercial Hotel/Motel Religious Community Center Medical Industrial Airport Cultural/Heritage (null) It seems most residential buildings are listed as General, but mapping at least "Commercial" to building=commercial and "Government" to building=public seems safe enough. I guess a couple of others would make sense too (like Community Center implying "amenity=community_centre"). The data also has several other metadata fields like height and roof type, but they appear to be poorly determined or sparsely populated.
