++Philosurfical: has-dimension slot was originally of thing, but it makes more sense here. We also have omitted the properties: P49 has former or current keeper, P51 has former or current owner, P58 has section definition, P59 has section. P53 has former or current location has been renamed to has-location. Has-current-keeper and owner moved down to man-made-object
