Has Building Type

Connects a building to the concept naming the kind of building it is, such as a house, palace, castle, church, mosque, museum, bridge or skyscraper. The inverse reading, Building Type Of, names the same link from the building type toward each building grouped under it. This relation gives the building type already recorded as an enum fact on each building a durable entity identity; it does not replace that enum fact, which keeps classifying every building exactly as before, and a compound label such as Stadium, Arena or Amphitheater, or Cinema or Theatre, is linked to each of its named components.
