      A natural-language representation for a concept that is both human 
      readable and readable by the Cyc inference engine. These terms are not 
      guaranteed to refer to the same concept across time but are guaranteed to
      be consistent within a particular OWL export. Use 'cycAnnot:externalID'
      for unambiguously referring to a concept across OWL exports or across Cyc
      inference engines.

It is characterized by plain straight lines and planes, and only simple geometric ornament (as opposed to neoclassic or gothic), if any. &apos;Modernity&apos; through severe simplicity of geometric appearance was sought.  Almost every commercial and government building in the mid to late 20th Century was in this style.
