Location Information
  - AirportCodes.daml doesn't include latitude/longitude location information
  
- I add those properties to Terry's objects in
      locations.n3
  
- geofile
      is a DAML source of location information
    
      - incomplete
      
- uses 4-character rather than 3-character airport (ICAO) codes
      
- represents latitude and longitude in degrees/minutes/seconds/direction rather than signed decimal degrees
      
- might be used with future DAML inference
          rules and/or ontology translation facilities
      
- locations.n3
          uses
          daml:equivalentToto identify corresponding geofile objects
