Modeling the White House in OWL

This evening it was time to re-visit the White House and re-factor it into it’s own OWL Dataset. I thought it would be of interest to use the White House as an example of a resource having multiple types.

Initially I had modeled the White House simply as the Presidential Residence but on further modeling I had to make it also an Office of Government. Using N3 Format, this is expressed in OWL as follows:

      a       gov:PresidentialResidence , gov:Office ;
      rdfs:label "White House"^^xsd:string ;
      dc:description "The White House is the official residence of the President of the United States, recognized worldwide as a symbol of the prestige of the presidency. Built between 1792 and 1800, the sprawling 132-room mansion has been used as a home by every President since John Adams."^^xsd:string ;
      gc:url  ""^^xsd:anyURI ;
      gov:commision usgov:WH-CNMR , usgov:WH-CPS ;
      gov:council usgov:WH-CEQ , usgov:WH-CEA ;
      gov:reportsTo usgov:US-Government ;
      gov:suborganization usgov:WH-FBCIO , usgov:WH-ONAP , usgov:WH-CEQ , usgov:WH-DPC ,
                                       usgov:WH-OA , usgov:WH-NSC , usgov:WH-CNMR , usgov:WH-NEC ,
                                       usgov:WH-CEA , usgov:WH-CPS ;
      =       <>


  1. Multiple types are expressed in N3 as a comma separated list of classes;
  2. Sub-organizations of a government body are named using a hyphenated phrase, For example: ‘WH-ONAP’;
  3. Where known, sub-organizations are specialized as ‘councils’ and ‘commissions’;
  4. a dbpedia link has been provided with an ‘owl:sameAs’ construct expressed in N3 as an “=” statement.
