Code voorbeeld met Triple store

Onderstaande code genereert een triple store met nodes, welke predicaten bevatten waaronder:

  • Registered At
  • Parent Of
  • Married To

In de store worden personen en instanties zoals BRP opgeslagen. De predicaten zijn voorzien van temporale aspecten (ActualDateTime) vanuit de Discrete Event Simulatie. Door de simulatie af spelen ontstaat er over tijd zo bijvoorbeeld een gezinssituatie.
