Relationships      
InstancesEntityThe universal class of individuals. This is the root node of the ontology.
 GeographicAreaA geographic location, generally having definite boundaries. Note that this differs from its immediate superclass Region in that a GeographicArea is a three-dimensional Region of the earth. Accordingly, all astronomical objects other than earth and all one-dimensional and two-dimensional Regions are not classed under GeographicArea.
 HemisphereHemisphere is the class of GeographicAreas that are halves of the Earth, as traditionally divided into the Northern and Southern Hemispheres along the equator and into the Eastern and Western Hemispheres along a north-south line running 20�W and 160�E.
 ObjectCorresponds roughly to the class of ordinary objects. Examples include normal physical objects, geographical regions, and locations of Processes, the complement of Objects in the Physical class. In a 4D ontology, an Object is something whose spatiotemporal extent is thought of as dividing into spatial parts roughly parallel to the time-axis.
 PhysicalAn entity that has a location in space-time. Note that locations are themselves understood to have a location in space-time.
 RegionA topographic location. Regions encompass surfaces of Objects, imaginary places, and GeographicAreas. Note that a Region is the only kind of Object which can be located at itself. Note too that Region is not a subclass of SelfConnectedObject, because some Regions, e.g. archipelagos, have parts which are not connected with one another.
