Relationships      
InstancesentityThe universal class of individuals. This is the root node of the ontology.
 geographic areaA 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.
 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.
 self connected objectA SelfConnectedObject is any Object that does not consist of two or more disconnected parts.
 transitwayTransitway is the broadest class of regions which may be passed through as a path in instances of Translocation. Transitway includes land, air, and sea regions, and it includes both natural and artificial transitways.
 water areaA body which is made up predominantly of water, e.g. rivers, lakes, oceans, etc.
