Relationships
|
|
|
|
| Instances | entity | The universal class of individuals. This is the root node of the ontology. |
| | geographic area | A 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. |
| | object | Corresponds 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. |
| | physical | An entity that has a location in space-time. Note that locations are themselves understood to have a location in space-time. |
| | region | A 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. |
