| Instances | AtmosphericRegion | AtmosphericRegion is the class of all subregions of EarthsAtmosphere. |
| | substance compos�e | The Class of Substances that contain two or more elements (ElementalSubstances) in definite proportion by weight. The composition of a pure compound will be invariant, regardless of the method of preparation. Compounds are composed of more than one kind of atom (element). The term molecule is often used for the smallest unit of a compound that still retains all of the properties of the compound. Examples: Table salt (sodium chloride, NaCl), sugar (sucrose, C_{12}H_{22}O_{11}), and water (H_2O). |
| | entit� | The universal class of individuals. This is the root node of the ontology. |
| | objet | 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. |
| | physique | An entity that has a location in space-time. Note that locations are themselves understood to have a location in space-time. |
| | substance pure | The Class of Substances with constant composition. A PureSubstance can be either an element (ElementalSubstance) or a compound of elements (CompoundSubstance). Examples: Table salt (sodium chloride, NaCl), sugar (sucrose, C_{12}H_{22}O_{11}), water (H_2O), iron (Fe), copper (Cu), and oxygen (O_2). |
| | r�gion | 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. |
| | objet en une partie | A SelfConnectedObject is any Object that does not consist of two or more disconnected parts. |
| | SpaceRegion | The class of all Regions which are not GeographicAreas. |
| | substance | An Object in which every part is similar to every other in every relevant respect. More precisely, something is a Substance when it has only arbitrary pieces as parts - any parts have properties which are similar to those of the whole. Note that a Substance may nonetheless have physical properties that vary. For example, the temperature, chemical constitution, density, etc. may change from one part to another. An example would be a body of water. |
