The universal class of individuals. This is the root node of the ontology.

collection | Collections have members like Classes, but, unlike Classes, they have a position in space_time and members can be added and subtracted without thereby changing the identity of the Collection. Some examples are toolkits, repeated actions, football teams, and flocks of sheep. |
| content bearing physical | Any Object or Process that expresses content. This covers Objects that contain a Proposition, such as a book, as well as ManualSignLanguage, which may similarly contain a Proposition. |
| financial asset | Any item of economic value owned by an individual or corporation, especially that which could be converted to cash. Examples are cash, securities, accounts receivable, inventory, office equipment, a house, a car, and other property. |
| 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 system | PhysicalSystem is the class of complex Physical things. A PhysicalSystem may have one or more corresponding abstract Graph representations. |
| process | The class of things that happen and have temporal parts or stages. Examples include extended events like a football match or a race, actions like Pursuing and Reading, and biological processes. The formal definition is: anything that occurs in time but is not an Object. Note that a Process may have participants 'inside' it which are Objects, such as the players in a football match. In a 4D ontology, a Process is something whose spatiotemporal extent is thought of as dividing into temporal stages roughly perpendicular to the time_axis. |
