Relationships

|
|
| Instances | Autonomous agent | Something or someone that can act on its own and produce changes in the world. |
| | 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. |
| | entity | The universal class of individuals. This is the root node of the ontology. |
| | group | A Collection of Agents, e.g. a flock of sheep, a herd of goats, or the local Boy Scout troop. |
| | international organization | InternationalOrganization is the class of Organizations whose activities have international scope and which typically have members who are, or are from, different Nations. |
| | 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. |
| | organization | An Organization is a corporate or similar institution. The members of an Organization typically have a common purpose or function. Note that this class also covers divisions, departments, etc. of organizations. For example, both the Shell Oil Corporation and the accounting department at Shell would both be instances of Organization. Note too that the existence of an Organization is dependent on the existence of at least one member (since Organization is a subclass of Collection). Accordingly, in cases of purely legal organizations, a fictitious member should be assumed. |
| | physical | An entity that has a location in space-time. Note that locations are themselves understood to have a location in space-time. |
