The Types of entities Content OP locally defines the following ontology elements:

Class Abstract (owl:Class) any entity that cannot be located in space-time. E.g. mathematical entities, formal semantics elements, regions within dimensional spaces, etc.

Abstract page

Class Event (owl:Class) any physical, social, or mental process, event, or state. More theoretically, events can be classified in different ways, possibly based on aspect (e.g. stative, continuous, achievements, etc.), or on agentivity, typical participants (e.g. human, physical, abstract, food, etc.).

Event page

Class Object (owl:Class) any physical, social, or mental object, or a substance.

Object page

Class Quality (owl:Class) any aspect of an entity (but not a part of it), which cannot exist without that entity. For example, the way the surface of a specific physical object looks like is a Quality.

Additional information
