Elements

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

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

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

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

Object page

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.

Quality page

Additional information

Example

That copy of Divina Commedia is a book (Object), the porosity (Quality) of the paper used is 5 mls/min (Abstract). The Rock Music Festival (Event) is organized by a friend of mine (Object).

Figure shows the UML diagram of this scenario.
