Figure 1. A minimalistic example of an ontology. Instances of the Process class are connected to Object instances via the has Participant relationship. The Manufactured class is a child class of the Object class, meaning that all properties and relationships can be inferred from Object to Manufactured. A Manufactured object is composed of other Manufactured parts. This mereological perspective is represented by the hasPart relationship.
