Actions are the interventions, events, and ongoing processes in the situation-independent part of the Unconventional Conflict Ontology that are performed by Actors. Actions directly cause changes. The Action Ontology has seven Action categories, 20 subcategories, and 392 Action elements. These Action elements constitute the classes that would be the lowest level of a DIME ontology. Figure 4.1 provides an illustration of an Action: “eat.” This chapter describes the organization of the Action Ontology and all of its elements, along with the types of Metrics associated with each element.
