Description

An English description of the definition (what distinguishes this sense of the term?).

A state specifies some snapshot of objects in the domain as they exist at some point in time.

Class Diagram Description

An activity cluster provides a basic structure for representing activity specifications. Illustrated in Figure 1, it consists of an activity connected to an enabling and caused state, each of which may be a state tree that defines complex states via decomposition into conjunctions and disjunctions of states.

Figure 2 illustrates the use of the Activity Ontology to describe a class of objects that should be identified as “Drive to Work” activities, where the effect of such an activity is a Conjunctive state. The conjunctive state is decomposed into two terminal states, meaning that it should be interpreted as a state where both sub-states (DriverAtWork and CarAtWork) are true.
