Describing State Concepts
The notion of state of a concept is represented by the State Concept.
*A state concept is a situation in a concept life cycle during which it satisfies certain conditions, executes a certain activity or waits for a concept event. A state concept represents a time interval of which limits are two concept events. A state concept is a phase through which the concept passes during its life cycle.
For example, the same subscription holder can pass from "Child" state to "Adolescent" state, then to "Adult" state and finally "Senior".
Passage from one state concept to another can be conditioned by an Event Concept.
*An event concept represents an event occurring during concept life, for example a change of season. An event concept marks the impact on a concept of a phenomenon internal or external to the concept. Concept events can be distinguished as concept start events, end events and intermediate events.
For example, passage from one state to another can be connected to a event, a "Birthday" for example.
