lifecycle
Information describing changes and events in an object's past, present, or future existence.
Lifecycle fields describe the changes and events which occur in the history of an object.
A lifecycle description concerns the object over time. It can describe a particular event or a stage during which the object has a given condition or status.
Status describes a stage of existence, while a lifecycle event concerns a moment or phase of change. An object's physical dimensions describe a different aspect of it.
