The Dynamic Evidence Type Version describes the structure and behaviour of a Dynamic Evidence Type at a particular point in time. Dynamic Evidence Type Versions have effective dates to support the evolution of Evidence Types over time. A Dynamic Evidence Type Version applies from its effective date, and will be used to maintain Case Evidence data from this date onwards. However, unlike Non-Dynamic Evidence, it is possible for multiple Versions of Dynamic Evidence to exist in the system, as long as all of these Versions have different effective dates; there can only ever be a single Dynamic Evidence Type Version active for a particular effective date.
The next two sections explore the details of Dynamic Evidence Types and Dynamic Evidence Type Versions in greater depth.
