public interface IdentifiableEntity
extends Serializable

An identifiable entity is a serializable business entity that is uniquely identifiable over the time and over different runtime. All entities to be persisted should implement this interface. The persistence of an identifiable entity should be ensures by a EntityRepository. Because an identifiable entity is a business object, it is strongly recommended to expose the business operations related to the entity itself directly within its interface. In the same way, we recommend to perform repository related operations through the entity itself.
