/**
* Identifies the {@link DomainRing} in an onion architecture. The domain ring is the inner-most ring in the
* onion architecture and is only coupled to itself. It models the truth of the business domain by consisting of
* behaviour (logic) and the required state (data).
*
* Compared to the 4-ring onion architecture in which the domain is split into domain model and domain services, the
* 3-ring version combines those 2 rings so that it implements behavior (logic), state (data), and interfaces needed for
* e.g. storing and retrieving data, i.e. repository interfaces.
