An Activity Service represents an atomic business unit of work and has a set of steps involving system-to-system interactions. Activity Services may also warrant orchestration. In some CASES, there may be matching application CAPABILITIES. These are exposed as MEDIATOR services on the service BUS. Activity Services can act upon multiple canonical MESSAGES and be consumed by participating applications and process services. The structure of the message is either canonical or a user-defined format.
