Use

Multiple Origin Composition (MOC) is the ability to collect data from different backend systems, aggregate them in one single service and updating different backend systems while using the same user. This is now extended to subscription management where, an administrator can configure subscriptions on behalf of a user in multiple backend systems. This means that the administrator can create, read, update, delete, and query subscriptions across multiple systems.
