Actors

Subscriptions are operations which typically involve three actors:

1. Server
2. Client or Subscriber
3. Endpoint

FHIR Server

Server refers to the FHIR application or applications acting as the subscription provider. This includes the responsibilities of implementing one or more SubscriptionTopics, managing Subscriptions, and sending notifications.

FHIR Client / Subscriber

Client or Subscriber refers to the application or applications acting as subscriber. This includes the responsibilites of acting as a FHIR client (to create a Subscription) and receiving notifications on a supported channel.

Endpoint

Endpoint refers to the portion of the client which is responsible for receiving notifications, if applicable. For example, when using the rest-hook channel type the endpoint is the HTTP server listening for notifications. While part of the client, it is often useful to refer to the endpoint separately for clarity.
