2.15 Resource MessageHeader - Content

Infrastructure And Messaging icon Work GroupMaturity Level: 4 Trial UseSecurity Category: Not Classified Compartments: Device, Practitioner

The header for a message exchange that is either requesting or responding to an action. The reference(s) that are the subject of the action as well as other information related to the action are typically transmitted in a bundle in which the MessageHeader resource instance is the first resource in the bundle.

The MessageHeader resource is defined in order to support Messaging using FHIR resources. The principal usage of the MessageHeader resource is when messages are exchanged. However, as a resource that can be used with the RESTful framework, the MessageHeader resource has the normal resource end-point ([base-url]/MessageHeader), which is used to manage a set of static messages resources. This could be used to make an archive of past messages available. Creating or updating Message resources in this fashion does not represent the actual occurrence of any event, nor can it trigger any logic associated with the actual event. It is just for managing a set of message resources.

PathValueSetTypeDocumentation
MessageHeader.event[x] ??Example
MessageHeader.reason ExampleMessageReasonCodes Example

Example Message Reasons. These are the set of codes that might be used an updating an encounter using admin-update.

MessageHeader.response.code ResponseType Required

The kind of response to a message.

  • There is no persistent identifier on MessageHeader that identifies the specific triggering event for the message - any such identity must be determined from the payload of the message.
  • The resources referenced by the enterer, author and responsible elements may all be included in the message bundle or left out on the basis that the recipient (and any intermediaries) are able to locate/resolve the resources independently. The former would be suitable for loosely coupled systems, and the latter for tightly coupled systems. The messaging Capability statement for an application may reference a Structure Definition that describes how the bundling occurs
  • The actual content of the focus resource is specified for each message event (see the list on the messaging page). Any resources referenced in the focus element are always included in the bundle
  • If MessageHeader.source.endpoint and MessageHeader.destination.endpoint, are literal URLs, then they SHOULD identify the addresses to which messages can be delivered. If they are logical URIs (i.e. non-dereferenceable), message delivery intermediaries must know how to deliver the message to the destination application.
  • The time of the event will be found in the focus resource. The time of the message will be found in Bundle.timestamp
  • The author and the receiver are not the actual technical systems - these are the human or organizations that make use of the technical systems
  • A receiver is not obligated to reject messages which do not explicitly identify it as receiver (e.g. a tracker will get messages that are destined for some other system)
  • The value set MessageEvent is populated by the authors of the resources declaring the events
