Standards

How are messages represented in different standards:

v2 Messaging

In v2.x messaging is the standard transmission protocol. The content is encapsulated by technical segments:

(simple) trigger message:

• MSH
• [EVN]
• PID
• …

response ACK message:

• MSH
• MSA
• …

MSH conveys individual message instance identifiers. In a response, the MSA refers to the instance identifier of the message to which it is the response to.

FHIR Messaging

In FHIR, messages are transmitted in a batch that is encapsulated in a bundle:

• Bundle
  • MessageHeader
  • …

V3 Messaging
