Infrastructure And Messaging Work Group | Maturity Level: 0 | Draft | Compartments: Not linked to any defined compartments |
Defines the characteristics of a message that can be shared between systems, including the type of event that initiates the message, the content to be transmitted and what response(s), if any, are permitted.
Implementers should be familiar with the messaging concepts and descriptions found in Messaging using FHIR Resources before working with this resource.
