2.48 Resource MessageDefinition - Content

Infrastructure And Messaging Work GroupMaturity Level: 1 Trial UseSecurity Category: Anonymous 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.

2.48.1 Scope and Usage

Implementers should be familiar with the messaging concepts and descriptions found in Messaging using FHIR Resources before working with this resource.

This resource is referenced by CapabilityStatement, itself and MessageHeader
