Open source implementations of Messaging?

Howdy - I’m looking for a project that supports FHIR messaging, preferably with Kafka.


Most of the FHIR reference implementations will support creating and validating FHIR message bundles and can handle calls to the $process-message endpoint. However, FHIR doesn’t actually define any standard MessageDefinitions, so you’d need to write custom code to handle the logic for the specific messages you want to send or receive. (Most FHIR implementations don’t use messaging at all. Where it is used, the content tends to be defined within the scope of a small community.)
