Smile CDR has native support for the HL7 v2.x (aka "Version 2") protocol. This support includes a set of standard transformations between the data model of the HL7 v2.x protocol and the FHIR data model.
This support includes both Inbound support (receiving HL7 v2.x messages from an external system and converting them to FHIR) as well as Outbound support (automatically generating HL7 v2.x messages based on content that is stored in the repository and transmitting these messages to a remote system).
The following diagram shows the processing path for Inbound HL7 v2.x Support.
See HL7 v2.x Support: Inbound for information on how to set this up.
The following diagram shows the processing path for Outbound HL7 v2.x Support.
See Outbound HL7 v2.x for information on how to set this up.
