The HL7 v2 processing module is expected to process HL7 v2 messages and store these within OpenMRS's data model. It should also provide functions to retrieve information from OpenMRS and construct this as a HL7 v2 messages as required.
Alternatives for HL7 V2 message processing
Currently, the RHEA implementation uses the RHEASHRAdapter module for hl7 message generation. Another alternative is the HL7Query module, which was built by OpenMRS developers in response to the use cases and requirements highlighted by the development of the RHEASHRAdapter module. Therefore, the hl7 generation component of the HL7Query module may be used for the second phase of this effort.
