Bridging v2 to FHIR
summary
Project maps actual HL7 v2 usage into FHIR R4 by mapping commonly used messages (ADT A01, ORM/O01, ORU, VXU, SIU, OML) and the cumulative V2 standard up to 2.9 into FHIR resources, targeting a FHIR message bundle output. Work uses CSV spreadsheets reviewed collaboratively, converted into ConceptMap artifacts in GitHub, validated with sample messages and the FHIR validator, and drives extension requests (example: veteran military status). Plan aims for a content ballot in September and publication around mid‑2022.
