HL7 Parser
The HL7 Parser converts HL7 v2.x segments (MSH, PID, PV1, OBX, …) into a structured internal representation used by mapping and archival.
Parsing errors produce NAK responses so hospitals can retry or alert their interface engine — silent drops are never acceptable on ADT/ORU paths.
Behaviour
- Validates message type and trigger event (e.g. ADT^A01, ORU^R01).
- Normalises encoding and segment delimiters per MSH.
