ExtractHL7Attributes

ExtractHL7Attributes 2.0.0

Bundle: org.apache.nifi | nifi-hl7-nar
Description: Extracts information from an HL7 (Health Level 7) formatted FlowFile and adds the information as FlowFile Attributes. The attributes are named as <Segment Name> <dot> <Field Index>. If the segment is repeating, the naming will be <Segment Name> <underscore> <Segment Index> <dot> <Field Index>. For example, we may have an attribute named "MHS.12" with a value of "2.1" and an attribute named "OBX_11.3" with a value of "93000^CPT4".

Relationships

failure	A FlowFile is routed to this relationship if it cannot be mapped to FlowFile Attributes. This would happen if the FlowFile does not contain valid HL7 data
