OMH Header to FHIR Observation Detailed Mapping

The following Table provides the detailed mapping for the OMH Header to the OMH to FHIR Observation Profile TODO: add link to profile:

Index	OMH Header Element	FHIR Attribute	Mapping Instructions
1	header-1.2.json	OMH to FHIR Observation Profile
2.1	header.id		concatenation of "urn:uuid:" + header.id
2.2	header.id	identifier[0].system	fixed to "urn:ietf:rfc:3986"
3	header.creation_date_time	issued	= header.creation_date_time
4	header.schema_id	None
5	header.schema_id.namespace	None
6A.1	header.schema_id.name	category[0].coding[0].code	Map header.schema_id.name to column "Observation.category.code" using the OMH DataPoint Element to FHIR Element Mapping Table
6A.2	header.schema_id.name	category[0].coding[0].system	fixed to "http://hl7.org/fhir/observation-category"
6B.1	header.schema_id.name	code.coding[0].code	Map header.schema_id.name to column "Observation.code.code" using the data_point_mapping_table
6B.2	header.schema_id.name	code.coding[0].system	Map header.schema_id.name to column "Observation.code.system" using the data_point_mapping_table
6B.3	header.schema_id.name	code.coding[0].display	Map header.schema_id.name to column "Observation.code.display" using the data_point_mapping_table
7	header.schema_id.version	None
8	header.acquisition_provenance	None
9	header.acquisition_provenance.source_name	device.display	= header.acquisition_provenance.source_name
10.1	header.acquisition_provenance.source_data_point_id	identifier[1].value	concatenation of "urn:uuid:" + header.acquisition_provenance.source_data_point_id
10.2	header.acquisition_provenance.source_data_point_id	identifier[1].system	fixed to "urn:ietf:rfc:3986"
11	header.acquisition_provenance.source_creation_date_time	None

13.1	header.acquisition_provenance.modality	device.extension[0].valueCode	= header.acquisition_provenance.modality
13.2	header.acquisition_provenance.modality	device.extension[0].url	fixed to "http://www.fhir.org/mfhir/StructureDefinition/extenion-modality"
