Shown below is an example of how a number of OpenMRS module objects would map to FHIR resources, as proposed by Grahame Grieve.
The left side of the relationship indicates the OpenMRS attribute, while the right indicated the FHIR resource mapping.

FHIR Family history resource is map to patient's relations in OpenMRS as follow
| Code Block |
|---|
|
Integer relationshipId :: not mapped
Person personA :: If PersonA is the requesting patient of family history then it will be mapped to FamilyHistory.subject else person will be map to relation attributes accordingly
Person's Relationships will be map as follow
RelationshipType relationshipType ::
String aIsToB :: FamilyHistory.relation.relationship (if patient resource relation ship is A to B)
String bIsToA :: FamilyHistory.relation.relationship (if patient resource relation ship is B to A)
Person personB :: If PersonA is the requesting patient of family history then it will be mapped to FamilyHistory.subject else person name will be map to FamilyHistory.relation.name
Related person bithday :: FamilyHistory.relation.born[x]
