FHIR Mapping
The strategy was originally implemented by Kwateng on 06.08.2017. commit 881e70acf638df9ef8572e4ec96e19e0c5057828
This is a suggestion on how to map OpenMRS DrugOrder object into FHIR TBD.
Fields which didn't match into FHIR representation are marked on red. Keyword extension means that FHIR Extension has to be used to synchronize this field.
Fields which partially match into FHIR representation are marked on orange.
