The following special considerations - and features - are handy to keep in mind when working with the FHIR Mapper.
FHIR Mapper supports logging with
log, but it is a bit different from the specification:
login the start source field
enclose the log statement in double quotes
enclose plain text within the log statement in single quotes
concatenate values with
src.patientName as s log"'patient name is ' + $this.patientName" -> tgt.name as t, t.text = s;
check FHIRPath statements (documentation) in double quotes:
src.contact as s where "address.exists()" -> ...
In order to transform data in bulk, submit it in CSV format. JSON format supports only individual transformations.
