Extending the mapping of an existing FHIR Resource

Updated on October 19, 2021

The mapping of the API response data to logical data classes in Pega Foundation for Healthcare is configured using appropriate data transform rules as mentioned in the Key Rules for each Resource. The current mapping accounts for majority of data needed for business processing. To extend the mapping to include a missing attribute, copy and extend the pre or post data transform rules in your application layer depending on the need.

Pega Foundation for Healthcare

You may refer ‘MapToPatients4’ mapping datatransform.

Note: The above mapping Data transform rule is marked as final and you cannot override this rule in your layer. So, we provided ‘Pre_MapToPatiensts4_Ext’ and ‘Post_MapToPatientss4_Ext’ data transforms for any extensions in your layer. Both rules are marked for extension as shown below.

Note: Refer to the FHIR Resource Mapping document for details on pre-configured mapping for supported FHIR Resources.
