FHIR custom implementation

This documentation covers advanced system configuration, for Java developers.

When Geoprism Registry exchanges data with a Fast Healthcare Interoperability Resources (FHIR) server through a FHIR synchronization, the data is transformed by an implementation:

• An export implementation (FhirDataPopulator) turns list data into FHIR resources.

• An import implementation (FhirResourceProcessor) turns FHIR resources into Geo-Objects.

Geoprism Registry includes these implementations, which you can choose in a synchronization configuration without writing any code:

Implementation	Type	Class
Basic Export Implementation	Export	net.geoprism.registry.etl.fhir.BasicFhirDataPopulator
mCSD Export Implementation	Export	net.geoprism.registry.etl.fhir.MCSDFhirDataPopulator
Basic Resource processor	Import	net.geoprism.registry.etl.fhir.BasicFhirResourceProcessor

If these don't fit your data, a developer can write a custom implementation. Implementations are found with the Java ServiceLoader, so you add one by building a JAR that registers its classes. The steps are:

1. Maven project setup

2. Create a custom implementation for exporting data to FHIR, Create a custom implementation for importing data from FHIR to Geoprism Registry, or both

3. Register the implementations with the Java Services architecture

4. Deploy implementation to server
