HAPI FHIR - HL7 FHIR Core Artifacts

CI Status (master)

This is the java core object handling code, with utilities (including validator), for the FHIR specification. included in this repo:

• org.fhir.fhir.utilities: Shared code used by all the other projects - including the internationalization code
• org.fhir.fhir.r5: Object models and utilities for R5 candidate (will change regularly as new R5 candidates are released)
• org.fhir.fhir.r4b: Object models and utilities for R4B
• org.fhir.fhir.r4: Object models and utilities for R4
• org.fhir.fhir.dstu3: Object models and utilities for STU3
• org.fhir.fhir.dstu2: Object models and utilities for STU2
• org.fhir.fhir.dstu2016may: Object models and utilities for an early STU3 candidate still used by some implementers
• org.fhir.fhir.convertors: Code to convert between versions, and other version independence code - uses all the above projects
• org.fhir.fhir.validation: The FHIR Java validator (note: based on R5 internally, but validates all the above versions)
• org.fhir.fhir.validation.cli: Holder project for releasing the FHIR validator as as single fat jar (will be removed in the future)

This code is used in all HAPI servers and clients, and also is the HL7 maintained FHIR Validator. In addition, this is the core code for the HL7 maintained IG publisher and FHIR main build publisher. As such, this code is considered an authoritatively correct implementation of the core FHIR specification that it implements.

Building this Project

This project uses Apache Maven to build. To build:

mvn install

Note that unit tests will run, but are currently not set to fail the build as they do not all pass. This is being worked on.

To skip unit tests:

mvn -Dmaven.test.skip install

To clean and rebuild the terminology server caches.

clean

mvn clean -Dfhir.txcache.clean=true   

rebuild

mvn test -Dfhir.txcache.rebuild=true

The source contains cached terminology server responses for testing. If the expected responses have changed in any way, this cache should be cleaned and rebuilt with the above so that subsequent mvn test calls will have the most current responses cached.

IDE Setup

This project uses the Lombok java library, which requires some configuration to work correctly with an IDE. Currently, the project works in Intellij and Eclipse, and you can find instructions on how to configure Lombok for each here.
