The Validation Service is responsible for validating FHIR resources according to the HL7 FHIR specification, based on predefined FHIR profiles, provided from RKI (Robert Koch Institute). These profiles are loaded from the file system during the service startup phase. Please note that the profiles are not part of this repository. In a Kubernetes environment, the FHIR profiles are mounted to the service's file system from a dedicated OCI container image.
This service is a Spring Boot-based application that processes HTTP requests and leverages appropriate HAPI FHIR library methods to perform the following tasks:
- Message Parsing
- Validation
- Response Serialization
See ReleaseNotes for all information regarding the (newest) releases.
The application requires the DEMIS FHIR Profiles. This image is maintained in DockerHub: demis-profile-snapshots.
The profiles are require to execute the integration profile tests included in this repository. With -PskipProfileTests
you can skip these tests if you don't have profiles locally.
At runtime execution the profile files must be available in a folder and this folder must be specified through the
environment variable FHIR_PROFILES_BASEPATH
.
mvn clean verify
The Project can be built with the following command:
mvn -e clean install -DskipTests=true
build with docker image:
docker build -t validation-service:latest .
The Docker Image associated to the service can be built alternatively with the extra profile docker
:
mvn -e clean install -Pdocker
or if you don't have the profiles
mvn -e clean install -PskipProfileTests -Pdocker
The application can be started as Docker container with the following commands assuming that the profile snapshots are located in directory /profiles/5.2.0/Fhir
docker run --rm --name validation-service \
-v $(pwd)/profiles:/profiles \
-p 8080:8080 \
-e FHIR_PROFILES_BASEPATH=/profiles \
-e FHIR_PROFILES_VERSIONS=5.2.0 \
