This Validation Module defines the Implementation Guide for validating FHIR Resources in ISiK Stufe 5 (Informationssysteme im Krankenhaus) Context. This Module is intended to be used with the gematik Reference Validator.
See the Release Notes file for information about changes.
In order to build the Validation Module, you need the following tools and frameworks:
- Java JDK 25 or later
- Apache Maven 3.9+
- gematik Reference Validator 3.0.0+ (automatically downloaded through Maven)
Additionally, you need internet access, to fetch the FHIR Implementation Guide for ISiK from the official FHIR registry.
You can build the Validation Module with the following command:
mvn clean install
The result will be a .JAR File located in the target directory, which can be used with the gematik Reference Validator
to validate FHIR Resources.
If you don't want to build the Validation Module yourself, you can download the latest version directly from the GitHub Release page.
Follow the documentation at the gematik Reference Validator repository for usage instructions.

You need to define the module-name parameter or, in the configuration YAML file, you need to set the key
