Lab Modules

What you can test

Tools for working with FHIR resources, validation and synthetic data. Statuses reflect current project maturity.

Resource Builder

Planned

Create and edit FHIR R4 resources. View JSON output and validate against base profiles.

Validator

Planned

Validate FHIR JSON and XML against R4 rules and profiles. Supports Bundles, Patient Summary and ePrescription.

Mock Server

In Progress

Simulated FHIR REST API for CRUD operations, search and transaction testing based on HAPI FHIR R4.

Synthetic Data

Planned

Generate realistic fictional FHIR datasets: patients, encounters, observations, medications and Patient Summary.

Terminology Explorer

Planned

Explore CodeSystem, ValueSet and ConceptMap. Work with LOINC, SNOMED CT, ICD-10 and ATC examples.

Profile Explorer

Planned

Inspect StructureDefinitions, constraints, Must Support elements and example resources for EHDS profiles.

Future Direction

EHDS and EHRxF Scenarios

As the lab matures, it will expand to cover European Health Data Space interoperability scenarios using synthetic data aligned with EHRxF profiles and EHDS use cases.

Planned

Patient Summary

IPS-based Patient Summary aligned with EHDS and EHRxF.

Planned

ePrescription

Cross-border ePrescription and eDispensation workflows.

Planned

Laboratory Results

Structured lab reports using FHIR DiagnosticReport and Observation.

Planned

Cross-border Care

MyHealth@EU interoperability scenarios using synthetic data.
