What Are Reference Implementations? ​
Reference implementations demonstrate how to correctly use or integrate a specific mobility data standard. They provide proven, reusable examples that help developers, data providers, and public authorities understand how to build interoperable solutions.
They are useful for:
- Developers learning how to use a standard in practice
- System integrators implementing compliant interfaces
- Public authorities evaluating best practices and conformance
Types of Reference Implementations ​
| Type | Description | Example |
|---|---|---|
| Data Exchange APIs | Implementations of DATEX II, SIRI, or NeTEx services | DATEX II REST API Reference |
| Publishing Workflows | Sample pipelines for data publication on NAPs | NeTEx → NAP Publisher Demo |
| Metadata Catalogs | Example DCAT-AP / mobilityDCAT-AP portals | Open Mobility Metadata Portal |
| End-to-End Solutions | Complete integration demos showing multiple standards | Cross-Standard Integration Demo |
Common Use Cases ​
Learning and Experimentation ​
Explore working codebases to understand how standards are applied.
Rapid Prototyping ​
Use example implementations as starting points for new projects.
Conformance Testing ​
Compare your implementation against reference systems to ensure compliance.
Demonstrations and Training ​
Support workshops or technical documentation with live examples.
Example Tool ​
DATEX II REST API Reference
- Open-source implementation of the DATEX II REST interface
- Demonstrates schema validation and payload exchange
- Ideal for learning and integration testing
- Developed under the CEN/EN 16157 framework
