What Is Reference Documentation? ​
Reference documentation provides official definitions and guidance for implementing European mobility data standards. It includes schemas, UML models, reference guides, and technical specifications that ensure consistent interpretation across implementations.
Used by:
- Developers to implement data exchange formats correctly
- System architects to design interoperable platforms
- Public authorities to ensure conformance in data publication
