5 Conformance Testing
A Data instance Conforms with Health Data (CAE-UCM) if:
- Its JSON Object validates against its JSON Schema.
- Any included JSON Object validates against its JSON Schema.
- All Data in the JSON Object:
- Have the specified Data Types.
- Conform with the Qualifiers signaled in their JSON Schemas.
