1. Technical Specifications
Table 1 provides the full list of Data Types specified by CAE-6DF V1.0 with links to the pages dedicated to Data Types. Each of these includes Definition, Functional Requirements, Syntax, Semantics, Conformance Testing, and Performance Assessment.

2 Conformance testing
The Conformance a Data instance conforms with CAE-6DF V1.0 is expressed by one of the two statements:
- “Data conforms with the relevant (Non-MPAI) standard” – for Data.
- “Data validates against the Data Type Schema” – for Data Object.
The latter statement implies that:
A Data instance Conforms with CAE-6DF V1.0specified Data Type 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.
3. Performance Assessment
Performance is an umbrella term used to describe a variety of attributes – some specific of the application domain served by a specific Data Type. Therefore, Performance Assessment Specifications provide methods and procedures to measure how well a Data instance represents an original Data entity. Performance of an Implementation includes methods and procedures for all or a subset of the following characteristics:
- Quality– for example, how well a Scene Descriptors instance represent a scene.
