Table 1 lists the Data Types used by CAV-TEC. Each entry includes a link to the relevant specifications. Note that several Data Types are specified by other MPAI Technical Specifications than CAV-TEC: MPAI-CAE, MPAI-MMC, MPAI-OSD, MPAI-PAF, and MPAI-TFA. Data Types referenced by such Data Types are not listed here but are specified by the relevant Technical Specification.

2 Conformance testing

The Conformance a Data instance conforms with AIH-HSP V1.0 is expressed by one of the two statements:

  1. “Data conforms with the relevant (Non-MPAI) standard” – for Data.
  2. “Data validates against the Data Type Schema” – for Data Object.

The latter statement implies that:

A Data instance Conforms with AIH-HSP V1.0 specified Data Type if:

  1. Its JSON Object validates against its JSON Schema.
  2. Any included JSON Object validates against its JSON Schema.
  3. All Data in the JSON Object:
    1. Have the specified Data Types.
    2. Conform with the Qualifiers signaled in their JSON Schemas. For example, if the data cldata to be UNICODE, it should conform with what the Text Qualifier (MPAI-TFA V1.4) defines as UNICODE.

Note that at this stage the AIH-HSP V1.0 does specifies Conformance Testing for Data Types.

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:

  1. Quality– for example, how well a Scene Descriptors instance represent a scene.
  2. Bias: – for example, how dependent on specific features of the training data is the inference represented by the Data instance.
  3. Legality– for example, whether the Data instance was produced in a jurisdiction at a time by an AIM that complies with the relevant a regulation, e.g., the European AI Act.
  4. Ethics – for example, the data instance complies to a target ethical standard.

Note that at this stage the AIH-HSP V1.0 specifies Performance Assessment only of some Data Types.
