5     Conformance Testing

A Data instance Conforms with Visual Basic Scene Descriptors (OSD-VBS) V1.2 if:

  1. The Data validates against the Visual Basic Scene Descriptors’ JSON Schema.
  2. All Data in the  Visual Basic Scene Descriptors’ JSON Schema
    1. Have the specified type.
    2. Validate against their JSON Schemas.
    3. Conform with their Data Qualifiers.
