1      Definition

A Data Type including a collection of Basic RADAR Objects.

A RADAR Object can have a hierarchical structure where RADAR Objects contain Basic RADAR Objects and RADAR Objects.

2      Functional Requirements

A RADAR Object may include:

  1. ID of a Virtual Space (M-Instance) where it is or intended to be located.
  2. ID of the RADAR Object.
  3. Space-Time information of the RADAR Object.
  4. Basic RADAR Object and RADAR Objects included in the RADAR Objects.
  5. Annotation data set including:
    1. Annotations
    2. Space-Times of the Annotations.
    3. Rights to perform Actions on the RADAR Object.
  6. The Rights that may be exercised on the RADAR Object.

Note that.

  1. A RADAR Object that does not include Sub-Scenes and only one Basic RADAR Object is a Basic RADAR Object.
  2. The Space-Time information of a Basic RADAR Object and RADAR Object included in a RADAR Object may be superseded by the Space-Time information of the RADAR Object containing them.

5     Conformance Testing

A Data instance Conforms with RADAR Object (OSD-RAO) if:

  1. The Data validates against the RADAR Object’s JSON Schema.
  2. All Data in the RADAR Object’s JSON Schema
    1. Have the specified type
    2. Validate against their JSON Schemas
    3. Conform with their Data Qualifiers.
