1      Definition

A Data Type describing the arrangement of the Offline Map Objects in a Scene.

2      Functional Requirements

A Basic OfflineMap Scene Geometry must include:

  1. The Basic OfflineMap Scene Geometry Header
  2. The ID of the Basic OfflineMap Scene Geometry.
  3. The ID of the OfflineMap Objects in the OfflineMap Scene.
  4. The Space-Time information of the OfflineMap Objects inside the OfflineMap Scene.

A Basic OfflineMap Scene Geometry may include:

  1. The ID of a Virtual Space (M-Instance) where it is or it is intended to be located.
  2. The ID of a U-Environment where it is or it is intended to be located.
  3. The Qualifiers of the Basic OfflineMap Object Data.
  4. The Space-Time information of the Basic OfflineMap Scene.
  5. Information about this Basic OfflineMap Scene Geometry.
  6. Descriptive Metadata.

5     Conformance Testing

A Data instance Conforms with Basic OfflineMap Scene Geometry (OSD-BOG) if:

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