1      Definition

A Data Type including Visual Data and an optional Visual Qualifier.

Visual Data can be made perceptible by a visual device or visible to a human when rendered.

2      Functional Requirements

A Visual Basic Object may include:

  1. The ID of a Virtual Space (M-Instance) where it is or is intended to be located.
  2. The ID of the Visual Object.
  3. The ID(s) of Parent Object(s) supporting two cases:
    1. The Parent Object has spawned two (or more) Objects.
    2. Two (or more) Parent Objects have merged into one.
  4. The Space-Time information of Parent Objects in an M-Instance.
  5. The ID(s) of Child Object(s).
  6. The Space-Time information of Child Objects in an M-Instance.
  7. The Space-Time information of the Visual Object in an M-Instance.
  8. The Object Properties expressed by the Visual Data Qualifier.
  9. The Visual Data Qualifier.
  10. The Visual Data Annotations, including:
    1. Annotation
    2. Annotation Space-Time
    3. Process Action ID
  11. The Visual Object-specific Data:
    1. Visual Data Qualifier.
    2. Visual Data Annotation.

5     Conformance Testing

A Data instance Conforms with Visual Object (OSD-VIO) V1.2 if:

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