Note: ContextItems do not have IDs because they never stand alone; they are always embedded within other objects.

Essentially a Representation ID. We are talking about an ID of an abstract class because ContextItem values can correspond to:

  • NumericRepresentationValues (e.g., FSA Area of a field)

  • EnumeratedRepresentationValues (e.g., PLSS Prime Meridians)

  • String Representations (e.g., US Driver's License number)

Value

String

0..1

Optional because container ContextItems (e.g., PLSS) would not have a Value.
