ADAPT - ContextItem Discussion

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

ContextItem

Attribute	Type	Multiplicity	Description
ContextItemType	Integer	1	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.
ContextItems	ContextItem	0..*	Mechanism to implement hierarchy, e.g., PLSS
Code	String	1
ValueUOM	String	0..1
NestedItems	ContextItem	0..*
