Definition

A list (also sometimes called a pick list) is a limited set of terms arranged as a simple alphabetical list or in some other logically evident way. Lists are used to describe aspects of content objects or entities that have a limited number of possibilities. Examples include geography (e.g., country, state, city), language (e.g., English, French, Swedish), or format (e.g., text, image, sound).

Requirements

The system should allow the user to:

• Create a controlled list of unique terms
• Control the order of terms in a controlled list
• Assign the controlled list to a field or fields
• Add new terms to a list
• Invalidate list terms

Use Cases

From presentation noted below:

In a well-constructed controlled list:
