Unique Identifier

An identifier is required to differentiate between sets of Objective Status information and it is required that the identifier is set before any other status elements. SCOs may have multiple objectives so, for objectives to be easily tracked within the SCO, all objectives must be unique to each SCO. For example, the objectives for this SCO are:

- Identify the purpose of Objectives
- Identify the Objective Status Elements
- Recognize the purpose of a unique identifier
- Recognize the reasons for tracking Objectives.

If each of these four objectives were named Objective_1, then how would one know which of the four objectives a learner has met? If the objectives were uniquely identified as Objective_1, Objective_2, Objective_3 and Objective_4, then one can distinguish which objectives the learner has met.

Based on your organization's needs, some considerations should be made about making the identifier globally unique. Many situations and use cases have been presented where this uniqueness is required.
