NOTES:

Identifiers may be unique or non-unique, formal or informal, human-readable or machine-readable. Their primary purpose is to allow entities to be distinguished from other entities within a naming or classification system.

CONTROL TEXT OBSERVATION:

Before something can be tracked, discussed, remembered, categorized, or managed, it must be distinguishable. Identifiers function as the basic units of reference within naming systems, allowing reality to be partitioned into recognizable entities that can be individually referenced and organized.
