description: 'Represents the canonical/normalized form of an identifier or value.

|
|
|
**PURPOSE**:
|
|
|
|
While original values may vary in format (spaces, prefixes, case), CanonicalForm
|
|
provides a standardized representation for: - Consistent storage - Deduplication
|
|
and matching - Database joins and lookups - Cross-system interoperability
|
|
|
|
**NORMALIZATION RULES BY STANDARD**:
