ubl
Part of Speech
proper noun; language identifier; code
Semantic Domain
Language; Language documentation; Linguistic identity
Notes
ubl is the identifier, not the language name. In ISO 639-3, the three-letter code serves as a stable identifier for the language, while the associated reference name may be revised.
For Change Request 2026-002:
- ISO 639-3 identifier: ubl
- Reference name at filing: Buhi’non Bikol
- Proposed reference name: Boie’nen
- Requested action: change of reference name only
- Identifier affected: none; ubl remains unchanged
Accordingly, Boie’nen, Buhi’non Bikol, and ubl should not be treated as interchangeable kinds of labels: Boie’nen and Buhi’non Bikol are language names, whereas ubl is the permanent ISO 639-3 identifier associated with the language.
Linguistic History
The ISO 639-3 identifier ubl predates Change Request 2026-002 and was associated with the reference name Buhi’non Bikol when that request was filed. In 2026, Change Request 2026-002 proposed that Boie’nen replace Buhi’non Bikol as the ISO reference name, while preserving ubl as the language identifier.
