Aug 1, 2025In August 2025, delivered key CLDR improvements focused on currency data quality, localization coverage accuracy, and data integrity, while stabilizing exemplar data for reliable downstream processing. The team completed a refactor of currency formats generation with enhanced options and documentation, reverted Myanmar exemplars to a stable version to restore character set definitions, and implemented stricter data validation to prevent illegal escape characters. These changes reduce data risk in production, improve localization reliability across locales, and strengthen the foundation for downstream tooling and analytics.

Nov 1, 2024In 2024-11, delivered the LDML Documentation Improvements: Identifiers and EBNF Clarifications for the unicode-org/cldr repository. Consolidated and extended documentation on LDML unit syntax, well-formedness constraints, and EBNF formatting to improve accuracy and usability for CLDR specification users. Implemented three commits addressing CLDR-15948: clean up well-formedness/validity constraints, fix wording in tr35-general.md, and add additional well-formedness clauses. Impact: clearer guidance for implementers, reduced ambiguity in LDML interpretation, and improved maintainability of CLDR docs. Skills demonstrated include documentation engineering, LDML/EBNF syntax understanding, and Git-based collaboration.
