The CLIFF Localization Format

CLARION — the independent test suite and benchmark project for CLIFF: conformance fixtures, reference validator, edit-robustness protocol and the measured evidence bundle.

pyclif — MIT-licensed, zero-dependency reference implementation of CLIFF: parser, validator, serializer and bidirectional converters for XLIFF, PO, Fluent, JSON, YAML, CSV, Android and iOS.

CLIFF is a Contextual Localization Integrated File Format: a line-oriented, context-first working file for the whole localization lifecycle — designed for translators and LLM workflows.

CLIFF for JavaScript: a browser-first TypeScript implementation of CLIFF 1.0/1.1 (Contextual Localization Integrated File Format) with strict and tolerant parsers, serializer, validator, and JSON converters for browser and Node.js.
