Welcome to the home page for the MessageFormat Working Group, a subgroup of the Unicode CLDR-TC.
The MessageFormat Working Group (MFWG) is tasked with developing and supporting an industry standard for the representation of localizable message strings. MessageFormat is designed to support software developers, translators, and end users with fluent messages and locally-adapted presentation for data values while providing a framework for increasingly complex features, such as gender, inflections, and speech. Our goal is to provide an interoperable syntax, message data model, and associated processing that is capable of being adopted by any presentation framework or programming environement.
The MessageFormat 2 specification has been approved by the CLDR Technical Committee and is now a stable part of the LDML specification. It is now recommended for implementation and adoption.
Some default functions and items in the u: namespace are still in Draft status.
Feedback from users and implementers might result in changes to these capabilities.
The MessageFormat Working Group and CLDR Technical Committee welcome any and all feedback, including bugs reports, implementation reports, success stories, feature requests, requests for clarification, or anything that would be helpful in supporting or enhancing the specification and promoting widespread adoption.
Do you have feedback on the specification or any of its elements? file an issue here
We invite feedback about implementation difficulties, proposed functions or options real-life use-cases, requirements for future work, tooling, runtime APIs, localization workflows, and other topics.
- General questions and thoughts → post a discussion thread.
- Actionable feedback (bugs, feature requests) → file a new issue.
We are looking for participation from software developers, localization engineers and others with experience in Internationalization (I18N) and Localization (L10N). If you wish to contribute to this work, please review the information about the Contributor License Agreement below.
