Language tags provide a means of identifying the language used by information in many contexts. The underlying standard for Internet technologies (RFC 3066, formerly RFC 1766) has been undergoing a set of revisions.
Locale identifiers are sometimes confused with language tags (since the latter is often used to infer the former). The W3C Internationalization working group is working on developing guidelines and standards for identifying locales in Web technologies.
This presentation reviews the history, status, and structure of these standards efforts, with a focus on the recent improvements in language tags and the most recent information on progress in developing locale identifiers.
