New article: Understanding the New Language Tags
The new version of BCP 47 is expected to shortly replace RFC 3066. The tags defined by ‘RFC 3066bis’ address a number of long standing problems with language identification, leading, hopefully, to richer language-aware features in our software and better support for language in our documents.
This article provides an overview of the changes in store for language tags. It describes the structure of future language tags, the current status of the work, and remaining work to be done. Author: Addison Phillips, Yahoo!
