Updated Candidate Recommendation: Timed Text Markup Language 2 (TTML2) (2nd Edition)

The Timed Text (TT) Working Group invites implementation of its updated Candidate Recommendation of Timed Text Markup Language 2 (TTML2) (2nd Edition). This document specifies the Second Edition of the Timed Text Markup Language (TTML), Version 2, also known as TTML2 (2e), in terms of a vocabulary and semantics thereof. The Timed Text Markup Language is a content type that represents timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information. It is intended to be used for the purpose of transcoding or exchanging timed text information among legacy distribution content formats presently in use for subtitling and captioning functions.
