This repository covers the TTML Profiles for Internet Media Subtitles and Captions (IMSC) family of specifications. The latter is intended to be augmented with additional versions over time. Each version will potentially correct errors, add non-substantive information, introduce minor features or make significant changes. This document lists each member of this family of specifications.
See the ttml-imsc cover page.
All issues against IMSC are tracked here. Milestones are used to assign issues to specific versions of IMSC.
The imsc-tests repository contains the tests for IMSC implementations, which are also used for the IMSC implementation reports.
