 Ogg is being developed by Xiph.org. Xiph.org have not made a decision yet on how subtitles and captions are best to be supported inside Ogg.
-Another project called OGM actually branched the Ogg codebase and implemented support for a wide range of proprietary and non-free codecs. For example,  OGM files most often carry video encoded in the MPEG-4 ASP format and audio in Vorbis or AC-3 together with subtitles in SRT, SSA or VobSub format.
 Ogg itself supports CMML, the Continuous Media Markup Language developed by the proposed grantee which is more HTML-like and includes support for hyperlinks. It has been considered to be used for captions and subtitles, but the specifications are still in development. It has to be re-assessed under the current accessibility requirements whether CMML or an extended version of CMML is a useful solution to our problems. A very interesting implementation and use of many of the CMML/Annodex ideas is MetavidWiki (see http://metavid.ucsc.edu/), which is an open source wiki-style social annotation authoring tool.
