Annodex is an encapsulation format, which interleaves time-continuous data with CMML markup in a streamable manner. The Annodex format is built on the Ogg encapsulation format, introducing:

• a Skeleton meta-header stream
• a CMML annotation stream

This allows for internet servers and proxies to manage temporal subparts and reconstruct files from annodexed clips.

Abstract

This specification defines a file format for annotating and indexing time-continuous bitstreams for the World Wide Web. The format has been named "Annodex" for annotating and indexing. The Annodex format enables the specification of named anchor points in time-continuous bitstreams together with textual annotations and hyperlinks in URI format. These anchor points are merged time-synchronously with the time-continuous bitstreams when authoring a file in Annodex format. The ultimate aim of the Annodex format is to enable an integration of time-continous bitstreams into the browsing and searching functionality of the
World Wide Web.
