They consist of the following components as follows: CMML Continuous Media Markup Language is a XML markup language for time-continuous data such as audio and video. The main principles of CMML are as follows: Enables the description of structure for a media file through marking up temporal clips Allows attachment of hyperlinks and annotations to the clips. Used for authoring of Annodex content through the stream tag. Example of CMML Content <cmml> <stream timebase="0"> <import src="galaxies.mpg" contenttype="video/mpeg"/> </stream> <head> <title>Hidden Galaxies</title> <meta name="author" content="CSIRO"/> </head> <clip id="findingGalaxies" start="15"> <a href="http://www.aao.gov.au/galaxies.anx#radio"> Related video on detection of galaxies </a> <img src="galaxy.jpg"/> <desc>What's out there?</desc> <meta name="KEYWORDS" content="Radio Telescope"/> </clip> </cmml> The origin of the CMML document, along with further documentation and standards can be found at Annodex CMML Standard Version 2.1 Annodex File Format 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 to allows for internet servers and proxies to manage temporal subparts and reconstruct files from annodexed clips. This introduces the following stream types: A Skeleton meta-header stream a CMML annotation stream Further information can be found at Annodex Annotation Format for Time-continuous Bitstreams, Version 3.0 Time intervals in URIs To include time-continuous content such as audio and video media into the Web, it is necessary to be able to point hyperlinks into such content to address temporal offsets.
