The W3C recommendation on the Media Fragment URI specification is an important part of the technological solution promoted by MediaMixer. It provides a standardised manner to refer to spatial and temporal fragments of a media item with the goal that this can be used across software systems in a media workflow. Now MediaMixer has published links on its community portal to two background presentations on Media Fragments:

• “Addressing and annotating Media Fragments” is an introductory tutorial to the media fragment specification
• “Implementing the Media Fragments URI specification” adds more technical detail especially in terms of media server implementation supporting media fragments
