Harmonizing Media Annotations and Media Fragments

W3C´s Video in the Web activity aims at a better integration of media within the Web. In this paper, we show how two specifications currently under development within this activity, i.e., Media Fragment URIs and Media Annotations, can be combined within media-enabled Web applications. More specifically, we introduce a number of extensions for the Media Annotations ontology in order to close the gap with Media Fragment URIs. Further, a fully integrated Web application has been developed that shows how both specifications can work together within an HTML5 environment. This application relies on NinSuna, our media delivery platform targeted at multichannel publication that provides server-side support for both Media Fragment URIs and Media Annotations.
