An Architecture for Open Cross-Media Annotation Services
The emergence of new media technologies in combination with enhanced information sharing functionality o ered by the Web provides new possibilities for cross-media annotations. This in turn raises new challenges in terms of how a true integration across di erent types of media can be achieved and how we can develop annotation services that are sufficiently exible and extensible to cater for new document formats as they emerge. We present a general model for cross-media annotation services and describe how it was used to de ne an architecture that supports extensibility at the data level as well as within authoring and visualisation tools.
