Abstract
Many Web portals allow users to associate additional information with existing multimedia resources such as images audio and video However these portals are usually closed systems and usergenerated annotations are almost always kept locked up and remain inaccessible to the Web of Data We believe that an important step to take is the integration of multimedia annotations and the Linked Data principles We present the current state of the Open Annotation Model explain our design rationale and describe how the model can represent user annotations on multimedia Web resources Applying this model in Web portals and devices which support user annotations should allow clients to easily publish and consume thus exchange annotations on multimedia Web resources via common Web standardsThe work has partly been supported by the European Commission as part of the eContentplus program EuropeanaConnect and by a Marie Curie International Outgoing Fellowship within the 7th Europeana Community Framework Program The development of OAC is funded by the Andrew W Mellon foundation
