Coordinated by Eggo Müller, Professor of Media and communication at the Department of Media and Culture Studies, Utrecht University, the programme will investigate the circulation and appropriation of audiovisual heritage online. Earlier European projects lead by prof. dr. Sonja de Leeuw (UU) and Eggo Müller have provided the infrastructure for archives, collections and libraries to share audiovisual heritage on public platforms such as Euscreen.eu and the European Platform for Digital Heritage Europeana.eu. The new project will look deeper into the divers ways users engage online with audiovisual heritage: What do users watch, share, like, or dislike? What are their comments, what videos are downloaded for remix and recirculation? What new interpretations of heritage materials are created? Do these challenge authorised perspectives on historical events? CADEAH will be the first European project to integrate cutting edge video tracing and tracking technologies as part of a mixed methods approach including textual analysis, virtual ethnography and Digital Humanities methods.
