Weak Signal's description 
The goal of the NoE (Network of Excellence) PetaMedia is to bring together the research of four national networks in the Netherlands, Switzerland, UK and Germany in the area of multimedia content analysis (MCA) and social peer-to-peer networks and eventually to establish a European virtual centre of excellence. The collective research that will integrate the four national networks will be directed towards the synergetic combination of user-based collaborative tagging, peer-to-peer networks and multimedia content analysis, and towards identification and exploration of potentials and limitations of combined tagging, MCA and SP2P concepts. Solutions and collaborative research field trials will be build on the coordinating partner's open source P2P software Tribler.
