Identify the inadequacies of current trust models and design a model for the semantic web/DIVO=Components include trust management, trust negotiation as well as economic tradeoffs0Design a Language for specifying Trust policies-Start with XML, RDF and Web Rules language and incorporate features for trust management and negotiation 0Design and develop techniques for
