The Role-based Access Control (RBAC) model provides a way to manage access to information of an organization, while reducing the complexity and cost of security administration in large networked applications. Currently, several design method of Semantic Web (and Web in general) applications was proposed, but none of these methods produces an specialize and integrated model for describing access control policies. The goal of this dissertation is to integrate the access control in design method of Semantic Web applications. More specifically, this work presents an extension of SHDM method (Semantic Hypermedia Design Method) in order to include RBAC model and an rule based policy Model integrated with the other models of this method. SHDM is a model-driven approach to design web applications for the semantic web. A modular software architecture was proposed and implemented in Synth, which is an application development environment according to SHDM method.
