Abstract

GOLD (Grid-based Information Models to Support the Rapid Innovation of New High Value-Added Chemicals) is concerned with the dynamic formation and management of virtual organisations in order to exploit market opportunities. The project aims to deliver the enabling technology to support the creation, operation and successful dissolution of such virtual organisations. A set of middleware technologies are designed and being implemented to address issues such as trust, security, contract management and monitoring, information management, etc. for virtual collaboration between companies. In this paper we discuss the set of requirements for access control in dynamic virtual organisations that have been defined as part of the trust-related work. We propose a solution, which extends the ideas of role based access control (RBAC), and we examine the use of existing and emerging Web Services technologies as an implementation platform.
