Role-based access control (RBAC) models have been successfully implemented in various information systems in recent years. However, the traditional centralized authorization and administration mechanisms in RBAC have several drawbacks in collaborative environments. In this paper, we propose a distributed domain administration of RBAC model, DARBAC, in which the authorization and administration privileges are distributed to multiple administrative domains. Each administrative role is assigned to an administrative domain and can only execute administrative operations within its domain. By introducing the concept of administrative domain and administrative role hierarchy, the DARBAC model can flexibly meet the access control requirements in collaborative environments. We also describe how to implement the model in the PLM product and how to apply the model in a distributed enterprise environment to support cooperative work
