Abstract
This paper deals with group-oriented discretionary access controls (DAC) in object management systems (OMS). Group-oriented means that subgroup structures which are typical of the organization of design projects are supported. Group paradigms are interpretations of the subgroup structure.
Examples of OMS with group-oriented DAC are CAIS-A and PCTE+. Both support a paradigm which we term the rights package paradigm. In this paradigm, a group corresponds to a set of rights which shall be granted to a group of users.
The goal of this paper is to show that a new paradigm, called the task paradigm, must be supported. Here, a group corresponds to a task which shall be dealt with by a group of users. The main reasons for supporting the task paradigm are access rights required to perform operations with complex objects and requirements of autonomous subgroups.
