A computer utility is envisioned as a large, multi-access computer system providing its users with the ability to store information and share its use with other system users. This thesis considers the nature of information sharing and how a computer utility can provide facilities allowing such sharing to take place in a controlled manner. From a discussion of the goals of a computer utility, a set of requirements for the facilities of the utility is described. A model is developed which presents a method for structuring information. It is shown that the mechanisms of the model preserve certain structural characteristics of the information, and that these properties can be directly related to the requirements regarding the control of shared information. Extensions of the basic model are described which allow more selective types of control and which remove some of the limitations of the basic model. Author
