....network and systems management progresses, it becomes increasingly important to clarify what we mean by management policies. A first step towards this was the definition of the term policy. However, this only allows to distinguish whether a statement is considered to be a policy or not ( MOSL 91] The vast number of policies, some examples of which we will present later, calls for a classification i.e. a well defined set of (orthogonal) grouping criteria. The goals of such a classification of policies are listed below: 1. to find commonalities of and similarities between different ....

....Static enumeration of objects at some point in the past is not usually what is required in evaluation of policies, and domain expressions in a policy such as an access rule are evaluated at the time the rule is checked. 4 POLICIES We have recently presented a generic user view of policies [Moffett 1991] which identifies their essential characteristics and models them as objects with the following attributes: subjects who are motivated or authorised, depending on the mode of the policy, to achieve goals on target objects . An access rule is an example of this generic policy object. The user ....

....by a human or by a sophisticated program without time constraints. This is due to the complexity of the policy concept (not yet formally specified) The research community is only now beginning to address the issue of how to specify management policy. For example, in the Domino project ( 13] [14]) management policies are implemented as system objects, but limited to access rules. The Pythagoras project (cf. 15] is also concerned with modelling policies in order to create a database of the policies of an organization. A policy in pythagoras is a right or a responsibility declared so as ....

....[87] The problem of rendezvous: how do collaborators initially come together [77] Applications must deal with issues related to control over the environment. How do users specify their desires about how the system should behave in relation to other users who are potential collaborators [67] Many of the issues above are at odds with one another. For example the need for privacy must be weighed against the potential benefits of awareness. Problems such as these are largely the domain of sociologists, psychologists, and interface designers. The builders of computer software typically ....

....principle or plan that guides the actions taken by a person or group [2] In a collaborative environment, policies govern the particulars of how users and applications interact with one another. A policy describes a general contingency against which specific events are evaluated and handled [67]. The goal of a policy system should be two fold: Reduce unpredictability in the system. Allow the system to respond in expected ways to the actions of users and other applications, and support the principle of least surprise. Require less effort from users. Move the burden of dealing with ....

This paper presents a system that allows users to control collaboration by enacting policies that serve as general guidelines to restrict and ....

....target objects within a domain to which the policy will be applied (see section 3.4 below) 3. 3 Policy as Relationship Objects Policies encapsulate a representation of information affecting component behaviour so we treat them as objects which provide operations for querying or changing policies [10]. A policy service then provides the operations for creating, deleting, storing and retrieving policy objects. Policy scope is specified using domains, so the policy service must also provide the ability to identify what policies apply to a domain and then use the domain service to identify the ....

....viewed from above it is a plan, and viewed from below it is an objective. This paper is the third in a series which proposes a model for the representation of management polices in distributed systems and explores how the model may be applied to some main concerns in making policies. The first (Moffett Sloman 1991b) proposed the model and suggested a number of research avenues. The second (Moffett 1993) set out specifically to explore how policy conflicts could be analysed and resolved within the model. The current paper is a discussion paper which aims to explore the refinement of high level policies into ....

Policy Representation We briefly summarise the generic characteristics of a management action policy which we represent as an object which can be manipulated by performing operations on it.
