Abstract. The present emergence of loosely-coupled, inter-enterprise collaboration, i.e., virtual organizations calls for new kind of middleware: generic, common facilities for managing contract-governed collaborations and the autonomous business services between which those collaborations are formed. While further work is still needed on the functional governance of the collaborations and services, even more work is awaiting on the management of non-functional aspects of the virtual enterprises and their members. In this paper, languages and architectures for service level agreement between Web Services are discussed and the maturity of the service level management solutions is reflected against the needs of federated virtual organizations.

“…Policies can use events disseminated by the monitoring system to synchronize their activities, but this is a low-level and difficult means of specifying coordination and synchronization between roles so there is a need for a higher level notation for the specification of concurrency constraints (see section 5). For other studies relating to inter role relationships and possibilities for their graphical representation see [20][21][22][23].…”

Roles have been widely used for modeling the authority, responsibility, functions and interactions associated with manager positions within organizations. In this paper we discuss the issues related to specifying roles for both human and automated managers of distributed computer systems. The starting point is that a role can be defined in terms of the authorization and obligation policies, for a particular manager position, which specify what actions the manager is permitted or is obliged to do on a set of target objects. This permits individuals to be assigned or removed from positions without respecifying the policies for the role. However these policies are insufficient for fully specifying relationships between managers and the targets they manage or between different manager roles. There is a need to specify the interaction protocols and how managers coordinate and synchronize their activities.The role based framework consists of a set of tools enabling the creation of roles from policies, the specification of the concurrency constraints for role activities and the specification of protocols for role interaction. In addition, the issues related to conflicts which can occur between policies within a role or between interacting roles are briefly discussed.

“…Frequently used contracts may evolve a common form and become a standard contract or a contract template [9,81. The template's pre-agreed format and content (in the form of fields) can easily be specified in a formal manner and therefore templates are ideal candidates for automated match-making.…”

This paper deals with the automation of parts of the process of setting up inter-organisational eo-operaticns by electronic means. The paper presents a high-level model of the life-cycle of a co-operation between autonomous organisations. Contracts and their possible computer representatioris are investigated with a view towards implementing the contractual match-making and contractual binding stages of the life-cycle in a dynamic and rapid fashion. The mechanisms and processes which are necessary $ these stages are to be automated are then described. Extensions to the ODPKORBA Trading Servicc are shown to be necessary if trading is to be used in automating contractual match-making and binding. These extensions are described and it is shown how they con be exploited together with interception techniques f o r setting up the link between the co-operating organisations. 'These techniques can also be used to provide a rani;e of decision-making and resource-allocation options concerning the co-operation set-up.
