ABSTRACT Many real-life organizations are hierarchies of largely autonomous, heterogeneous members (individuals or other organizations), often exhibiting rich policies. We restrict our attention to organizations that monitor their environment, collate events, determine compliance of their behaviors with their policies, and potentially act in anticipation of events to ensure the satisfaction of their policies. This paper models cross-organizational service agreements as resulting in the formation of organizations. This paper emphasizes the importance of proactive policy-based governance in organizations (modeled as multiagent systems) and provides a novel architecture supporting policy monitoring, governance, and enactment. This paper provides an initial formalization and discusses the compliance and completeness of behaviors produced from specified policies. To demonstrate the practical utility of this approach, it is implemented using an existing policy engine and messaging middleware.

    ABSTRACT: We address the problem of usage license administration in federated settings. This problem arises whenever organizations, such as educational or research groups or institutions, share resources for business and scientific reasons. In such settings, each user's usage of a licensed resource is typically supported by the user's organization. License administration involves satisfying legal requirements while applying organizational strategies for effective resource usage, and carrying out suitable accounting and audit controls. We propose an approach, Licit, wherein an agent represents each resource sharing site and administers licenses in collaboration with other agents. We show how to represent a variety of usage licenses formally as executable policies and provide a simple information model using which each party can specify both the attributes involved in its licenses and how to resolve them. Our architecture naturally accommodates a variety of site-specific (i.e., custom) strategies for license administration. Licit has been implemented in a popular open source framework for virtual computing, and yields performance results indicating its practical feasibility.

    ABSTRACT: A service engagement brings together two or more par- ties in a contractual arrangement. This paper considers a commitments-based approach for modeling and enact- ing service engagements. We model a service engagement as arising within a dynamic service organization or Org. The members of an Org create commitments toward each other. The proposed approach places Orgs within insti- tutions, themselves modeled as specialized Orgs that pro- vide a social or legal environment for service engagements. Commitments form the basis of the interactions among the participants of an Org. This paper provides an agent-based conceptual model for Orgs and addresses the dynamic as- pects of the enactment of service engagements.

    ABSTRACT: Economic theory defines business services as customisable, interactive processes that providers have the potential to carry out together with clients that benefit from the effects. It is understood that business service transactions are best organised by means of virtual networks, where information technology allows for configuring multiple providers and processes on a per-request basis. Existing conceptual models for virtual service enterprises propose business service virtualisation to allow for flexible and agile regulation and control of coordination between multiple providers and clients. In this paper, we present an approach for realising business service virtu-alisation based on software service technology. In particular, we propose a service-oriented software architecture for representing virtual business service processes as e-services. E-service models specify flexible business service interactions between multiple providers and clients of virtual service enter-prises and allow for regulation and enforcement of their coordination. We demonstrate the utilisation of our e-service SOA in the context of an e-science scenario, where we show how to design e-service models for the use case of virtual polymorph prediction laboratories.
