Abstract. In this paper we propose a formal model which supports the process of setting up a Virtual Organization by means of allowing contract negotiation between parties pariticipating in such VO. The negotiated contract is used to configure the necessary Grid middleware components for the purpose of contract enforcement during the lifetime of the Virtual Organization. We present a brief overview of the framework and discuss in detail the formal model underlying the process of contract negotiation and how the ontological description of the domains related to given VO supports this process.

Abstract. As modern SOA and Grid infrastructures are being moved from academic and research environments to more challenging business and commercial applications, such issue as control of resource sharing become of crucial importance. In order to manage and share resources within distributed environments the idea of Virtual Organizations (VO) emerged, which enables sharing only subsets of resources among partners of such a VO within potentially larger settings. This paper describes the Framework for Intelligent Virtual Organizations (FiVO), focusing on its functionality of enforcing security (Authentication and Authorization) in dynamically deployed Virtual Organizations. The paper presents the overall architecture of the framework along with different security settings which FiVO can support within one Virtual Organization.

This paper presents a brief overview of the work on translation of Common Information Model (CIM) to Web Ontology Language (OWL) standard. The main motivation for the work is given, along with discussion of major issues faced during this work. The paper contains also comparison of existing approaches to conversion of CIM to OWL and presents the CIM2OWL tool that performs the conversion of CIM schema and allows convertion of CIM instances-representing for instance configurations of particular systems-to OWL individuals.
