A Conceptual Modeling Approach to Virtual Organizations in the Grid

Abstract

One of the key problems with virtual organizations in the context of the (Semantic) Grid is we don’t know how to describe the components used in virtual organizations because they appear to be dynamic, dispersed, transient, type-vague (or we don’t know their types), heterogeneous, semantically informal, and disorderly. The existing semantic modeling approaches lack effective modeling facilities for modeling virtual organization components. Our observations were suggesting focusing on the following aspects: First, we should model both static resources and dynamic states of a virtual organization. Second, we should build up the virtual organizations with abundant static resource. Third, we should combine the semantic modeling with the users’ requirements description for virtual organizations due to its importance. In this paper, we analyze the current situation of the virtual organization research and propose our experimental semantic description model for virtual organizations. We also present the design architecture for the Realcourse application.
