A Semantic-based Framework for Virtual Organization Management

Inter-organization collaboration is recently acknowledged as an important vision of the grid research, however there are not many well implemented system and not many applications that are in large-scale real use either. This paper present a VO (virtual organization) ontology model framework that simplifies the Inter-organization collaboration of the future grids. Thanks to the semantic technology, we can develop semantic based model framework to implement interoperability even in heterogeneous environments. The framework, consisted of a bunch of ontologies, definitely defines and describes which attributes of the VOs should define. We define and implement the semantic model of virtual organizations and grid resources and introduce the basic concepts and mechanisms to represent them and apply them to the China Academy of Traditional Chinese Medicine (CATCM). The prototype presented in this paper is also applicable to other VO application projects.
