Abstract

AbstractCross-Organizational interoperability and coordination are core issues to Virtual Organization (VO) researches. We propose a model of VOs in which VO related concepts are modeled in an extension of the OWL-S service ontology and SWOCRL (Semantic Web Object Constraint Rule Language) rules. Within this framework, VO abilities can be seen as services provided; coordination between VOs can be seen as service invocation. SWOCRL rules are used as mediators between service descriptions and requests. A prototype system of our framework is proposed combining Constraint Handling Rules (CHR) and Prolog.KeywordsVirtual OrganizationOWL-SSWOCRLSupply Chain for Agricultural Product
