Ontological model of event for integration of inter-organization applications

Inter-organization event handling process includes two levels' business processes: global business processes need multiple businesses of different organizations to work coordinately; local business processes are multiple activities contained in each business process. All these business applications are running in heterogeneous environments of different locates. How to describe business processes of different levels in event handling entirely, and have transactions and heterogeneous information from different organizations united semantically to satisfy requirements of different users, are the keys to successful event handling. This paper brings forward iEM based on the features of inter-organization integration as well as the multi-level and multi-facet characters in its event disposition. iEM provides stratified modeling of inter-organization integration events, accomplishes common expression of events among multiple domains, and gives common terminology for inter-domain information exchange. It can depict basic processes of events in detail by expression of events in multiple granularities and relationship specialization in the same granularity to meet different user groups' need. At last, Application of JERS (Joint Emergency Response System) using iEM is presented.
