Cross-Organizational Orchestrator for E-Government Interoperability

摘要

Service Oriented Architectures (SOA) assure better flexibility and increase efficiency by reusing the services to utilize distributed capabilities that may be located in independent trust domains and improve interoperability by providing new opportunities to connect heterogeneous platforms. But it also increases the complexity in the Cross-Organizational Boundaries due to increasing and outsourcing need for e-government organizations to work together and to meet their various customer needs, thus, there is a need for interoperability across organizational boundaries of e-government heterogeneous platforms. A broad range of SOA-platforms is available focusing on Web Service enabling and orchestration that is a key control mechanism that invokes Services to work and to provide control within an organization. This paper addresses a new Cross-Organizational Orchestrator Model that consists of three main components: business services, Cross-Organizational Meta service, and an orchestrator. Then, we are found that our architecture remains cross-organizational e-government interoperability while increases quickness and scalability, bring down the difficulty, improve the utility of advanced extensibility, reliability, flexibility and agility of whole e-government platforms.
