Realizing Interoperable Infrastructure for Electronic Business Systems and Local Government Systems

Web Services and related open standard technologies are key technologies for system infrastructure in industry systems and local government systems. There are many projects that have adopted these technologies in the local government systems and also in B2B systems in various industries. We found that one of the key requirements to promote these standards in industries is pull messaging for client/server systems, since many small and medium enterprises can't afford server systems. To achieve this, we have standardized Pull messaging specification as a part of ebXML (Electronic Business using eXtensible Markup Language) Messaging Services Specification Version3.0, with inputs of industries requirements. We also have developed Conformance test tool and additional test assertions for ebMS3.0 to promote interoperable implementation for ebMS3.0, and executed interoperability test. In this experience, we have found interoperability issues in open source. We will investigate this issue further, and continue giving feedbacks to implementations and prototype. We believe this experience regarding Pull messaging technology will be valuable for local government systems in the future, when it is going to expand its infrastructure to connect with medium and small entities.
