E-Government Interoperability Framework based on a Real Time Architecture

One of E-Government (E-Gov) implementations is to produce a form of relationship namely Government to Government (G2G). The main factor of G2G concerning interoperability between central and local governments is the heterogeneity in developing E-Gov applications. The interoperability that has occurred are done by creating a brand new architecture that has a function to allow existing E-Gov applications to be able to communicate with each other. E-Govs in Indonesia are developed separately by the respective governments, i.e. central (national) and local (province, district/city). Therefore, interoperability and data integration have such a restriction. This paper focused on creating an Enterprise Architecture Framework (EAF) for interoperability and data integration on EGov applications in Indonesia. This EAF combines the approach of Service Oriented Architecture (SOA) and Event Driven Architecture (EDA). The purpose of this combination is to produce EAF that is real-time, the relationship between the oneto-many services, and the message transmission models that are asynchronous. The services provided and the events that are used to trigger are defined by using Web Service Definition Language (WSDL), while the orchestration mechanism that occurs between services is defined by using the Business Process Execution Language (BPEL). BPEL is conducted by the Government Service Bus (GSB). To evaluate this EAF, the model of services which has been defined using a variety of data is measured based on execusion time.
