Building a Local Administration Services Portal for Citizens and Businesses: Service Composition, Architecture and Back-Office Interoperability Issues

摘要

Two of the most active research fields in information technology nowadays are Internet Services Portals used by governmental organizations and Interoperability Patterns for achieving the seamless cooperation of heterogeneous existing systems. When referring to e-Government applications in Local Administrations, the above mentioned research fields have to be tackled, as the resulting systems need to be functional, easy to implement and maintain, capable of interconnecting with back-office systems and citizen and employee friendly. This paper shows that the conceptualization, design, implementation and maintenance of Municipality Service Portals can be standardized, following a specific methodology. Piloted in a Greek Municipality with almost 50,000 citizens and 3,000 businesses, the methodology comprises of (a) rapid process modeling with the use of BPMN-aware modeling tools, (b) CCTS-based data modeling ? step-by-step adaptation of Content Management, Citizen Relationship and Workflow Systems, (d) SoA-enabled interconnections with back-office applications and (e) overall guidance based on Service Composition taxonomies.
