Abstract:The Dutch government has defined an agenda to enforce interoperability in public services by means of Information and Communication Technology (ICT). Three dimensions of interoperability can be distinguished: the organizational, semantic and technical one. These dimensions pose specific requirements on candidate solutions. Additionally, integration projects are accompanied by a number of common requirements which should be addressed by a potential solution as well. Dutch municipalities are slowly evolving towards a mature level of Electronic Service Delivery (ESD). Unfortunately, a vast collection of differing systems, policies, adopted standards, and social aspects are typically involved. This disparate situation within and between these municipalities slows the process towards sophisticated electronic government down. Enterprise architecture can be used to provide insight in the structures, relations, information flows and products in an organization. We have adopted an enterprise architecture framework which covers a municipality and the required interoperability by means of seven domains. By using these domains in combination with views to focus on relevant information, this information can be targeted at specific stakeholders. The business, application, and technology views have been used in this research. These views correspond with the layers of abstraction used in the adopted enterprise architecture framework. The techniques discussed in this research have been positioned in the enterprise architecture framework by relating it to a certain domain. We use the technologies’ description and position in the framework to predict their influence on surrounding domains. The Service-Oriented Architecture (SOA) is an application architecture which follows the Service-Oriented Computing (SOC) paradigm and can be positioned in the application domain of the enterprise architecture framework. This architecture is expected to provide the interoperability as required by the Dutch government. It describes a design, development and deployment approach for information systems, by defining concepts and general techniques for designing, encapsulating, and invoking reusable business functions through loosely bound service interactions. SOA can operate platform, time and location independently. Therefore this approach enables the development of highly distributed cross-organizational systems.
