IDENTIFY PUBLIC SERVICES AND SOFTWARE ORIENTED ARCHITECTURE SERVICES TAXONOMY

Abstract

In order to identify the building blocks which make up public services for citizens and businesses, it is imperative to establish a common approach in terms of definitions and the categorisation of services (a service taxonomy) and a methodology to identify the different services which are part of the process of delivering an entire service to the end user (a service decomposition methodology). This paper describes the approach taken in this study, which comprises a review of existing Software Oriented Architecture (SOA) literature on service categorisations and SOA-related literature on methodologies to decompose a service process into different service components. The service taxonomy and the service decomposition methodology proposed allows for the identification and categorisation of services based on existing processes in the delivery of government services in three Member States. This first step also facilitates an evaluation of the possibilities for the design of a 'cloud of public services' and the potential impacts of reuse within government or by third parties.
