3. Service-based architecture of Access-eGov system Martin Tomášek, Karol Furdík WIKT 2006, 28. - 29. 11. 2006, Bratislava Access-eGov project Full title: Access to e-Government Services Employing Semantic Technologies www.accessegov.org Starting date: January 1st, 2006 Duration: 36 months EC Funding: 1.983.000 € Total Budget: 2.279.243 € Main goal: to develop and validate a platform for composition of government services into complex process definitions (covering life events/business episodes) enabling semantic interoperability of particular e-Government services.

4. Service-based architecture of Access-eGov system Martin Tomášek, Karol Furdík WIKT 2006, 28. - 29. 11. 2006, Bratislava Objectives & Functionality Access-eGov system: a framework / platform for eGov services, based on Semantic Web technologies. Provided services: Meta-service will identify proper eGov services relevant to the given life event or business episode (according to the semantically expressed user‘s needs & requirements), Scenarios consisting of elementary eGov services (of „hybrid“ nature, i.e. a combination of traditional and electronic eGov services), Virtual Personal Assistant - a tool that will guide users in the space of available services.

5. Service-based architecture of Access-eGov system Martin Tomášek, Karol Furdík WIKT 2006, 28. - 29. 11. 2006, Bratislava In Slovakia: land-use planning and processing a request for a building permit. In Poland: establishing an enterprise taking into account the process of company registration. In Germany: an upgrade and field test based on the existing good practice, the so-called “Zustaendigkeitsfinder” ("Responsibility Finder"), by introducing a semantic layer (securing semantic interoperability between national and local governments). In Egypt (German University of Cairo): searching for eGov services provided by an EU country. Use case: applying for a work permit in an EU country. Pilot Applications

7. Service-based architecture of Access-eGov system Martin Tomášek, Karol Furdík WIKT 2006, 28. - 29. 11. 2006, Bratislava Architecture context Security requirements: Privacy (secure personal info), Communication security (data encrytion), Access Control, Trust between nodes. General functional reqs: Reliability (Maturity, Recoverability, Fault tolerance - SoA: components not tightly coupled), Efficiency (caching, effective storage layer). User reqs: eSignature for transactional operations (e. g. invoking services, filling in electronic forms), XML based interface available (including exchange of user information if user permits), Tracing business processes, Retrieval of services / life events, Scenario construction, Personalisation, Multilinguality, etc. Data reqs: Changeability (esp. on Ontology level), Reusability (Knowledge storage is decoupled from other components), Suitability (rich set of knowledge concepts for semantic descriptions).
