2. Motivation eGovernment resources metadata: an important ingredient to achieve standardised service description, retrieval, composition and cross-organisational collaboration Existing schemas (e.g. UK eGovernment Metadata Schema, based on Dublin Core) present certain shortcomings: Are designed for generic resource description (do not cover the depth and width of the domain) Do not contain or propose value codification (standard codelists) Pan-European standardisation of service metadata is essential for the new Services Directive. Metadata sets form parts in larger eGovernment Ontologies, with applications in public knowledge management and semantic interoperability

3. The Context: The Greek eGIF Co-ordination Strategy (Vision and Strategy for Interoperability & e-Government, Goals & Metrics, Maturity Matrix & Roadmap for PA) Enterprise Architecture / Organizational Interoperability(Guidelines for Service Documentation, Business Process Alignment & Re-engineering , Legal Issues) Services & Processes Repository XML Schemas & Core Components Repository Information Architecture/ Semantic Interoperability (Guidelines for XML, Standard Schemas, Codelists, Development Tools) Co-ordination Activities (Marketing & Comm. Plan, Co-ordination & Acceptance Mechanisms) Need for describing resources in a systematic way: eGMS+ Computational Architecture / Technical Interoperability (System & Components Topology, Design guidelines) Web Services Repository & UDDI Training Activities (Skills Management, Training Process, Training Material) Systems Reference Repository Web Portals & Multi-channel Access Specifications (Accessibility, Ergonomics, Structure, GCL) Technical Interoperability Specifications (Communication, WS stack, storage standards, vertical standards) Authentication & Security Specifications (eID, Trust levels, authentication mechanisms, encryption) Access & Collaboration Tools Maintenance Processes (Update, Change Management, Versioning Processes) Certification Tools Certification Framework (For organisations, systems, data and people) “Standards & Specifications” Level “Coordination” Level “Systems” Level

4. The Context: Service Registries in eGovernment Need for describing resources in a systematic way: eGMS+

17. Conclusions – Future Work Standardization of an ontology-based extended metadata set embracing the e-Government knowledge, from services and documents to code lists and information systems, which: Effectively supports the Greek e-Government Interoperability Framework and the Interoperability Registry Prototype implementation. Formalizes the exchange of information between portals and registries. Includes metadata around service delivery scenarios that can guide any business process re-engineering effort in the public sector. Future steps include exploration of how such a metadata set can: (a) embrace policy modelling and intelligent governmental service front-ends (b) be further elicited in order to take into account citizens’ feedback when designing public services.
