The need for centralized e-Government strategies and policies is a fertile ground for the development of e-Government INTEROPERABILITY FRAMEWORKS (eGIFs). Integrated information systems and one-stop public services to citizens and businesses are heavily dependent on the resolution of the ever-expanding interoperability challenge and the satisfaction of public services' stakeholders. This can only be realistically addressed if the scope of eGIFs is widened, to include service composition and discovery, security standards, certification of public sites, as well as unified data models for achieving a common understanding of semantics at a syntax-independent level. The Greek eGIF presents a transition from paper-based specifications to a robust system that acts as a repository of systems, services, data schemas, certification tools and training material. This paper presents the objectives, the overall methodology and the architecture of the Greek eGIF, that meets today's demands for modelling, storing, managing and updating a vast number of eGovernment-related information.

There is a growing need for better project management in e-Government endeavors to bring together people with diverse knowledge and skills so they can develop and implement project activities effectively and efficiently. This paper is a research report on eGTPM (e-Government Transformation Project Management) platform, a project management tool which assists implementers and decision-makers in e-Government project planning and control. eGTPM Platform improves most existing commercial tools by integrating goal orientation and dynamic enterprise modeling (DEM) principles into the knowledge building tool developed at the Decision Systems Laboratory in National Technical University of Athens. By employing goal orientation and DEM principles' concepts, eGTPM facilitates communication and collaboration among all involved parties in order to jointly identify project needs and requirements and to reduce the number of changes due to misunderstandings. eGTPM also includes a knowledge based project control advisor which contains heuristic knowledge to guide users to possible design alternatives. The paper describes eGTPM's components and possible directions for future work.

Technological advances have highly facilitated the accession of health-related information. As the public search on hospital websites for information and services is increasing, hospitals need to upgrade their websites to meet the high standards and demands of health-care consumers. Today, many hospital websites use a patient-centric approach to promote engagement and encourage interaction for better health-related decision making. However, little is known about the current state of hospital websites in Portugal. This study aims to assess hospital websites in Portugal and offer improvement insights. In this paper, the websites of 132 selected hospitals were thoroughly examined and assessed according to a predefined list of indicators and sub indicators, based on four criteria: technology, content, services and community interaction, defined in the Health Sector Website Assessment Index (HSWAI) instrument. Most of the websites scored satisfactorily in the technology criterion, performed fairly well in providing fundamental content, but showed shortcomings in quality metrics data and online patient services, and most of them fell short in community interaction elements. Overall, the results show that each hospital website must be improved in specific features in order to become effective and efficient. Several of the identified assessment elements (indicators/sub indicators) fall under Sustainable Development Goal (SDG) 3, United Nations health-focused goal, and could be used by governments to assess their progress toward achieving that specific goal. Therefore, this study not only provides a comprehensive and systematic approach that quantitatively measures hospital websites' overall performance, but also contributes to practical applications in terms of worthwhile recommendations for a website that meets patient's demands and hospital's operational needs.
