National Interoperability Frameworks: The Way Forward
Abstract: National Interoperability Frameworks (NIFs) have been ...more
established during the last years as the governmental policy cornerstones for deploying joined-up information systems and providing one-stop services to citizens and businesses all over the world. In order to meet the rising expectations of their stakeholders, to cope with technological evolutions in the future internet era, and to achieve efficient resolution of the evolving interoperability problems, NIF’s developers face new challenges: The scope of the frameworks needs to be extended, including service composition and discovery, development and management of semantic elements, certification mechanisms and authentication standards. Moreover, a shift from a paper-based specification towards a repository of services, data schemas, process models and standards is needed, in order to serve the ever-changing requirements of governments under transformation. Going beyond an analysis of relevant frameworks at an international level, this chapter illustrates the best practices and the future directions for NIF’s, proposing an infrastructure that can meet the demands for modelling, storing, managing and transforming vast numbers of service descriptions, XML hierarchies, as well as specific technical, semantic, organisational and legal interoperability standards.

Achieving Interoperability through Base Registries for Governmental Services and Documents Management
Abstract: As digital infrastructures increase their presence ...more
worldwide, following the efforts of Governments to provide citizens and businesses with high quality one-stop services, there is a growing need for the systematic management of those newly defined and constantly transforming processes and electronic documents. eGovernment Interoperability Frameworks usually cater for the technical standards of eGovernment systems interconnection, but do not address service composition and use by citizens, businesses or other administrations. An Interoperability Registry is a system devoted to the formal description, composition and publishing of traditional or electronic services, together with the relevant document and process descriptions in an integrated schema. Through such a repository, the discovery of services by users or systems can be automated, resulting in an important tool for managing eGovernment transformation towards achieving interoperability. The chapter goes beyond the methodology and tools used for developing such a system for the Greek Government, to population with services and documents, application and extraction of useful conclusions for electronic Government transformation at global level.

Investigating the Landscape in National Interoperability Frameworks
Abstract: Openness, accountability, and transparency have attracted ...more
researchers’ and practitioners’ interest as open data and citizen engagement initiatives try to capitalize the wisdom of crowds for better governance, policy making, or even service provision. In this context, interoperability between public organizations, citizens, and enterprises seems to remain the center of interest in the public sector and national interoperability frameworks are continually revised and expanded across the globe in an effort to support the increasing need for seamless exchange of information. This paper outlines the current landscape in eGovernment interoperability, analyzing and comparing frameworks that have reached a certain degree of maturity. Their strengths and weaknesses at conceptual and implementation level are discussed together with directions for reaching consensus and aligning interoperability guidelines at a country and cross-country level.

Transforming Traditional Production System Transactions to Interoperable eBusiness-aware Systems with the use of Generic Process Models
Abstract: Through the years, successful enterprises have been ...more
identified as the ones that were able to adapt their processes and ways of conducting business to the needs of their environment and the technological achievements of their times. This statement has not changed during recent years, but today, due to the major breakthrough of the internet and the possibilities it offers for a unified electronic marketplace, enterprises have to take advantage of the new technological tools offered, in order not only to adapt to this new emerging environment, but also to benefit from it and expand their operations in parallel with minimising costs. Achieving interoperability of the various production systems, and not only enabling hard-wired connectivity, seems to be the key that will unlock the gates leading to this newly established global market, and therefore enterprises need to focus more on their already established processes in order to be able to formulate a global standard for executing business transactions and cooperating smoothly with each other.

Emerging Interoperability Directions in Electronic Government
Abstract: Being important at organizational, process and semantic ...more
levels, interoperability became a key characteristic of the new electronic government systems and services, over the last decade. As a crucial prerequisite for automated process execution leading to “one-stop” e-Government services, interoperability has been systematically prescribed, since the dawn of the 21st century: Standardization frameworks, that included guidelines ranging from simple statements to well defined international Web-Service standards started to appear at National and Cross-Country levels, powered by governments, the European Union or the United Nations. In parallel, most international software, hardware and service vendors created their own strategies for achieving the goal of open, collaborative, loosely coupled systems and components. The paper presents the main milestones in this quest that shaped electronic government during the last years, describing National Frameworks, key Pan- European projects, international standardization and main industrial and research achievements in the EU. Moreover, the paper describes the next steps needed to promote interoperability at technical, semantic, organizational, legal or policy level – leading to the transformation of administrative processes and the provision of low-cost, high-quality services to citizens and businesses.

Defining a Taxonomy for Research Areas on ICT for Governance and Policy Modelling
Abstract: As governments across the world provide more and more ...more
support to open data initiatives and web 2.0 channels for engaging citizens, researchers orient themselves towards future internet, wisdom of crowds and virtual world experiments. In this context, the domain of ICT for Governance and Policy Modelling has recently emerged to achieve better, participative, evidence-based and timely governance. This paper presents a taxonomy classifying the research themes, the research areas and the research sub-areas that challenge this domain in order to deal with its diversity and complexity. Taking into account advancements in research, policy and practice, the taxonomy brings together the open, linked data and visual analytics philosophy; the social media buzz taming collective wisdom in decision-making; and the future internet approaches around cloud computing, internet of things and internet of services, while embracing the collaborative policy modelling aspects and the safeguarding against misuse implications.

Towards a Scientific Approach to e-Government Research
Abstract: E-Government has an unprecedented potential to improve ...more
the responsiveness of governments to the needs of citizens and has long been recognized as a key strategic tool to enable reforms in the public sector. However, this potential is to this day non-systematically exploited, as e-government research efforts are largely uncoordinated and there are significant barriers that hinder the effective exploration, management and distribution of the vast amounts of public sector information towards the research communities, and a lack of proper tools to allow their utilization and computation by the latter. In this context, the main goal of this paper is to review the current status of research and broader activity in the field of e-Government, identify the challenges that the e-government research and practice communities face and address the latter in terms of introducing a new scientific approach to e-government research, based on the deployment and use of a virtual research-oriented service infrastructure that will make available and enable to process large amounts of available knowledge within the public sector, internationally. For this aim, the paper presents the conceptual framework related to this approach, describes the model architecture of the envisaged infrastructure and determines a set of requirements and practical implications that need to be taken into account to ensure its success.

Implementing Federated Interoperability Infrastructures: Issues and Challenges from the Citizens Base Registry in Greece
Abstract: As the need for interoperability infrastructures and ...more
services is more and more stressed by researchers and practitioners in e-Government, Base Registries, as fully electronic, centralized repositories of information for classes of entities, pose as an infrastructure that can support aggregate electronic services delivery. In the presented approach, a Base Registry storing the citizen records is designed to integrate the legacy databases of 1,034 municipalities and is opened up to support the provision of electronic services towards governmental organizations. Discussion on the results is targeting at best practice examples that can be drawn at scientific and organizational level, but also at the key difficulties that have to be tackled in such public sector information reuse approaches – in relevance with the administrations and industry readiness in each country, in order to fulfill one of the principal conditions for pan-European Public Services.

Business to Business Interoperability: A Current Review of XML Data Integration Standards, Computer Standards & Interfaces
Abstract: Despite the dawn of the XML era, semantic interoperability ...more
issues still remain unsolved. As various initiatives trying to address how the underlying business information should be modelled, named and structured are being realised throughout the world, the importance of moving towards a holistic approach in eBusiness magnifies. In this paper, an attempt to clarify between the standards prevailing in the area is performed and the XML Data Standards providing generic XML Schemas are presented. Based on this “XML Data Standards Map”, a multi-faceted classification mechanism is proposed, leading to an extensible taxonomy of standards. A set of facets is analyzed for each standard, allowing for their classification based on their scope, completeness, compatibility with other standards, openness, ability to modify the schemas and maturity, to name a few. Through populating and querying this multi-faceted classification, a common understanding of Data Integration Standards can be ensured and the choice of a standard according to the requirements of each business can be systematically addressed.

Unified Data Modeling and Document Standardization Using Core Components Technical Specification for Electronic Government Applications
Abstract: In the effort of Governments worldwide to effectively ...more
transform manual into electronic services, semantic interoperability issues pose as a key challenge: system-to-system interaction asks for standardized data definitions, codification of existing unstructured information and a framework for managing governmental data in a unified way. Integrating and extending recent developments in Germany, Hong-Kong, UK and US governments - but also eBusiness interoperability research results in Europe, the proposed approach is applied within the Greek e-Government Framework and bears the following steps: (a) Gathering and analysis of governmental service forms at field level, so that common structures can be identified, (b) Customization of UN/CEFACT Core Components, (c) Semiautomatic XML Schema Definition (XSD) files creation, using sets of naming, structuring and verification rules, (d) Adoption of international or development of country-specific Codelists, (e) Development of guidance material for the application of the approach by government officials at central or local level. Discussion on the results is targeting best practice examples that can be drawn at scientific and organizational level, but also the key difficulties that have to be tackled – in relevance with the administrations and industry readiness in each country. Future steps include enhancing the paradigm in order to cover vertical data standards and applying the approach to other EU or associated countries.

A Core Component-based Modelling Approach for Achieving e-Business Semantics Interoperability
Abstract: The adoption of advanced integration technologies that ...more
enable private and public organizations to seamlessly execute their business transactions electronically is still relatively low, especially among governmental bodies and Small and Medium-sized Enterprises (SMEs). Current solutions often lack a common understanding of the underlying business document semantics and most existing approaches are not able to cope with the huge variety of business document formats, stemming from highly diverse requirements of the different stakeholders. Developed and applied in the course of the EU-funded research project GENESIS, this paper presents a comprehensive core component-based business document modelling approach that builds upon existing standards such as the OASIS Universal Business Language (UBL) and the UN/CEFACT Core Component Technical Specification (CCTS). These standards are extended by introducing the concept of generic business document templates out of which specific documents can be derived according to the actual user’s needs. Key principle to achieve this flexibility is the integration of business context information that allows for modeling standard-based but at the same time customized business documents. The resulting modelling framework ranges from (tool-supported) graphical data models to the technical representation of the business documents as XML schema documents designed in compliance with the UN/CEFACT XML schema Naming and Design Rules (NDR).

Achieving Cross-Country Electronic Documents Interoperability with the help of a CCTS-based Modeling Framework
Abstract: The dawn of the XML era appears insufficient to guarantee ...more
a holistic approach in electronic transactions, as long as the semantics confusion, the lack of a common understanding of the underlying data and the business standards dilemma prevail and prevent data interoperability issues from being resolved. As various e-Government initiatives are being realized throughout the world, an imperative need for creating unified governmental data models that will facilitate the seamless exchange of information and the deployment of interoperable systems in Enterprises and Central, Regional and Municipal Government emerges. After attempting to identify relevant research that has been undertaken in the field of data modeling, the present paper analyzes the scope and the objectives of the business information modeling oriented towards governmental data. Based on UBL (Universal Business Language) and CCTS (Core Components Technical Specification), a component-based data modeling methodology enhancing business-to-government interoperability is proposed, creating the basis for a repository of governmental data models. The approach adopted may also serve as guidelines for creating and transitioning between "generic - harmonized" and "specific - contextualized" documents. A real world paradigm extracted from the Periodic VAT Statement document finally comes to prove the soundness of the proposed methodology.
