A Goal-Driven Management Framework for Electronic Government Transformation Projects
Abstract: As the implementation of e-Government projects is becoming increasingly important in both public and ...more
private organizations, the need to successfully tackle project management emerges. Without a project management framework, those who commission an e-government project, those who manage it and also those who work on it will not have the necessary tools to plan, organize, monitor and re-schedule tasks, responsibilities and milestones. The present paper outlines a goal-driven and knowledge-based framework to plan and manage the critical aspects of e-government projects. A specifically designed tool supports the framework application and a lighthouse project of the Greek public sector is presented to illustrate the application context, leading to reusable conclusions on achievements and problems faced.

Why do eGovernment Projects Fail: Risk Factors in Information Systems Projects of the Greek Public Sector – An International Comparison
Abstract: This paper presents an empirical study of the risk factors of large governmental information systems (IS) projects....more
. For this purpose the Official Decisions of the Greek Government Information Technology Projects Advisory Committee (ITPAC) concerning 80 large IS projects have been analyzed and interviews with its members have been conducted. From this analysis 21 risk factors have been identified, and further elaborated and associated with inherent particular characteristics of the public sector, extending existing approaches in the literature. A categorization of them with respect to origin revealed that they are associated with the management, the processes, and the content of these projects. Results show that behind the identified risk factors there are political factors, which are associated with intra-organizational and inter-organizational politics and competition, and can be regarded as ‘second level’ risk sources. The risk factors identified in this study are compared with the ones found by similar studies conducted in Hong Kong, Finland, and the United States, and also with the ones mentioned by OECD reports. Similarities and differences are discussed.

Measuring e- Business and e-Government Interoperability in South Eastern Europe and the Mediterranean: The Interoperability Observatory
Abstract: This paper introduces the Interoperability Observatory, a structured research effort for measuring interoperability ...more
readiness in the regions of South Eastern Europe and the Mediterranean, supported by the Greek Interoperability Centre. The motivation for this effort derives from the fact that, although interoperability is a key element for public administration and enterprises effective operation, and an important enabler for cross-country cooperation, a standard framework for benchmarking interoperability developments at country level is currently not in place. Interoperability-related information is highly fragmented in different ICT, e-Government and e-Business reports. In this context, in the core of the Interoperability Observatory lies the definition of a structured collection of metrics and indicators, associated with the dimension of interoperability-governance, and a mechanism for gathering with regard to the latter suitable information for a number of countries from various sources. The ultimate goal is the use of this information towards the directions of raising awareness on the countries’ interoperability status, promoting best practice cases and benchmarking.

Advancing Interoperability for Agile Cross-Organisational Collaboration: A Rule-Based Approach
Abstract: The level of adoption of advanced integration technologies, by private and public organizations, in support ...more
of their electronic collaborative business transactions is still relatively low, especially among Small and Medium-sized Enterprises. Current solutions often lack a common understanding of the underlying business processes, document semantics and business rules that are imposed on them in different sectors and countries. Furthermore, software applications are not able to cope with the huge variety of differentiation in process and document semantics, stemming from the highly diverse requirements of the stakeholders. This study presents a comprehensive Model-Driven Architecture for enabling agile cross-organisational collaboration, in an international context, by integrating business and legal rules in private and collaborative processes, business documents and their resulting service orchestrations. The resulting framework, that was mostly developed and applied in the course of the EU-funded research project GENESIS, ranges from graphical process and data models and declarative rule structures to the technical specification of a hybrid software architecture for integrating rule with process and data models.

National Interoperability Frameworks: The Way Forward
Abstract: National Interoperability Frameworks (NIFs) have been established during the last years as the governmental ...more
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.

enterprises and above all decision makers are constantly trying to get the best out of the opportunities and the technologies offered, for facilitating their life and their work. One of the most active and promising domains nowadays, is eParticipation, which is actively promoted by all stakeholders, as there is a great need of reconnecting citizens with the decision makers and re-engaging them into the democratic procedures, especially as during the last years this gap is expanding, with the most convincing proof being the huge figure of voter turnout during the latest European elections. The purpose of this paper is to address these issues. Design/methodology/approach – A review of the most active and well-known eParticipation action pilot projects funded in the European Union is presented, alongside with a methodological framework that has been followed for mapping, assessing and evaluating those projects, using a beyond the state-of-the-art classification method. Findings – Conclusions of the performed work are in a position to outline the current status quo of eParticipation in Europe, highlighting lessons learned and opportunities for future activities and research. Originality/value – This paper includes valuable information towards practitioners, decision makers and administration officials, based not only on the established knowledge and on the experiences gained, but also on the identified gaps of the domain, aiming to support them in understanding the status quo of the domain and in the design process of future research roadmaps for eGovernace and policy modelling.

Implementation and Evaluation of eParticipation Systems in Western Balkan National News Agencies: The user perspective
Abstract: eParticipation is a developing field in which various implementation and evaluation methods may be used, ...more
according to each specific project’s content and context. The evaluated aspects of an eParticipation project should focus on both the technological acceptance by the users and its contribution towards participative decision making and deliberation. In this context, we present a prototype eParticipation system, as it was implemented in the National News Agencies of Albania, Fyrom and Serbia. The novelty of this electronic participation system, that allows citizens to comment and discuss the news items as they appear in the News Agencies’ web sites, inspires focusing on user reaction and investigating the suitability of the proposed eParticipation model in practice. Focusing on the user perspective, the paper presents how the Technology Acceptance Model was used to evaluate this system that spans in multiple countries, languages and cultures. The evaluation results pinpoint several technical and societal challenges that relate to the implementation of eParticipation systems in developing countries.

Achieving Interoperability through Base Registries for Governmental Services and Documents Management
Abstract: As digital infrastructures increase their presence worldwide, following the efforts of Governments to ...more
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.

Evaluation of the Impact and Adoption of E-Government Services in the Balkans
Abstract: Governments around the world are embracing the digital revolution to enhance services for their citizens....more
. However, the development of quality e-services and delivery systems that are efficient and effective is only one aspect of e-government. The essence of the latter lies as well in engaging citizenry into the use of e-government services. This chapter studies the impact and actual utilization of e-government services in certain countries of the Balkans (Bulgaria, Greece, Hungary, Romania, and Slovenia) using fuzzy numbers and statistics. Building on the elementary concept of the time that citizens/businesses spend on their transactions with public administration and taking into account the current sophistication stage of online public services, the chapter provides a framework for evaluating (a) e-government services in terms of the benefits that their use involves for citizens/businesses compared to the use of conventional ones and (b) the actual adoption (take-up) of e-government services by the aforementioned stakeholders. In this context, the scheme proposes the use of data expressed in linguistic terms with regard to the time citizens/businesses spend on transactions with public administration using either conventional or e-services, which are then converted to fuzzy numbers to be further processed so as to incorporate the uncertainty factor which is innate in the relevant estimations. The proposed framework is then applied for each one of the aforementioned countries for a basket of 20 basic public services (12 for citizens and 8 for businesses), exploiting the current sophistication stage and the actual utilization of e-government services per sophistication stage, provided by the corresponding e-government factsheets and Eurostat, the Statistical Office of the European Communities, respectively, and allowing for useful conclusions to be reached.

a decision making framework. Built around the concepts of website evaluation and e-government, the proposed framework deploys Multi-Attribute Decision Making (MADM) methods and Fuzzy Sets Theory to overcome the subjectivity and inaccuracy that characterizes the conventional models for e-government website quality assessment. The framework offers also the possibility of performing comparisons with regard to the overall quality of different implementations either at national or international level. The chapter presents a holistic and scalable approach to e-government website evaluation and it is anticipated to be of great interest to both researchers and practitioners requiring an understanding of the factors influencing the quality of e-government websites or allocating resources to the relevant implementations respectively.

Abstract: Openness, accountability, and transparency have attracted researchers’ and practitioners’ interest as ...more
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.

can improve e-participation practice. This paper describes a framework that has been developed for evaluating a number of e-participation pilots in the legislation development processes of parliaments. The framework is based on the objectives and basic characteristics of 'traditional' public participation, e-participation and the legislation development processes, as well as the existing frameworks for the evaluation of Information Systems (ISs), e-participation and traditional public participation. It includes three perspectives: process, system and outcomes evaluation; each of them is analysed into a number of evaluation criteria.

A Goal-Driven Management Approach based on Knowledge Exploitation for e-Government Projects
Abstract: The implementation of electronic Government projects in public sector organisations is a challenging ...more
task, due to technical, organisational and cultural specificities of the domain. Research shows that such IT projects have higher failure rates than similar approaches in the private sector, also indicating the lack of a method to transfer knowledge and apply best management practices in an effective way. The proposed management approach aims to recognise structure and reuse past successful attempts, in ways that support the overall viability of an e-Government project. After stating the fundamental principles of project management that apply to public sector IT projects, the authors present a conceptual model for e-Government project management, including entities such as dimensions, goals, activities, deliverables and roles that can be structured and adapted to cover all types of relevant projects in an out-of-the-box approach. This knowledge base of predefined project components can then be populated and utilised in making more informed decisions for effective project management of e-Government initiatives. This way, the proposed method supports public officials and practitioners in learning from past experience projects and in designing and running e-Government projects in a more systematic manner, thus, significantly increasing the likelihood of project success.

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 identified as the ones that were able to adapt their ...more
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.

systems. This article presents a knowledge-based methodology for constructing readiness assessment instruments for B2B integration solutions and examines its validation by conducting structural equation modeling analysis with input data from wholesale trading firms in Greece. Strong emphasis is given to the usability and appropriateness of the produced indicators and the relevant gap in literature is addressed. The B2Bi success factors that are presented and the final set of their underlying indicators can provide a starting point for conducting organizational readiness evaluations for the successful adoption of multi-enterprise integration solutions. Our methodology and findings can assist enterprises and public bodies to utilize, share, and enrich a knowledge base about B2Bi organizational readiness, throughout their evolution as part of the Knowledge Society.

Emerging Interoperability Directions in Electronic Government
Abstract: Being important at organizational, process and semantic levels, interoperability became a key characteristic ...more
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.

Abstract: Interoperability is an important characteristic of information systems, organisations, their processes and data....more
. Achieving automated collaboration of processes and systems may lead to a dramatic increase in productivity for enterprises of any size. As a result of this projected benefit, interoperability has been prescribed by numerous standardization frameworks, guidelines at enterprise level, data schemas and techniques to tackle the problem of non-communicating systems or organisations. 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. This paper goes beyond the presentation of the main milestones in this fascinating quest for collaboration between people, systems and information: it attempts to describe how this new interdisciplinary research area can transform into a vibrant scientific domain, by applying the necessary method and tools. To achieve that, the chapter presents the ingredients of this new domain, proposes its needed formal and systematic tools, explores its relation with neighbouring scientific domains and finally prescribes the next steps for achieving the thrilling goal of laying the foundations of a new science.

Towards a Scientific Approach to e-Government Research
Abstract: E-Government has an unprecedented potential to improve the responsiveness of governments to the needs ...more
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.

Application of Fuzzy Analytic Hierarchy Process to Evaluate the Quality of E-Government Web Sites
Abstract: As more and more public authorities attempt to embrace the digital revolution and place a wide range ...more
of materials on the web, from mere information to actual online services for the convenience of citizens, expectations of the service levels that sites should provide have been considerably raised, bringing up the issue of their quality evaluation. In most evaluation approaches, users are asked to provide their opinion on or weigh selected criteria through appropriate questionnaires; however their answers contain a certain level of un-determination. To this end, this paper develops an evaluation framework that overcomes this impediment by using triangular fuzzy numbers. The paper adopts Fuzzy Analytic Hierarchy Process, a fuzzy multiple attribute decision making method, to assess the quality attributes of e-government websites.

services is emerging as an important research challenge in electronic government. The eGOVSIM model that is proposed in this paper aims to provide administrations with a tool to calculate the gains from digitising and making interoperable services for citizens and businesses. The paper presents existing methods for calculating the cost of services for the administration and the service consumers, such as the Standards Cost Model (SCM) and the Activity Based Costing (ABC). Then it goes on presenting a toolset for analytical cost calculations based on the various process steps and the information needs of each governmental service. The tool supports the definition of several service provision scenarios, such as front/back office system interoperability, cross-system or cross-organisational interoperability allowing the calculation of time, effort and cost elements and relevant gains from the application of each scenario.

Abstract: As the need for interoperability infrastructures and services is more and more stressed by researchers ...more
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.

Effects of Enterprise Interoperability on Integration Efforts in Supply Chains
Abstract: Despite their business value and return on investment, multi-enterprise integration projects are unbearably ...more
costly for many companies. With a view to realizing lower integration costs and resources, enterprises are seeking partner attributes that display the ease of B2B collaboration. This paper examines the relationship of B2B interoperability to integration effort. It breaks down enterprise interoperability into five layers (network, data, process, application, business) and investigates the particularity and effect of each. The research model is validated by a field study using data from 239 firms. Interoperability at the business, process, and data levels is found to be significantly but negatively associated with integration efforts. Interoperability at the application level showed little relation to integration efforts, and interoperability at the network level had a nonsignificant positive relationship with integration efforts. The research model and findings are a starting point for assessing interoperability with a potential partner at each layer and for estimating the involved integration effort, with a view to aiding e-partnership decisions and B2B integration management.

and upcoming research fields; providing governmental services to citizens with the use of modern technologies and achieving interoperability which will result in the seamless cooperation of existing heterogeneous systems. The final outcome of such attempts should be fully functional and expandable information systems undertaking the task of offering governmental services to the wider public. Those systems should be user-friendly to both the end users (the citizens and the business) and public servants and should be regarded as virtual holistic systems, where ‘black boxes’ take care of the whole process of implementation and the interconnection with various existing systems being used by public administrations. This paper, presents a complete methodological approach for deploying and operating such systems, as piloted in two Greek municipalities with over 50,000 citizens and 3,000 businesses in each.

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 issues still remain unsolved. As various initiatives ...more
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.

Knowledge Management in SMEs: A Research Agenda
Abstract: KM is an emerging area, which has gained interest by both enterprises and academics. The effective implementation ...more
of a KM strategy is considered as a 'must' and as a precondition of success for contemporary enterprises, as they enter the era of knowledge economy. Big enterprises seem to have fully realised the importance of KM for their operation and the advantages that can offer and in this way, the majority of proposed methodologies, systems and tools (from the part of the research community) is addressed/concerned with big enterprises. This is not the case however for SMEs, the majority of which seem to consider KM as a non-affordable luxury and consequently, the research regarding KM and SMEs has been slow in formulating respective frameworks, methodologies and tools and there are still many pending issues that have to be addressed. However, KM has a lot to offer to SMEs. In this way, this paper attempts to propose a research agenda for the relation of KM and SMEs. The discussion presented in this paper should be of value to researchers and practitioners.

Promoting Electronic Participation Systems in the Balkans: The case of National Press Agencies
Abstract: While eParticipation systems are being deployed in many European member states, their operation in converging ...more
regions is still a problem. Socio-economic conditions, familiarisation with new democratic processes and low penetration of information technology still pose barriers for these eParticipation applications and their successful deployment calls for joint participation and cooperation of citizens and organisational bodies in order to form a unified framework consisting of guidelines and common codes of ethics. This paper presents a case study of the establishment of an eParticipation platform based on the cooperation of national news agencies in the converging regions of the Balkans.

and systems is emerging as an important research challenge in interoperability for governments and administrations. The Government Interoperability Maturity Matrix (GIMM) that is proposed in this paper aims to provide administrations with a simple, self-evaluation method that can be used to assess the current status of the administrations concerning eGovernment interoperability and the steps that need to be taken to improve their positioning in respect to system implementation and services provision to citizens and businesses. The paper expands the three types of interoperability considered in the European Interoperability Framework (EIF) identifying several Interoperability Attributes that need to be taken into consideration in order to evaluate each organisation positioning in eGovernment interoperability and presents the rational of the Methodology that has been formulated and introduced. Within this modeling context, levels of existing interoperability status of organisations are clearly defined, while certain practices or directions lead to interoperability state changes within the maturity matrix.

Electronic Criminal Record in Greece: Project Management Approach and Lessons Learned in Public Administration
Abstract: The implementation of eGovernment is a burgeoning phenomenon across the globe. However, a review of the ...more
IS literature reveals the inability of public administration organizations to complete information technology projects successfully. Unless governments learn to manage the government transformation projects, these e-dreams will turn into global nightmares. The shortage of studies on eGovernment implementation presents a knowledge gap that needs to be plugged. This paper describes and analyzes the computerization of the existing paper-based criminal record system in a public organization in Greece. Our intent is to present anapplication of a goal driven project management methodology named eGTPM in order to use it as a methodological reference when navigating in the open sea of information technology project implementations in the area of public administration. The successful implementation of the specific project indicates that the application of eGTPM approach could provide a solution to achieve government transformation objectives more effectively and efficiently.

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 enable private and public organizations to seamlessly ...more
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).

Special Issue: Interoperability Approaches for Enterprises and Administrations Worldwide
Abstract: During the last few years, research and practice worldwide have shown that enhancing interoperability ...more
among organizations, systems or software applications is a multi-disciplinary issue of critical importance, touching upon processes, data and technical standardization. Fortunately, researchers and practitioners have started to realize the impact of interoperability in achieving true one-stop service provision for citizens and businesses, in fostering collaboration between enterprises or in minimizing the needed investment for maintaining complex systems. Current research results show that there exist common practices to be shared among public sector organisations and private sector enterprises, in attempts related with aligning organisation and processes, tackling semantic and technical shortcomings, building relevant architectures and finally achieving the legal interconnection and co-operation of systems. The identification of such common areas between eBusiness and eGovernment can then lead to a joint exploration, enhance reuse of the real paradigms and real exploitation of results by enterprises and administrations. Also future interoperability research directions, as emerging from relevant strategies and research roadmaps of important stakeholders, and also from relevant research workshops, are outlined. Furthermore, it is argued that interoperability research should be extended towards "knowledge interoperability" as well, and deal with the development of methods and architectures enabling the exchange of knowledge among co-operating organizations.

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 a holistic approach in electronic transactions, ...more
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.

Realising the Perspective Inter-Domain Interoperability: The Practical Power of Hybrid Architectural Approaches in Integrating Processes, Data and Services Between Businesses and Administrations
Abstract: Escalating economic and societal demands of today, along with the continuous advancements in ICT, push ...more
enterprises and administrations to move towards networked paradigms and leverage electronic transactions in their everyday practices. Although technical solutions providing the necessary interoperability means to enable such practices have been rigorously provided during the last years, their adoption and application by the foregoing stakeholders still remains limited. Several qualities of the existing solutions in technical and business level concerning the way the manage workflows, data mappings, business and legal rules along with the use of proprietary technologies and their inability to be readily set up and deployed, act as the main inhibitors for any potential users. The present work discusses the characteristics of the predominant centralized and decentralized architectural patterns for eTransactions, identifies the weak points of every case and proposes a hybrid architectural approach that brings together the "best of breed" of both paradigms. Additionally, specific insights, methodologies and underlying technologies are proposed with an objective to support the effective implementation of the proposed architecture and its basic components.

Designing Generic Municipal Services Process Models towards eGovernment Interoperability Infrastructures
Abstract: Public Administration desks are in any country the most active point of transactions between the state ...more
governments and the citizens. This fact emphasises the importance of services offered by Public Administrations and in the modern technological era, it is essential for Information Technology to provide solutions for transforming these traditionally offered services into electronic transactions that could be initiated over the Internet, aiming at the facilitation of the citizen's life, who is the eventual "client" of any government.. Although public administrations have strived over the last few years to meet this goal, their individual attempts resulted in isolated, ad-hoc systems, offering a small piece of the whole service bouquet. As the connectivity generated by the Internet is opening new opportunities in service delivery, public administrations are seeking ways to deliver integrated value-adding services though an Interoperable environment. The goal of a systematic service composition, which will guarantee eGovernment Interoperability, can be accomplished with an effective method of modeling the public services, in order to expose their interfaces and their actual workflow. Applying this method in Greek Municipalities by respecting the context of the emerging Greek eGovernment Interoperability Services Framework, various services have been analyzed, leading to corresponding generic process patterns.

adapt, collaborate and interoperate with each other. However, the diversity in the way they organize their knowledge through ontologies, brings about the crucial need for establishing semantic interoperability between all communicating parties. One approach to solve this problem is the use of MENTOR, a particular methodology based on the development of a common, top-level “reference ontology” that serves as an intermediary in the communications between the various enterprises, harmonizing not semantically coincident ontologies that represent the same segment of reality. This methodology allows the enterprises to keep their own ontologies and semantics unchanged internally, enhancing thus semantic interoperability between them with low intra-enterprises changes, cost and effort. This paper proposes the integration of MENTOR methodology within an Interoperability Service Utility (ISU), i.e. an intelligent system that serves as a utility software component to promote interoperability among communicating enterprises. The present work describes design and implementation specifications of such an infrastructure and explains how MENTOR methodology will enable the proposed ISU to seamlessly provide the necessary set of e-services that will deliver and sustain interoperability across its enterprise users.
