Semantic Web services promise to automate tasks such as discovery, mediation, selection, composition, and invocation of services, enabling fully flexible automated e-business. Their usage, however, still requires a significant amount of human intervention due to the lack of support for a machine-processable description. In this book, Jos de Bruijn and his coauthors lay the foundations for understanding the requirements that shape the description of the various aspects related to Semantic Web services, such as the static background knowledge in the form of ontologies, the functional description of the service, and the behavioral description of the service. They introduce the Web Service Modeling Language (WSML), which provides means for describing the functionality and behavior of Web services, as well as the underlying business knowledge, in the form of ontologies, with a conceptual grounding in the Web Service Modeling Ontology. Academic and industrial researchers as well as professionals will find a comprehensive overview of the concepts and challenges in the area of Semantic Web services, the Web Services Modeling Language and its relation to the Web Services Modeling Ontology, and an in-depth treatment of both enabling technologies and theoretical foundations.

According to the W3C Semantic Web Activity [1]: The Semantic Web provides a common framework that allows data to be shared and reused across appli- tion, enterprise, and community boundaries. This statement clearly explains that the Semantic Web is about data sharing. Currently, the Web uses hyperlinks to connect Web pages. The Semantic Web goes beyond that and focuses on data and envisions the creation of the web of data. On the Semantic Web, anyone can say anything about any resource on the Web. This is fully based on the concept of semantic - notations, where each resource on the Web can have an assigned meaning. This is done through the use of ontologies as a formal and explicit representation of domain concepts and their relationships [2]. Ontologies are formally based on description logics. This enables agents and applications to reason over the data when searching the Web, which has not previously been possible. Web 2. 0 has gradually evolved from letting the Web users play a more active role. Unlike the initial version of the Web, where the users mainly "consumed" content, users are now offered easy-to-use services for content production and publication. Mashups, blogs, wikis, feeds, interface remixes, and social networking/tagging s- tems are examples of these well-known services. The success and wide adoption of Web 2. 0 was in its reliance on social interactions as an inevitable characteristic of the use and life of the Web. In particular, Web 2.

Hypermedia & the Web An Engineering Approach David Lowe, University of Technology, Sydney, Australia Wendy Hall, University of Southampton, UK The rich online world offered through the Web is marred by the chaos which underlies it. At the very early stages of understanding how to harness the power of this new medium, electronic document creators, managers and researchers often spend time on technology innovations at the expense of adopting the sound engineering principles which have paid such dividends in the software industry. Hypermedio & the Web approaches interactive information (concentrating on hypertext documents) as a structure requiring management, quantification and documentation. From analysing the purpose for which a website, CD-ROM or online archive is created, assessing the characteristics and resources needed for the process of building each one, to the assessment of the end product itself, this book attempts to carve out features that are essential to the successful structuring of information in an electronic environment. This is an ambitious book charting an emerging discipline. It is an essential tool to help developers and educators shape and maintain useful and relevant electronic information. 'Hypermedia Engineering hasn't produced many tangible benefits in real-life situations, because very few people practise it. That's why the book is needed.' David Barron, Southampton University 'This book is interesting and excellently fulfills a current need [by] providing an exhaustive and up-to-date vision of the hypermedia field.' Fabio Vitali, University of Bologna 'The strength of this book is its breadth - it covers many of the issues in hypermedia with examples from thetechnical to the managerial. Students could use these as starting points when designing or evaluating hypermedia systems.' David Sharp, Imperial College of Science and Technology 'Information systems developers and managers should find this a helpful guide for developing hypermedia applications.'

Durch die Weiterentwicklung der kommunikationstechnischen Infrastruktur ergeben sich neue Freiraume bei der Distribuierung von Informations- und Kommunikationssystemen (IKS). Das Buch stellt ein computergestutztes Entscheidungsmodell zur Bestimmung des optimalen Distribuierungsgrades von IKS vor und dokumentiert die Entwicklung eines Prototyps. Die Diskussion der Rahmenbedingungen baut auf einem kybernetischen Unternehmensmodell auf, das es ermoeglicht, die Lebensfahigkeit eines Systems in seiner Umwelt zu untersuchen. Die geforderte Eigenschaft der Rekursivitat des Modells fuhrt zu dem Schluss, dass auch das IKS in einem Unternehmen hinsichtlich seiner Lebensfahigkeit beschrieben werden kann. In der Folge wird die Organisation unter einem strukturellen Aspekt untersucht. Dabei wird die Dimension der Distribuierung und das Distribuierungskontinuum beschrieben. Der Prozess der strategischen Unternehmensplanung, die Ableitung von Informatikprojekten (Projektportfolio) und Informatikzielen und die darin begrundeten Einflusse auf eine Distribuierungsentscheidung bilden den Gegenstand weiterer Untersuchungen. Als dritte Rahmenbedingung wird dann die Bedeutung der Entwicklung von Normen und Standards diskutiert. Dabei steht weniger der technische Aspekt im Vordergrund. Vielmehr werden die Anforderungen untersucht, denen ein IKS genugen muss, wenn der Distributionsgrad nicht von den technischen Moeglichkeiten sondern von anderen Faktoren bestimmt wird. Der zweite Teil der Arbeit beinhaltet eine Beschreibung der logischen Struktur des Prototyps, der Entwicklungsumgebung, der zugrundeliegenden Datenstruktur und der Benutzerschnittstelle anhand einer Beispiel-Konsultation.

In a world that is awash in ubiquitous technology, even the least tech-savvy know that we must take care how that technology affects individuals and society. That governments and organizations around the world now focus on these issues, that universities and research institutes in many different languages dedicate significant resources to study the issues, and that international professional organizations have adopted standards and directed resources toward ethical issues in technology is in no small part the result of the work of Simon Rogerson. - Chuck Huff, Professor of Social Psychology at Saint Olaf College, Northfield, Minnesota In 1995, Apple launched its first WWW server, Quick Time On-line. It was the year Microsoft released Internet Explorer and sold 7 million copies of Windows 95 in just 2 months. In March 1995, the author Simon Rogerson opened the first ETHICOMP conference with these words: We live in a turbulent society where there is social, political, economic and technological turbulence ... it is causing a vast amount of restructuring within all these organisations which impacts on individuals, which impacts on the way departments are set up, organisational hierarchies, job content, span of control, social interaction and so on and so forth. ... Information is very much the fuel of modern technological change. Almost anything now can be represented by the technology and transported to somewhere else. It's a situation where the more information a computer can process, the more of the world it can actually turn into information. That may well be very exciting, but it is also very concerning. That could be describing today. More than 25 years later, these issues are still at the forefront of how ethical digital technology can be developed and utilised. This book is an anthology of the author's work over the past 25 years of pioneering research in digital ethics. It is structured into five themes: Journey, Process, Product, Future and Education. Each theme commences with an introductory explanation of the papers, their relevance and their interrelationship. The anthology finishes with a concluding chapter which summarises the key messages and suggests what might happen in the future. Included in this chapter are insights from some younger leading academics who are part of the community charged with ensuring that ethical digital technology is realised.

First Practical Guide to Integrating Risk Management, Business Continuity Management and Corporate Governance From Two World-Renowned BCM Pioneers Who Have Served on the British Standards Institution (BSI) Team Creating a British and International Standard for Risk Management. The U.S. Department of Homeland Security (DHS) is currently developing disaster preparedness standards for businesses. DHS is incorporating language from the British Standards Institution (BSI) because it "provides a management systems approach to business continuity and integrates risk management disciplines and processes." The two authors of this now classic text in the field have been directly involved in developing those BSI standards. Here they bring you a distillation of their worldwide experience in pioneering the integration of the disciplines of risk management and business continuity. This practical guide is endorsed by: * * * The Business Continuity Institute * * * The Institute for Risk Management * * * Disaster Recovery Institute International It includes numerous helpful features: * * * Chapter objectives, summaries and bibliographies; charts, sample forms, checklists throughout * * * Plentiful case studies, in boxed text, drawn from enterprises around the globe, including the UK, US, Europe, Australia, Asia, etc. * * * Boxed inserts summarizing key concepts * * * Glossy of 150 risk management and business continuity terms * * * Timely topics, including stakeholder management, supplier management, outsourcing, the people factor, technology recovery, and communication, both internally and externally. * * * Wide range of challenges, including supply chain disruptions, media and brand attack, product contamination and product recall, bomb threats, chemical and biological threats, etc. * * * Instructions for designing/executing team exercises with role playing to rehearse scenarios * * * Guidance on how to develop a business continuity plan, including a Business Impact Analysis * * * Ideal for senior undergraduate, MBA, certificate, corporate training programs; in use at 50+ campuses worldwide * * * Instructor Materials on CD, including PowerPoint slides and syllabus for 12-week course with lecture outlines/notes, quizzes, reading assignments, discussion topics, projects * * * Authors with extensive international experience in all aspects of risk management and business continuity, having worked with organizations in a combined total of 50 countries The authors' message is that risk management has become a strategic tool in managing all risk across an organization, and that BCM forms one more important tool in a much wider and coordinated risk management program. They are now complementary disciplines that must be understood and supported by your organization as a whole, including CEO's, directors, non- executive directors, risk managers, continuity managers, internal and external auditors, investment managers, compliance managers, finance directors, human resource managers, project managers, regulators, corporate trainers and other stakeholders. After discussing the relationship between risk management and BCM, the authors take the reader through the business continuity management cycle: how to understand the organization and its culture; continuity strategies; how to develop and implement a business continuity response, including developing a Business Impact Analysis; building and embedding a business continuity culture; testing/exercising a plan, along with benchmarking, maintenance and audit. "This book is a must read for those senior managers, risk managers and continuity managers who have the vision to see both the new opportunities and the new responsibilities of business continuity management." - George J. Mitchell, Chairman, DLA Piper Rudnick Gray Cary; Former Senate Majority Leader and U.S. Senator for Maine.

This book is a guide to implementation of World-Class Business Continuity Management within an enterprise. It may be used as a step-by-step guide by those new to Business Continuity Management or dipped into by the more seasoned professional for ideas and updates on specific topics. There is no absolute "right way" to perform business continuity management - although there are plenty of wrong ways. Business Continuity is not rocket science: it is applied common sense. Yes, experience helps, but it is no mystic art. This book makes the processes transparent and provide the reader with everything necessary to do the job. Many examples are provided throughout this guide: these all have their roots in real cases and real organizations, and come heavily laden with pragmatism. Over fifteen years of business continuity experience in environments large and small, public and private, has gone into developing the methods described. Your own "right way" for business continuity management means picking, matching and tailoring from the cases and examples provided and combining these with existing best practice within your organization. EXCERPT FROM THE PREFACE Melvyn Musson, FBCI, CBCP, CISSP I was very pleased to be asked to write a preface to this much-needed book. There are many books that have been written covering various aspects of hazard control, emergency response, disaster recovery and business continuity, but not one that pulls all areas together under the auspices of the individual sections of the BCI and DRII Professional Practices. Why my interest? To quote from a letter I wrote to the National Fire Protection Association (NFPA) in 1991 when they were considering the establishment of a Technical Committee to develop a Standard on Disaster Management: "Disaster Management, or Business Continuation Planning as we prefer to call it, is a natural progression from Hazard/Loss Control through Emergency Response to the recovery process. "The best hazard/loss control programs cannot prevent emergency or catastrophic situations occurring. The emergency response procedures that most companies have developed or which may be required by law, deal with such aspects as initial fire fighting, evacuation, life safety, etc. - what one might term the stabilization of the situation. They cover the first hours of the emergency. They do not deal with the long-term recovery, which could take several months. "Disaster Management, or some other similarly named program, is needed to enable the company to institute procedures to return to normal operations as soon as possible. That standard is now available as NFPA 1600: Standard on Disaster/Emergency Management and Business Continuity Programs. Within that standard are details of the BCI/DRII Professional Practices, albeit as part of the various sections of the standard and not as an individual, specific section. In addition to NFPA 1600, other standards and guides such as BS7779 in Great Britain and the recent Australian Risk Management Standard are incorporating the Professional Practices either by specific reference or wording relating to the practices. The advent of the Turnbull Report introduces a new consideration and need, which the Professional Practices can support. This makes it all the more important to have a reference material that can clearly detail what should be considered in each of the ten subject areas, together with appropriate examples and details of not only the benefits but also the problems that can be expected with each of those subject areas. Andrew Hiles has been able to do so in the development of this book. In addition, since Andrew intends to issue periodic updates, this book becomes a living document, which will address both changes in the Professional Practices and developments within the industry.
