Uwe M. Borghoff - Böcker

Key to our culture is that we can disseminate information, and then maintain and access it over time. While we are rapidly advancing from vulnerable physical solutions to superior, digital media, preserving and using data over the long term involves complicated research challenges and organization efforts.Uwe Borghoff and his coauthors address the problem of storing, reading, and using digital data for periods longer than 50 years. They briefly describe several markup and document description languages like TIFF, PDF, HTML, and XML, explain the most important techniques such as migration and emulation, and present the OAIS (Open Archival Information System) Reference Model. To complement this background information on the technology issues the authors present the most relevant international preservation projects, such as the Dublin Core Metadata Initiative, and experiences from sample projects run by the Cornell University Library and the National Library of the Netherlands. A rated survey list of available systems and tools completes the book.With this broad overview, the authors address librarians who preserve our digital heritage, computer scientists who develop technologies that access data, and information managers engaged with the social and methodological requirements of long-term information access.

A comprehensive survey of distributed file and operating systems presently in existence or of historical interest. It covers the major design issues of distributed systems and allows the reader to understand and compare the different approaches taken. The survey is organized as an encyclopaedia, and each system is independently described. The descriptions of the systems accord with a catalogue of criteria covering the major design issues, such as transparency levels, heterogeneity, security, and availability. Also included in the volume are a list of contact addresses and more than 600 references to the literature.

The value of an organization is given not just by its tangible assets but also by the knowledge embodied in its employees and in its internal and external structures. While explicit knowledge can be shared as information and is easy to handle, this tacit knowledge has been neglected by effectiveness-oriented management techniques but is crucial for both the operational efficiency and the core competencies of an organization. This book provides a survey of the use of information technology for knowledge management, and its chapters present specific research on how technologies such as computer-supported cooperative work (CSCW), workflow, and groupware can support the creation and sharing of knowledge in organizations.

The terms groupware and CSCW (computer-supported cooperative work) have received significant attention in computer science and related disciplines for quite some time now. This book is a revised and extended version of the 2nd edition of the German textbook "Rechnergestützte Gruppenarbeit: Eine Einführung in verteilte Anwendungen". It has two main objectives: first, to outline the meaning of both terms, and second, to point out both the numer­ ous opportunities for users of groupware and the risks of applying such sys­ tems. The book intends to introduce an area of distributed systems, namely the computer support of individuals trying to solve a common problem in cooperation with each other but not necessarily having identical work pi aces or working times. Computer-supported cooperative work is an interdisciplinary application domain. It can be viewed as a synergism between the areas of distributed sys­ tems and (multimedia-) communication on the one hand and between those of information science and socio-organizational theory on the other hand. Thus, the book is meant to help students of aH these disciplines, as weH as users and developers of systems which have communication and cooperation within groups as top priorities.
