Cooperative computing is an important computing paradigm to enable different parties to work together towards a pre-defined non-trivial goal. It encompasses important technological areas like computer supported cooperative work, workflow, computer assisted design and concurrent programming. As technologies continue to advance and evolve, there is an increasing need to research and develop new classes of middlewares and applications to leverage on the combined benefits of Internet and web to provide users and programmers with highly interactive and robust cooperative computing environment. This book is a compilation of the papers that were presented at the International Workshop on Cooperative Internet Computing (CIC2002). The contributed papers address a broad spectrum on cooperative internet computing, ranging from the more fundamental modeling and specification issues of cooperative systems, to the more application-oriented issues on the popular XML-related system design and implementation. To help structure the book, we have organized these papers into four broad areas of interests: + Distributed Objects and Videos, + Web and E-commerce, + XML and Query Processing, + Modeling and Specification. Cooperative Internet Computing is designed to meet the needs of a professional audience composed of researchers and practitioners in industry. This book is also suitable as a reference text for graduate level students in Computer Science.
