THE FRAMEWORK What Is ODP About? The ODP reference model Viewpoints Fundamental concepts Useful building blocks Service orientation Human computer interaction The right tools for the job THE VIEWPOINTS Enterprise Viewpoint Designing with communities Identifying roles Organizational structure Roles and role filling More than one community Community behavior Accountability and related concepts Quality of service and other constraints Identifying the system's user interfaces Writing enterprise specifications Information Viewpoint The primacy of information The elements of the information language Writing information specifications Structure of the information specification Relationship with other viewpoints Computational Viewpoint Designing with computational objects Computational objects Bindings Interaction between computational objects Environmental contracts and transparencies Writing computational specifications Relationship with other viewpoints Engineering Viewpoint What is the engineering viewpoint for? Objects and distribution Node architecture Channel architecture Common functions and processes Writing engineering viewpoint specifications Incorporating current technologies Relationship with other viewpoints Technology Viewpoint Linking to the real world The elements of the technology language Relationship with other viewpoints Correspondences--Joining It All Up The need for correspondences Different kinds of correspondence Correspondences required by the ODP architecture Anatomy of a correspondence specification Taking a formal view Examples of correspondences Tool support for specifying correspondences USING ODP Conformance--Does It Do the Right Thing?

About the Author

Peter F. Linington is Emeritus Professor of Computer Communication at the University of Kent. He has been involved in the standardization of the ODP Reference Model and its various supporting standards since the activity started. He has also co-chaired WODPEC, the main workshop in this area, since its inception. Zoran Milosevic is a principal of Deontik Pty Ltd., a consulting and software company specializing in business processes, business policies, complex event processing, and enterprise architectures. He was the founder of IEEE's EDOC conference and was involved in the standardization of the ODP Enterprise Language. Akira Tanaka is a founder of view5 LLC, a consulting company that applies viewpoints and model-based approaches to software development. He has been involved in RM-ODP standardization from its early days. Antonio Vallecillo is a Professor of Languages and Information Systems at the University of Malaga. His research interests include open distributed processing, model-based engineering, componentware, and software quality. He was co-editor of ITU-T Rec. X.906 | ISO/IEC 19793 (UML4ODP) and the revised versions of RM-ODP Parts 2 and 3 (ITU-T X.902-X.903 | ISO/IEC 10746-2/3).
