Object-oriented metalevel architectures, metaobjects, and reflection are becoming more and more important in computer science. This applies to traditional fields such as artificial intelligence and object-oriented programming languages as well as to parallel processing and operating systems. Advances in Object-Oriented Metalevel Architectures and Reflection presents the research currently receiving a great deal of attention in the field. The book is structured as follows: an introductory chapter lays the necessary foundation for the reader new to the field. The next five parts discuss the following subjects: operating systems, artificial intelligence, languages, concurrent objects, and application support. Each part itself contains a brief introduction that presents the basics for understanding the particular area.
