This workshop reader, in a way, presents the width of the ongoing research activities in object-orientation. However, we feel one can classify these activities into three cate- ries: . Domain-speci?c: Several activities focus on a single application, e.g. telec- munication, or computer-science, e.g. real-time and mobility, domain. Research tries to address the domain-speci?c problems of object-oriented technology. . Design issues: Object-oriented design has been an issue for at least a decade, but one can identify an increasing focus on formal approaches and on the evo- tion and re-engineering of existing object-oriented software. . Beyond object-orientation: The object-oriented paradigm will, at some point, be replaced by a subsequent paradigm and several research efforts investigate alternative or extended approaches. Examples are extended language expr- siveness for, e.g. design patterns and frameworks, component-oriented p- gramming and aspect-oriented programming. 2 Contents The remainder of this book is a selection and re-iteration of the contributions to 12 workshops (of a total of 15) held during the ECOOP'97 conference. The workshops generally relate to one of the above categories.
