This book constitutes the refereed proceedings of the Second International Conference on Meta-Level Architectures and Reflection, Reflection'99, held in St. Malo, France in July 1999. The 13 revised full papers presented were carefully selected from 44 submissions. Also included are six short papers and the abstracts of three invited talks. The papers are organized in sections on programming languages, meta object protocols, middleware/multi-media, work in progress, applications, and meta-programming. The volume covers all current issues arising in the design and analysis of reflective systems and demontrates their practical applications.

This book constitutes the refereed proceedings of the 10th European Conference on Object-Oriented Programming, ECOOP '96, held in Linz, Austria, in July 1996.
The 21 full papers included in revised version were selected from a total of 173 submissions, based on technical quality and originality criteria. The papers reflect the most advanced issues in the field of object-oriented programming and cover a wide range of current topics, including applications, programming languages, implementation, specification, distribution, databases, and design.

In October 1983 an informal meeting was organized in Le Cap d'Agde with the help of the BIGRE bulletin. Sixty people turned out to hear more than ten presentations on object-oriented programming. More important was their unanimous demand for other, more structured encounters. So, about one year later, the Object group was created by AFCET. A second workshop was organized in Brest, and again one year later in Paris, each time showing increased attendance and interest. The success of these meetings and the fact that similar activities were taking place in other European countries, especially Great Britain and Germany, led to the idea of an annual European Conference, providing a forum for theorists and practitioners interested in the object-oriented programming paradigm. It is impossible to acknowledge here all the people and organizations that welcomed with great enthusiasm the birth of the ECOOP conference and contributed to its organization. More than a hundred submissions were received and the program committee had the unpleasant task of turning down many valuable contributions. We hope, however, that the selection of papers for ECOOP'87 emphasizes the fundamental issues and problems of object-oriented programming and will point toward interesting future research directions.
