This volume, the 8th in the Transactions on Aspect-Oriented Software
Development series, contains two regular submissions and a special
section, consisting of five papers, on the industrial applications of
aspect technology. The regular papers describe a framework for
constructing aspect weavers, and patterns for reusable aspects. The
special section begins with an invited contribution on how AspectJ is
making its way from an exciting new hype topic to a valuable technology
in enterprise computing. The remaining four papers each cover different
industrial applications of aspect technology, which include a
telecommunication platform, a framework for embedding user assistance in
independently developed applications, a platform for digital publishing,
and a framework for program code analysis and manipulation.
