Abstract
A crucial aspect of the architecture of a software system is its
decomposition into components and the specification of component
interactions. In this report we use a variant of extended event traces
as a graphical technique for the description of such component
interactions. It allows us to define interaction patterns that occur
frequently within an architecture, in the form of diagrams. The diagrams
may be instantiated in various contexts, thus allowing reuse of
interaction patterns. Our notation contains operators yielding not only
exemplary but complete behavior specifications. Extended event traces
have a clear semantics that is based on sets of traces. We present
several application examples that demonstrate the practical use of our
notation
