Abstract: This is the so-called Progress Report which is handed in as partial fulfilment of the requirements for the Ph.D. degree. This report serves two purposes: a description of the research I have been doing so far as part of my Ph.D. program, as well as a description of my plans for future research. I have worked with patterns from several perspectives, but always with the aim of exploiting their usefulness as much as possible. My work with patterns has followed three lines; preserving the benefits of design patterns, solving the trace problem by saving the core of patterns in a library, and introducing the concept of patterns to a Danish audience by giving the use perspective on patterns. Finally, my plans for future research are described.
