....class precedence list computation in case of multiple inheritance, method lookup) Currently, many non language applications follow the Meta Object Protocol approach. For instance, Silica, a customizable open ended window manager [8] Muse operating system [10] and a CSCW toolkit project [11]. They all emphasize flexibility and openness provided by the Meta Object Protocol approach. Static and dynamic flexibility of process centered environments have been extensively discussed, mainly through process model evolution [12] Evolution of enactment mechanisms has received less interest. ....

Another important aspect that must be considered is integrity specification and enforcement at the level of individually evolving classes and at the level of the global network of classes. A second decision in CPCE is that integrity properties shall not be encoded into the meta process, because ....

....of itself. In order to support tailorability, this selfrepresentation needs to be manipulatable and causally connected to the represented aspects, i.e. if the representation changes, the application changes as well. In this sense the application is a reflective computational system (see [11] [3] points out the relevance of reflective architectures for the design of tailorable CSCWapplications. 5. State of the art and research questions In the following we want to describe design issues and options for tailorability on the three levels of component architectures, taking into account ....

....might provide generic support for a wide range of groupware. This research has followed two threads which may be characterised as extending either current language models or current operating system support with functionality tailored to the needs of groupware applications. For example, Dourish [Dourish, 1994] has explored the applicability of reflection in toolkit design. His approach simplifies the construction of specific classes of groupware supported by his toolkits. He reports that adding reflection to the programming language via a reflective toolkit facilitates the building of groupware ....
