Several reengineering environments have been created to provide for a unified infrastructure in which various approaches can be employed together. While the collaboration between tools is very strong within such environments, currently the inter-environmental collaboration is very weak and happens mainly at the level of data-files exchange. Consequently, the different groups of researchers are only collaborating shallowly via data, rather than at the level of analysis. In this demo, we present NOREX, a distributed reengineering environment that allows different groups of researchers to transparently use and combine existing techniques, and share their own, transcending any parochial barriers (e.g., implementation language or environment).
