The idea of legacy systems which conserve some valuable parts of an outdated software system is applied to conserving the Knowledge Base (KB) engineered into an existing Knowledge-Based System (KIM) on
corrosion. Preliminary work is reported on incorporating this KB into a framework which combines hypermedia and KBS technologies. The user interface to this new framework is similar to browsing on the World Wide Web. As well as browsing, the framework allows users to interrogate the corrosion KB, either to obtain advice or to generate computed links to other parts of the hypermedia. It also allows new documents, such as case studies, to be linked into the hypermedia semi-automatically. This paper outlines the main features of the end-product, some of the design details and the current progress.
