Recent years have seen an increasing social, political and economic emphasis on the use of e-Learning methodologies that hold out the promise of wider access, higher quality and lower costs. There are now a plethora of proprietary platforms - some commercial and closed, some homegrown and open - shoe only common feature is their incompatibility with each other. Recently, the notion of a portal has gained credence as a guiding technical principle that can be used to integrate diverse information services and provide an organisational focus. Portals promise a common environment and single access point for everyone from anonymous web site visitors to indentured users of e- Learning resources. In 1999 the UK JISC Committee on Integrated Learning Environments (JCIEL) was formed in recognition of the need for understanding integration issues. INSIDE [1], an Institutionally Secure Integrated Data Environment, was one of several projects sponsored by the JCIEL programme. It proposed the creation of a user-centric portal that provided managed learning functionality for academic staff and their students. The result, which is described in this paper, is MMS, a module management system.
