The University of Delaware has a powerful legacy SIS system. The University plans to replace this system in 2004-05. In the meantime, we have populated WebCT rosters using custom written scripts and batch jobs. This paper describes how these scripts have evolved into an administrative web application, which integrates information from a variety of existing campus systems to help automate the administration of WebCT. It also discusses future directions and lessons learned.
