In this paper, we describe how ORM is extended, and combined with Concurrent Task Trees (CTT) to model the content as well as the functionality of a web system in the web design method WSDM. As WSDM uses an audience driven design approach, the use of ORM is somewhat different from its use for data modeling in the context of databases. We discuss the differences. We also discuss the benefits of using ORM for our purpose, modeling web systems using an audience driven approach.
