You keep writing that uPortal is a framework. Isn't that just an empty yuppie marketing word?

No. I'm using the word 'framework' in its widely-accepted, Software Engineering sense (Wirfs-Brock1991). A framework is a reusable design, expressed as a set of classes, that can serve as a solution to a family of related problems and support reuse at a larger granularity than classes. A mature framework allows components to be reusedas "black boxes", that is, a programmer can incorporate them into a system under construction without knowing their implementations (Johnson1998). Most frameworks in widespread use today are for constructing graphical user interfaces (GUIs) for traditional desktop applications. uPortal is different in that it's a framework for developing a web portal and developing content for display within that portal, but the underlying principal of both kinds of frameworks is the same: the framework provides programmers with an infrastructure that supports a coherent architectural model, allowing developers to concentrate on applying their expertise to the problem domain. In the case of uPortal, the framework takes care of the common functionality that every portal needs, so that you can implement the parts that are important and specific to your campus.
