  The Hellenic Open University has embarked on a large-scale effort to enhance
its textbook-based material with content that demonstrably supports the basic
tenets of distance learning. The challenge is to set up a framework that allows
for the production-level creation, distribution and consumption of content, and
at the same time, evaluate the effort in terms of technological, educational
and organizational knowledge gained. This paper presents a model of the
educational process that is used as a development backbone and argues about its
conceptual and technical practicality at large.
