De-fragmenting Knowledge: Using Metadata for Interconnecting Courses

M. Ronchetti, A. Giuliani, and P. Saini (Italy)


Metadata, Knowledge Management


E-learning systems are often based on the notion of "course": an interconnected set of resources aiming at presenting material related to a particular topic. Course authors do provide external links to related material. Such external links are however "frozen" at the time of publication of the course. Metadata are useful for classifying and finding e-learning artifacts. In many cases, metadata are used by Learning Management Systems to import, export, sequence and present learning objects. The use of metadata by humans is in general limited to a search functionality, e.g. by authors who search for material that can be reused. We argue that metadata can be used to enrich the interconnection among courses, and to present to the student a richer variety of interconnected resources. We implemented a system that presents an instance of this idea.
