The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries. It is a collaborative effort led by W3C with participation from a large number of researchers and industrial partners. It is based on the Resource Description Framework (RDF), which integrates a variety of applications using XML for syntax and URIs for naming.

"The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation." -- Tim Berners-Lee, James Hendler, Ora Lassila, The Semantic Web, Scientific American, May 2001

Knowledge Manifolds

Traditional educational architectures are teacher-centric and founded in curricular-based knowledge pushing.  The Knowledge Management Research group at CID  is developing a learner-centric educational architecture called a knowledge manifold, which supports knowledge-pulling based on interest.
