This presentation was part of the SemHE workshop at ECTEL09. It told the story about how we have built Talis Aspire to be a native linked data application and how we are to use that as the basis for learning resource recommendation. The presentation goes on to warn the audience of four major areas they should think about when building applications on linked data - sustainability, provenance, licensing and reliability.
