Personalization, adaptation and recommendation are central aims of Technology Enhanced Learning (TEL) environments. In this paper, information retrieval and clustering techniques are more and more often applied to filter and deliver learning resources according to user preferences and requirements. However, the suitability and scope of possible recommendations is fundamentally dependent on the available data, such as metadata about learning resources as well as users. However, quantity and quality of both is still limited. On the other hand, throughout the last years, the Linked Data (LD) movement has succeeded to provide a vast body of well-interlinked and publicly accessible web data.
