For technology-enhanced learning, the idea of "learning objects" transfers the technologies of content management, methods of software engineering and principles of open access to educational resources. This paper reports on CampusContent, a research project and competence centre for e-learning at FernUniversitat in Hagen that designed and developed an integrated portal to a repository network named "edu-sharing." This portal facilitates sharing, joint development and reuse of learning material and pedagogical knowledge. CampusContent focused on essential challenges concerning use and utility of learning objects and developed principles, methods and tools that support educators in the process of contextualising learning objects within educational settings. Our model offers three levels of contextualisation: "configurable objects," "learning scenarios" and an "integrated work environment for educators."
