This chapter demonstrates that standardization is a very important subject in an e-learning context. Many e-learning systems and resources have emerged during the last decade. Thereby often economical as well as technical problems became significant due to missing standards. Economical reasons (e.g., high costs for producing learning material) often demand for reusability of learning resources. This in turn immediately requests for technical aspects like interoperability between systems of different vendors and discoverability of learning content. For this reason a multiplicity of initiatives have been started to define standards in different e-learning areas (e.g., learning content, learning processes, students΄ data, and repositories) in the past. Based on the fundamental concept of learning objects, this chapter describes many of these standardization efforts, their correlations, and the main actors in detail. [ABSTRACT FROM AUTHOR] |
