A Proposal of Separation of Concerns in EMLs and Its Relation with LD

This paper deals with a separation of concerns proposal for Educational Modeling Languages (EMLs). Basically, it proposes to structure these languages in a way different from the one proposed by the IMS Learning Design (LD) specification, currently considered as the standard EML. We assume that the LD specification is very complex and it is difficult to develop design and runtime applications and to produce EML-educational materials. Therefore, our goal is to simplify the LD specification. The main idea is not to attain the modeling of educational materials as a whole problem, but to divide it in several separated parts that could be solved in a step by step way. We propose two different kinds of parts: perspectives and aspects.
