Generalized Model for Interoperability of Data Based on Model Driven Architecture

In the recent years, e-learning gained popularity among educational institutions as well as enterprises. As the result of that many commercial or open-source Learning Management Systems (LMS) were developed to manage online courses. While the usage of these systems gains recognition and acceptance amongst institutions, there are new problems arising that need to be solved. Because of multiplicity of platforms and approaches used for various systems implementation, it becomes increasingly difficult to exchange pieces of information among those systems. Applications and their data become isolated what is a clear economical concern for the future of these technologies. The present study describes a method, based on Model Driven Architecture (MDA), for integrating approaches of candidate LMS systems into a generalized architectural framework. The framework makes use of standards for description of data and metadata like learning materials (IEEE LOM, IEEE PAPI), student information (IMS LIP) or learning design (IMS LD). This platform-independent framework can be used for an automatic migration of data between various elearning platforms.
