- Active development in the field of e-Learning has led to multiple organizations and specifications that try to provide some interoperability to systems, tools and learning contents. The great amount of specifications, exacerbated by its intrinsic complexity, has resulted in many commercial tools that agree specific norms or even subsets of one specification. Therefore, few actual systems have implemented proposed reference models. This paper exposes the experience from the University of Alcala TIFyC research group that, through several years and research, has developed an e-Learning applications' set which conforms current specifications and which implements one of the existing reference models, namely the IMS Global Learning Consortium reference model.
