Analysis and Validation of Learning Technology Models, Standards and Specifications: The Reference Model Analysis Grid (RMAG)

Abstract

The paper presents a model for the analysis, comparison and validation of standards, specifications and in particular reference models in the field of Technology Enhanced Learning TEL. The Reference Model Analysis Grid RMAG establishes categories of reference models and standards. Based on those categories, a set of criteria for the analysis and validation of standards was elaborated as a part of the ICOPER project that aims at interoperable open content for competency-based TEL. The analysis of standards in this context is targeted at developing a set of validated approaches that lead to a new reference model. Four standards were investigated, taking into account a broad range of aspects like practical and semantic interoperability and integration issues. In the case study, the authors analyzed both, the standards and specifications and the usefulness of the RMAG. The results of this case study can be used for further analyses of TEL standards as well as for reference models targeted at interoperability.
