Abstract

The interoperability between systems and the reusability of the stored and managed information is a key issue when designing an educational metadata management system. In this paper we present a schema-mapping algorithm that is capable of transforming the metadata description of an educational object created using specific metadata specification to a representation of the same object using either another specification , or the same specification in another language. We show that using advanced conversion techniques such as the proposed algorithm can result in lower standardization efforts. Simulation results over a wide range of learning objects demonstrate that the proposed algorithm except from requiring less human intervention, can handle real case mapping problems between not only different metadata models but also between models that use different standards for data representation.
