Towards Interoperable Learning Object Repositories: The Ariadne Experience

In this paper, we present an approach for producing interoperable metadata by mapping metadata structures of application profiles into standard metadata structures. As a study case, we map the ARIADNE metadata structure into the LOM structure. We use XSLT to transform ARIADNE XML instances into IEEE LOM Instances. Finally, we validate the resulting LOM XML instances. The major contribution of this paper is that it explains how mapping and transforming metadata between different metadata specifications is not always a simple one-to-one process. We present and analyze different kinds of complications involved in such mappings. This work increases the interoperability between ARIADNE and other Learning Object Repositories that rely on IEEE LOM.
