Reusability Evaluation of Learning Objects Stored in Open Repositories Based on Their Metadata

Reusability is considered to be the key property of learning objects residing in open repositories. In consecuence, measurement instruments for learning object reusability should be developed. In this preliminary research we propose to evaluate the reusability of learning objects by a priori reusability analysis based on their metadata records. A set of reusability metrics extracted from metadata records are defined and a quality assessment of the metadata application profiles defined in repositories eLera and Merlot is exposed.
