【 摘 要 】

In order to support interoperability of learning tools and reusability of resources, this paper introduces a framework for harvesting learning objectsfrom web-based content. Therefore, commonly-known web technologies areexamined with respect to their suitability for harvesting embedded meta-data.Then, a lightweight application profile and a microformat for learning objectsare proposed based on well-known learning object metadata standards.Additionally, we describe a web service which utilizes XSL transformation(GRDDL) to extract learning objects from different web pages, and provide aSQI target as a retrieval facility using a more complex query language calledSPARQL. Finally, we outline the applicability of our framework on the basis ofa search client employing the new SQI service for searching and retrievinglearning objects.
