Design and implementation of a distributed learning resource registry system

This paper illustrated the design and implementation of a distributed learning resource registry system. This system faces the challenge that e-learning users can hardly find out their interested learning resources in current distributed and relatively isolated environment where web-based learning contents are stored in different resource repositories or management systems. This paper also depicts the Distributed Learning Resource Registry and Discovery Model, which the implemented system is based on. Our system enables developers and repository systems to register learning resources to the registry system and provides a discovery mechanism to find required learning resources. We argue that it can realize the integration of different learning resource repository or management systems in a loose-coupled manner by utilizing web service technology and build a distributed virtual learning resource marketplace.
