A REGISTRY BASED DISCOVERY MECHANISM FOR E-LEARNING WEB SERVICES

Abstract

E-learning is currently taking the shape of a Web Service in various applications i.e. learners
 can search for suitable content, book it, pay for it and consume it. This paper shows how the
 search aspects for e-learning content can technically be combined with the recent
 standardization efforts that aim at content exchangeability and efficient reuse. A repository for
 learning object publication and search is proposed that essentially adapts the UDDI framework
 used in commercial Web Services to the e-learning context. To adopt Web Services technology
 towards the reusability and aggregation of e-learning services, the conceptual Web Services
 architecture and its building blocks need to be augmented. The objective of this research is to
 design broker based registry architecture for e- Web services which facilitates effective elearning
 content/service discovery for the consumption or composition. The implementation
 followed by experimentation showed that, the proposed e-learning discovery architecture
 facilitates effective discovery with moderate performance in terms of overall response.
