Abstract :
Reusable learning objects (RLO) are used in different contexts and are accompanied by their associated metadata for searching, managing, etc. This paper presents an application framework for metadata sharing, searching and visualizing techniques in a peer-to-peer network. The framework considers the semantic meaning of the query and applies context based peer address mapping to search metadata. We have also presented an algorithm for grouping metadata. By using a car metaphor, the grouped information is visualized in a 3D virtual environment for intuitive navigation and browsing that intends to show the context and relationship among the displayed results
