The NUS Digital Media Gallery ― A Dynamic Architecture for Audio, Image, Clipart, and Video Repository Accessible via the Campus Learning Management System and the Digital Library

摘要

This paper describes the development of a digital media gallery (DMG) that allows users to search, preview digital contents, and link them to the course website within the Integrated Virtual Learning Environment (IVLE). The IVLE is a web-based learning management system designed and developed by the Centre for Instructional Technology (CIT) at the National University of Singapore (NUS) to manage and support teaching and learning. The gallery is a joint collaboration between CIT and the NUS Library, applying a user oriented perspective to developing, organizing and using digital resources for teaching and research. The digital resources are broadly categorized into Audio, Video, Image and clipart. Within each grouping, the contents are classified and meta tagged according to the IMS specification. For video recordings, an interface developed by VIDTOOLS, a commercial company, was used to facilitate efficient navigation of video content via keyframe indexing, with a time slider to support quick skimming through the recording.
