A spatial approach for the access, manipulation and publication of digital library artifacts

Abstract: "Given the existence of a digital library, what software tools would be most efficient and effective in enhancing the educational value and usability of the collection?" The George Bush Digital Video Library project will address this question by developing a speech-based digital video library together with a set of network-based interactive tools that extend beyond search and retrieval operations. The goal of this project is to extend the functionality of the digital library to allow researchers, educators, and students to peruse, compose, and publish knowledge artifacts in the collection to meet their informational needs. Crucial to the realization of the project's objectives is the user interface. Drawing from current research as well as development experience with previous prototypes, this paper proposes and discusses a spatially oriented Web-based direct manipulation interface to the digital library. The interface is designed to integrate the various tasks envisioned to be performed by a patron, which include information retrieval and organization, as well as artifact authoring and publication. Patrons will be able to search the library for video clips and textual transcripts, integrate the desired information artifacts together with any annotations to dynamically form a synchronized mixed text and video hypermedia presentation through the material, and finally publish the presentation back into the digital library if desired.
