Mission Statement of Team: The Team's research is focused on a number of issues pertaining to the architecture of digital libraries including resource discovery, extensible data store, and the implications of building a geographically referenced database. In relation to geographically referenced databases, issues under investigation include multi-dimensional indexing, data placement, tertiary storage, content-based retrieval, and performance tuning.
The team published a paper in the IEEE sponsored 3rd Annual Forum for the Research and Technology Advances in Digital Libraries [5]. This paper presents a summary of the research work, in particular it discusses scalable methods for locating information at different levels within a distributed digital library environment. Starting at the high level, the paper discusses how queries can be routed to appropriate information sources. At a given source, efficient query processing is supported by using materialized views and multidimensional index structures. Finally, efficient solutions are discussed to the problem of storage and retrieval of large objects on both secondary and tertiary storage devices.
