Scalable access within the context of digital libraries

Abstract.

This paper presents a summary of some of the work-in-progress within the Alexandria Digital Library Project. In particular, we present scalable methods for locating information at different levels within a distributed digital library environment. Starting at the high level, we show 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, we propose solutions to the problem of storage and retrieval of large objects on both secondary and tertiary storage devices.
