Abstract

Pharos is a scalable distributed architecture for locating heterogeneous information sources. The system incorporates a hierarchical metadata structure into a multi-level retrieval system. Queries are resolved through an iterative decision-making process. The first step retrieves coarse-grain metadata, about all sources, stored on local, massively replicated, high-level servers. Further steps retrieve more detailed metadata, about a greatly reduced set of sources, stored on remote, sparsely replicated, topic-based mid-level servers. We present results of a simulation which indicate the feasibility of the architecture. We describe the structure, distribution, and retrieval of the metadata in Pharos to enable users to locate desirable information sources over the Internet.
