Pharos: a scalable distributed architecture for locating heterogeneous information sources |
Abstract | ||
---|---|---|
Pharos is a .sca&zble distributed architecture for locating het- erogeneous informatdon sources. !7he system incorporates a hierarcfiical metaduta structure into a multi-level rettieval system. Queries are resolved through an iterative decision- making process. The first step retrieves coarse-grain meta- data, about all sources, stored on iocal, mastively replicated, high-level servers. Further steps retrieve more detailed mata- data, about a greatly reduced set of souwes, stored on re- mote, sparsety 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 soumes over the Internet. |
