Title:
Supporting The Web: A Distributed Hyperlink Database System
Authors:
James E. Pitkow
R. Kipp Jones
Abstract:
In our last paper [Pitkow & Jones 1995], we presented an integrated
scheme for an intelligent publishing environment that included a
locally maintained hyperlink database. This paper takes our previous
work full cycle by extending the scope of the hyperlink database to
include the entire Web. While the notion of hyperlink databases has
been around since the beginnings of hypertext, the Web provides the
opportunity to experiment with the largest open distributed hypertext
system. The addition of hyperlink databases to the Web infrastructure
positively impacts several areas including: referential integrity,
link maintenance, navigation and visualization. This paper presents
an architecture and migration path for the deployment of a scalable
hyperlink database server called Atlas. Atlas is designed to be scalable,
autonomous, and weakly consistent. After introducing the concept and
utility of link databases, this paper discusses the Atlas architecture
and functionality. We conclude with a discussion of subscriber and
publisher policies that exploit the underlying hyperlink infrastructure
and intelligent publishing environments.
