Redesigning the Web: from passive pages to coordinated agents in PageSpaces

Currently, the Web does not support distributed applications well. Existing approaches are oriented towards centralized applications at servers, or local programs within clients. To overcome this deficit, the PageSpace platform was designed for distributed, coordinated agents in the Web. We take a specific approach to coordinate agents in PageSpace applications, namely variants of coordination language Linda that support rules and services to guide their cooperation. This technology is integrated with the standard Web technology and the language Java. Several kinds of agents live in the PageSpace: user interface agents, personal home agents, the agents that implement applications, and the kernel agents of the platform. Within the architecture it is possible to support fault tolerance and mobile agents as well.
