An Architecture for a Personalized Web of Active Documents

Abstract

This paper describes the design and implementation of an architecture to support discovery, advertizing and fusion of multimedia information on the Internet. The basic tenet of the proposed architecture is a metadata abstraction, referred to as adlet. Based on this abstraction, a document dynamically builds metadata, advertises itself to other active documents on the Internet, and eventually joins groups of documents of the same interest. The proposed architecture supports the creation and composition of adlets, and the negotiation and communications protocols required to manage adlet groups of common interests. The paper describes the implementation of the adlet architecture using Java, CORBA and XML technologies. A prototype is currenlty being developed for a testbed of active documents over wide area networks
