Abstract

An electronic document may provide more information than its paper-based counter part. For example, in addition to text and images, a scientific document may consist of either the rawdata or software that substantiates its hypothesis, ontology of its terms, a detailed comparison with its relatedwork, etc. In this study, we explore: a) an environment that represents a document as a Web Service, and b) two alternative frameworks that facilitate discovery and retrieval of documents, namely, Jini and UDDI. We describe how each framework supports documents that reside on a cluster of nodes. These nodes might be dispersed across the Internet or in geographical proximity using an Intranet setting. In addition to detailing discovery and retrieval of documents, we describe how each framework supports data availability in the presence of load imbalance and node failures. One finding of this study is that these two frameworks are complementary and can be used in conjunction with one another.
