psiX: Hierarchical Distributed Index for Efficiently Locating XML Data in Peer-to-Peer Networks

Overview One of the most important challenges in a Peer-to-Peer (P2P) network is to efficiently locate relevant data sources across a large number of participating peers. With the increasing popularity of the eXtensible Markup Language (XML) as a standard for information interchange on the Internet, XML is commonly used as an underlying data model for P2P applications to deal with the heterogeneity of data and to enhance the expressiveness of queries. To address the problem of efficiently locating relevant XML documents in the P2P networks, a new system called psiX is developed that runs on top of an existing distributed hashing framework. Under the psiX system, each XML document is mapped into an algebraic signature that captures the structural summary of the document.
