  We propose to demonstrate LiquidXML, a platform for managing large corpora of
XML documents in large-scale P2P networks. All LiquidXML peers may publish XML
documents to be shared with all the network peers. The challenge then is to
efficiently (re-)distribute the published content in the network, possibly in
overlapping, redundant fragments, to support efficient processing of queries at
each peer. The novelty of LiquidXML relies in its adaptive method of choosing
which data fragments are stored where, to improve performance. The "liquid"
aspect of XML management is twofold: XML data flows from many sources towards
many consumers, and its distribution in the network continuously adapts to
improve query performance.
