Data caching in data integration systems based on AXML technology

AXML (active XML) is a framework for peer-to-peer data integration from XML sources. In AXML documents data can be presented extensionally or intentionally by including calls to local or remote Web services. In complex AXML-based systems data retrieval can be inefficient. In the paper we propose a caching mechanism for systems based on active XML. We show how it can influence network communication and data integration processes.
