Abstract
In this paper we propose a mediator architecture for the querying and integration of Web-accessible XML data sources. Our contributions are (i) the definition of a simple but expressive mapping language, following the local as view approach and describing XML resources as local views of some global schema, and (ii) efficient algorithms for rewriting user queries according to existing source descriptions. The approach has been validated by the STYX prototype. © Springer-Verlag Berlin Heidelberg 2002.
