Query rewriting for open XML data integration systems

Résumé

This paper presents OpenXView, a model for open XML data integration systems, characterized by the autonomy of users that publish XML data on a common topic. Autonomy implies frequent and unpredictable changes to data and a high degree of structure heterogeneity. The OpenXView model provides an original integration schema, based on a hybrid ontology - XML schema structure. We propose solutions for two important problems in such systems: easy access to data through a simple query language over the common schema and simple integration view management when data changes. This paper focuses on the query rewriting problem in OpenXView, for which existing algorithms are not suitable, and proposes a query translation algorithm.
