Providing services by integrating information available in heterogeneous data sources is one of the targets of a mediation architecture. In the web context, sources may be non cooperative and be sometimes not available. Then, views are materialized in order to allow data access. When an update occurs on underlying data sources, the view must be maintained. Accordingly, we propose an approach for maintaining XML views in this context. The first step of our approach consists in detecting and identifying source updates, and the second step consists in the maintenance process itself. Our work is based upon an extension of the XAlgebra which annotates data with identifiers and upon a process of partial recovery of underlying sources.
