Mapping Discovery for XML Data Integration

Mapping Discovery for XML Data Integration
Abstract. The interoperability of heterogeneous data sources is an important issue in many applications such as mediation systems or web-based systems. In these systems, each data source exports a schema and each application defines a target schema representing its needs. The way instances of the target schema are derived from the sources is described through mappings. Generating such mappings is a difficult task, especially when the schemas are semi structured. In this paper, we propose an approach for mapping generation in an XML context; the basic idea is to decompose the target schema into subtrees and to find mappings, called partial mappings, for each of them; the mappings for the whole target schema are then produced by combining the partial mappings and checking that the structure of the target schema is preserved. We also present a tool supporting our approach and some experimental results.
