Semantic Adaptation of Schema Mappings When Schemas Evolve

Overview: Schemas evolve over time to accommodate the changes in the information they represent. Such evolution causes invalidation of various artifacts depending on the schemas, such as schema mappings. In this paper, the researchers study the semantics of mapping composition in the context of mapping adaptation and compare researchers approach with the incremental approach of Velegrakis et al. It is shown that their method is superior in terms of capturing the semantics of both the original mappings and the evolution.
