In particular, it is necessary to keep the consistency between different software artifacts and XML documents when evolution tasks are carried out. In this paper we present an approach to evolve XML schemas and documents conceptually modeled by(More)

The strategy of evolution in which our architecture is based is that of 'forward database maintenance', that is, changes are applied to the conceptual schema and propagated automatically(More)

The existence of different kinds of models, at different levels of abstraction, involves the necessity of transferring knowledge from one model to another. This framework can also be applied in the context of metadata management for database(More)
