Abstract

The widespread use of XML brings new challenges for its integration into general software development processes. 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 means of UML class diagrams. Evolution primitives are issued on the UML class diagram and are automatically propagated down to the XML schema. The XML documents are also automatically modified to conform to the new XML schema. In this way, the consistency between the different artifacts involved is kept. This goal is achieved by using an intermediate component which reflects how the UML diagrams are translated into the XML schemas.
