Conceptual XML Schema Evolution - the CoDEX Approach for Design and Redesign.

Abstract

Most available approaches for XML schema evolution specify the evolution steps for an XML schema or a DTD. This article will show that schema evolution can also be realized on a conceptual model. Schema evolution always requires propagating the changes to the XML documents that are already associated to the schema. This article suggests a method for conceptual schema evolution concerning all these subtasks. It is implemented in a tool called CoDEX (Conceptual Design and Evolution of XML schemas).
