Abstract

One of the prominent characteristics of XML applications is their dynamic nature. When a system grows and evolves, old user requirements change and/or new requirements accumulate. Apart from changes in the interfaces used/provided by the system or its components, it is also necessary to modify the existing documents with each new version, so they are valid against the new specification. In this doctoral work we will extend an existing conceptual modeling approach with the support for multiple versions of the model. Thanks to this extension, it will be possible to detect changes between two versions of a schema and generate revalidation script for the existing data. By adding integrity constraints to the model, it will be able to revalidate changes in semantics besides changes in structure.
