Abstract
In this chapter we study the impact of XML schema evolution on related XML queries when the evolution can affect the result of those queries. We provide a novel approach and present preliminary solution to the problem. In our approach, we define changes in the schema and propagate these changes to the queries. We focus on a subset of XPath queries and show how particular changes in data structure can be propagated to them, either automatically or with user interference. The implementation of our approach is incorporated into a general evolution framework called DaemonX and it enables us to provide a proof of the concept.
