Abstract
We have proposed a methodology for integrating local XML Schemas in [12]. An integrated global schema forms the basis for querying a set of local XML documents. In this paper, we discuss various strategies for rewriting the global query over the global schema into the sub-queries over local schemas. Their respective local schemas validate the sub-queries over the local XML documents. This requires the identification and use of mapping rules and relationships between the local schemas
