Abstract

XQuery has been widely considered as a mapping language for XML-based data sharing systems. Though many recent efforts have been made to provide automated support for constructing such semantic mappings between schemas, in practice it is inevitable for the user to directly construct or maintain the naive yet troublesome mapping expressions. In this paper, we propose the mapping combination framework for incrementally construct so called combined mappings, by starting with simple atomic ones and applying a set of combination operators. Different from the naive expressions, the combined mappings are extensible and maintainable, which gives flexibility and reusability in the process of mapping construction and maintenance, and alleviates the burden on the user in general cases.
