Abstract
XML schema mapping is a fundamental issue in XML integration and exchange. Existing studies often follow the approach of relational schema mapping to present XML mapping as correspondences between and constraints on tuples of elements. However, XML mappings involving hierarchical and heterogeneous data are often complex to present with this approach. In this paper, we propose a new approach named Conjunctive-Disjunctive View (CDV) for XML schema mapping. A CDV is a pattern-based view which allows disjunctive as well as conjunctive composition of data elements. It can conveniently present complex mapping requests involving hierarchical, heterogeneous and even recursive data. We describe the design issues and the features of CDV, with certain typical examples of XML schema mappings.
