| Abstract: | XML is emerging as the dominant standard for data representation and exchange over the Web. This paper extends XML RL which is a rule based XML query language based on higher level data model, with some important object oriented features such as element hierarchy, multiple inheritance, polymorphism. The paper first extend the XML RL data model with element hierarchy, multiple inheritance and polymorphism. Then it extend XML RL to support polymorphic element and reference as well as exclusive element and reference. |
