| Abstract | XML Schema is an XML schema language used mainly to describe the content model of an XML element. A content model usually specifies information about sub-elements and their relationships or structure. However, in real-world XML documents there are others kinds of information or relationships that need to be specified, e.g., the content value of an element is equal to the summation of those of some other elements. This kind of relationship is called a semantic constraint. This study first proposes a framework that can represent such semantic constraints by enhancing XML Schema. A technique is then developed to model an XML Schema with semantic constraints and validate an XML document against it. Finally, an electronic-form submission system with semantic constraint validation is designed and implemented in order to demonstrate the application and the usefulness of the proposed framework and technique. |
