Although XML and RDF are widely used languages for various Web applications, they lack capabilities for specification of axioms as well as complex rules and conditions, and thus do not have sufficient mechanisms to fulfill the goal of the Semantic Web. The proposed XML Declarative Description language, while employing XML as its bare syntax, can represent or encode all XML-based application markup languages. XDD enhances their expressive power by providing a simple mechanism to succinctly and uniformly express implicit information, axioms, rules, constraints, and conditions, in addition to explicit information expressible by normal XML and RDF frameworks. Because XDD has well-defined semantics, languages encoded in XDD can have their intended semantics formally defined without resorting to other formalisms.
