Abstract

The problem that “XML formally governs syntax only – not semantics” has been a serious barrier for XML-based data integration and the extension of current Web to Semantic Web. To address this problem, we propose the XML Semantics Definition Language(XSDL) to express XML author's intended meaning and propose a model-theoretic semantics for XML. Consequently, XML becomes a sub-language of RDF in expressiveness and XML data can be semantics-preserving transformed into RDF data. We further discuss the semantic entailment and validity of the XML documents.
