XS2OWL is a framework that expresses the semantics of XML Schema in OWL syntax to enable interoperability between the Semantic Web and XML repositories. It captures the semantics of XML Schema 1.1 constructs and uplifts schemas to OWL 2.0 syntax while allowing downlifting back to the original schema. The framework is based on the XS2OWL mapping model and implements the mappings as an XSLT stylesheet to represent identity constraints and support schemas following the XSD1.0/1.1 standards.
