Interoperability of XML schema applications with owl domain knowledge and semantic web toolsInteroperability of XML schema applications with owl domain knowledge and semantic web tools Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-10-042007enSeveral standards are expressed using XML Schema syntax, since the XML is the default standard for data exchange in the Internet. However, several applications need semantic support offered by domain ontologies and semantic Web tools like logic-based reasoners. Thus, there is a strong need for interoperability between XML Schema and OWL. This can be achieved if the XML schema constructs are expressed in OWL, where the enrichment with OWL domain ontologies and further semantic processing are possible. After semantic processing, the derived OWL constructs should be converted back to instances of the original schema. We present in this paper XS2OWL, a model and a sys-tem that allow the transformation of XML Schemas to OWL-DL constructs. These constructs can be used to drive the automatic creation of OWL domain ontologies and individuals. The XS2OWL transformation model allows the cor-rect conversion of the derived knowledge from OWL-DL back to XML con-structs valid according to the original XML Schemas, in order to be used trans-parently by the applications that follow XML Schema syntax of the standards.http://creativecommons.org/licenses/by/4.0/850-869In the proceedings of the 6th International Conference on Ontologies, DataBases, and Applications of Semantics Christodoulakis Stavros Χριστοδουλακης Σταυρος Chrisa Tsinaraki Springer Verlag XS2OWL Model
