Research and Development of a XML Modeling Tool

The XML schema is used to describe the structure and constraint of XML instance document. The designers of XML are required to proficiently use the schema definition language to write XML schema. In the development of large and medium XML schema, direct writing XML schema is difficult, which entails appropriate design tools to improve the development efficiency. A XML modeling tool dedicated to development of XML schema is designed and implemented based on MetaEdit+ meta-modeling tool. The designer uses this tool to first establish the XML conceptual model, and then transform the XML conceptual model to XML Schema. An instance is used to introduce the application method of this tool. Verification shows that the automatically generated XML Schema document is syntactically correct.
