Abstract: Due to lack of sufficient semantic information, it is difficult to interoperate among XML data files with different schemas. Facing the needs to integrate XML data in the field of Well-Engineering, this paper proposes a model-independent semantic integration method for XML data using domain global ontology. This method builds semantic mapping between domain ontology and paths of XML schema to shielding the pattern differences; then, XML data is stored as relational data using model-mapping method; finally, the SPARQL query will be rewriting into SQL statements to realize semantic query. By semantic annotating to XML schema and using relational database to store and query XML date, this method solves the semantic integration for domain XML data effectively.
