Research on XBRL Domain Ontology Construction

XBRL (eXtensible Business Reporting Language) as an application of XML (eXtensible Markup Language) technology in the field of business reporting, uses information technology to add tags for the financial reporting metadata, to achieve unstructured data processing effectively. At first, this paper analyzes the XBRL technology framework, finds out the concepts and relationships between them, and accordingly designs the XBRL domain ontology model, then based on the model we have proposed, we choose OWL DL ontology description language and Protégé3.4, take balance sheet as an example, and apply the XBRL ontology model to balance sheet to construct the taxonomy and instance, and thereby achieve the implementation of XBRL domain ontology construction. XBRL needs the integration of the accounting, engineering, computer, management and other disciplines, and the future research should be committed to solve the lack of semantic and reasoning mechanism to implement the further promotion and application of XBRL financial reporting.
