In parallel with emphasizing more transparency and social responsibility of businesses, usage rate of XBRL, a XML-based language specific to business reporting, is rapidly increasing. XBRL takes the same approach with the standardization of B2B electronic documents in that it defines components (concepts and their structures) of business reporting documents using XSD(XML Schema Definition). However, it is fundamentally different from the standardization of B2B electronic documents because it restricts concepts to specific types and it defines diverse relationship types for connecting the concepts to themselves and other additional information. As XBRL applications are getting activated, one hot issue is the necessity for standardization of XBRL documents in the national level and reusing the components systematically This paper proposes an alternative based on the problem analysis in order to make it possible to standardize and reuse XBRL documents systematically by applying the UN/CEFACT Core Component methodology.
