Making LOD of XBRL Data and Company Codes

Abstract

The eXtensible Business Reporting Language (XBRL for short) is an international standardized reporting language based on XML in financial affairs. In Japan, diverse dialects of XBRL is utilized as EDINET by Japanese Financial Services Agency, as TDnet by Tokyo Stock Exchange, etc. The infusion of Linked Data into XBRL enables us not only to promote the synergy among these data in respective XBRLs, but also to link such financial data to non-financial Linked Data, i.e, industrial statistics, energy statics, economic census, etc. However, EDINET and TDnet use their own company codes, which are different from each other. Therefore, we also made Linked Data of company codes in order to link respective data mutually, using the legal personality registration codes to Ministry of Justice so that a registration code mediates between a relevant EDINET code and a TDnet code. The Linked Data technology is available to unify diverse aspects of company activities.
