The ITA project is aiming at achieving the convergence of the XBRL frameworks of the IFRS, EDINET and the U.S. GAAP Taxonomies. It is hoped that this architectural convergence will support the analysis and comparison of financial data reported in XBRL format, by enabling software vendors to develop applications for IFRS, Japanese GAAP and U.S. GAAP reporting based on a single XBRL architecture. 

By creating a single set of filing rules for XBRL filings, the Global Filing Manual will further support this convergence, and thereby improve the provision and comparability of financial information for markets that currently represent more than 85% of worldwide market capitalization. It is also hoped that the Global Filing Manual will be adopted by other regulators and users of the IFRS Taxonomy and that the rules will be applied to all related XBRL filings.
