Abstract: Using a scoring system, this paper provides a
comparative assessment of the quality of data between XBRL
formatted financial reports and non-XBRL financial reports. It shows a
major improvement in the quality of data of XBRL formatted financial
reports. Although XBRL formatted financial reports do not show
much advantage in the quality at the beginning, XBRL financial
reports lately display a large improvement in the quality of data in
almost all aspects. With the improved XBRL web data managing,
presentation and analysis applications, XBRL formatted financial
reports have a much better accessibility, are more accurate and better
in timeliness.
