This tool allows you to compare two DTSs (Two XBRL Taxonomies) and generate a versioning report. That report could be used by mapping tools to migrate the mappings to a new taxonomy version and reduce the amount of work needed to implement the changes.
Versioning will reduce the time between a change in the reporting requirements is detected by regulators and the regulated entities starts producing reports according to the new requirements. The reduction of the time in this situation is a benefit in the quality of the regulation process and a guarantee to investors and analysts.
