A method of performing XBRL extension taxonomy concept replacement includes analyzing, by a processor, an XBRL document having XBRL tags to identify an XBRL extension taxonomy concept of an XBRL extension taxonomy that is superfluous in comparison with an XBRL base taxonomy concept for an XBRL base taxonomy upon which the XBRL extension taxonomy is based. The processor is configured to identify an extension extended linkrole in the XBRL extension taxonomy that includes the identified XBRL extension taxonomy concept, determine a base extended linkrole in the XBRL base taxonomy that matches the extension extended linkrole, determine an XBRL base taxonomy concept in the base extended linkrole that matches the identified XBRL extension taxonomy concept, and replace the identified XBRL extension taxonomy concept with the XBRL base taxonomy concept in the base extended linkrole.
