Application ID: 14469286

Base Claim:
1. An XBRL taxonomy migration system comprising: a processor having a memory that stores a program executable by the processor for performing a method of XBRL taxonomy migration; an XBRL taxonomy module including a first version of a first XBRL taxonomy having XBRL concepts and a second version of the first XBRL taxonomy having related XBRL concepts, each of the first version of the first XBRL taxonomy and the second version of the first XBRL taxonomy including a base taxonomy and optionally one or more extensions of the base taxonomy; and an automated taxonomy migration module that receives an XBRL document having XBRL tags of the first version of the first XBRL taxonomy and migrates the received XBRL document to the second version of the first XBRL taxonomy by replacing XBRL concepts of the first version of the first XBRL taxonomy in the received XBRL document with XBRL concepts of the second version of the first XBRL taxonomy, wherein the migrated XBRL document no longer uses the first version of the first XBRL taxonomy, wherein the automated taxonomy migration module maintains tags from the received XBRL document that are of a second XBRL taxonomy in the migrated XBRL document, the second XBRL taxonomy being different from the first XBRL taxonomy and tags of the second XBRL taxonomy being simultaneously included with the XBRL tags of the first XBRL taxonomy in the received XBRL document.

Claim 4:
4. The XBRL taxonomy migration system of claim 1 , further comprising an automated matching XBRL concept replacement module that: detects dependencies in calculations in the received XBRL document using the XBRL concepts in the received XBRL document; when dependencies are detected, determines whether a balance type of the first version XBRL taxonomy concept matches a balance type of a related second version XBRL taxonomy concept; when the balance type of the first version XBRL taxonomy concept matches the balance type of the related second version XBRL taxonomy concept, replaces the first version XBRL taxonomy concept in the received XBRL document with the related second version XBRL taxonomy concept of the matched balance type; and when the balance type of the first version XBRL taxonomy concept does not match the balance type of the related second version XBRL taxonomy concept, adjusts a weight of an arc using the related second version XBRL taxonomy concept in a calculation assertion when replacing the first version XBRL taxonomy concept in the received XBRL document with the related second version XBRL taxonomy concept.
