2020 Taxonomy Support

EDGAR was updated to support the following new taxonomies:

• US GAAP 2020 Taxonomy
• SEC Reporting 2020 Taxonomy
• COUNTRY 2020 Taxonomy
• CURRENCY 2020 Taxonomy
• EXCH 2020 Taxonomy
• SIC 2020 Taxonomy

Additionally, support for the 2012 and 2013 INVEST taxonomies was removed.

Filing-Specific Taxonomy Concepts

EDGAR Interactive Data submissions now permit filers to annotate their filing-specific custom XBRL taxonomy concepts using links to “anchoring” concepts in EDGAR standard XBRL taxonomies.

Version 5.3a of the GoFiler family addresses these changes to EDGAR. If you need to update your version of GoFiler, use the Check for Updates function within your software. For a full list of improvements that were made for Version 5.3a, please refer to the software release notes.
