XBRL is short for "extensible business reporting language" and it is part of the family of extensible markup languages (XML). The XBRL language enables you to communicate financial data in a way that saves both time and costs, according to xbrl.org. XBRL files come in two file types: XBRL instances and XBRL taxonomies. XBRL instances end with .xml , and XBRL taxonomies end with .xsd. You can view these files with the open source program, Dragon View.
