eXtensible Business Reporting Language (XBRL): Not Just a Good Idea; It's the Law

Published: 15 September 2010

ID: G00206964

Analyst(s): Joe Maguire

Summary

The future of eXtensible Business Reporting Language (XBRL) is secure because many companies are required by law to use it for financial reporting. After XBRL permeates the financial-reporting landscape, companies will employ it in other areas, including reporting about non-financial data and as a data format for system integration. Although XBRL uses Extensible Markup Language (XML) as a foundation, it is more complex than XML; XML expertise does not suffice for XBRL mastery. In this assessment, Gartner Research Director Joe Maguire discusses XBRL, its building blocks, its relationship to financial reporting, its other uses, and its strengths and weaknesses.
