The non-profit community improving U. S. reporting through a free, open standard
XBRL Taxonomy Development Handbook
The Taxonomy Development Handbook (TDH) is a comprehensive guide directing regulators, industry experts, and businesses through a practical roadmap to building high quality data standards, to support the increasing demand for data standardization in business and government reporting.
Point of View
DQC Rules are now available in the FASB US GAAP Taxonomy. Shouldn’t every SEC filer use them?
If the tool is there, if it is easy and inexpensive to use, why not use it? Starting this year, filers can review the most established rules generating the highest number of errors directly in the FASB’s US GAAP Financial Reporting Taxonomy. One more good reason to file quality XBRL data.
State and Local Government
This XBRL US working group seeks to address standards related to state and local government annual financial reports by designing schemas and XBRL implementation(s) for open data reporting of state and local government actual financial results.

Approved Validation Rules
The Data Quality Committee released version 11 of freely-available rules and guidance in February. These 53 rules are automated checks that help filers using US GAAP and IFRS Taxonomies supported by the US Securities and Exchange Commission detect and resolve inconsistencies or errors in XBRL-formatted financial data.
