Approved in February, 2019, two new rules in this release support Negative Values with IFRS Taxonomies and Extension Members for IFRS and US GAAP Taxonomies. Learn more about these rules and others maintained in this release from prior versions at

This fix release includes updates to address SEC FAST Act requirements relative to the 2018 UGT & IFRS Taxonomies, and the 2019 UGT

This fix release does not require users to update DQC Rules plugin installations from v8.1.3, unless you're processing the checks locally (without using the Internet). If you're using the plugin for the first time, install according to the instructions below.

Change logs, build details & unit test results:

To use DQC Rules with Arelle's graphic interface (GUI):

  1. Download and extract the source code .zip or tar.gz archive of this release to your local computer.

  2. Remove all prior DQC Rules plugin installations from Arelle (prior to May 20, 2019) This version includes new functionality, so any prior version of DQC rules / xule should be removed. The current build references noted above are found under the Tools->DQC->Version... menu - if your plugin reports different versions, go to Help->Manage Plugins menu. Select the existing xule (DQC) plugin and click on remove, close the Plugins menu and click "Yes" to allow the Arelle application to restart, then close Arelle.

  3. Delete existing and xule folder in Arelle's plugin folder and replace with files from this release. The plugin folder in the DQC release follows the plugin folder structure in Arelle. The file from the plugin\validate subfolder of the release should be dropped in the corresponding folder in the Arelle install. Likewise, the xule folder and files should be located at the plugin\xule folder in the Arelle install.

  4. Initialize the DQC plugin. After the files are copied from the release archive into the Arelle folder structure on the local computer, start Arelle and go to the Help->Manage Plugins menu. Click on the "Select" button, choose "" from the list and then click "OK" and "Yes" to restart Arelle. NOTE: It is not necessary to to select the "xule" plugin - the plugin imports the xule files automatically.

  5. Set the plugin to validate filings. After Arelle (re)starts, check that there is a check mark next to the DQC option under the Tools->Validation menu. If the DQC is not selected, click on the option to select it and it is now ready to run DQC checks when a filing is opened in Arelle.

  6. Use the Tools->DQC menu to update the Ruleset Map to the current version or manage changes to a customized Ruleset Map in the existing environment. See the README and Usage pages for more details and options.

To use DQC Rules from the command line:

Use --plugin validate/DQC on the command line. See Using DQC Rules with Arelle - from a command prompt for complete details.

About the DQC Rules Plugin

The DQC rules are run using an Arelle plugin written in an XBRL rule syntax called Xule. Xule is processed in a plugin for the SEC's EDGAR Renderer/Previewer - Arelle on a local computer or server. The DQC plugin reads a specified ruleset and the assertions defined in the ruleset are evaluated against an XBRL instance, a taxonomy or an extension taxonomy, creating validation messages.
