Digital Asset Inventory

The Digital Asset Inventory (DAI) module provides visibility into the digital assets used across a Drupal site. It scans managed files, media, server uploads, and references to external documents or resources, tracking where those assets appear in site content. It also identifies orphaned and unused assets so results can be filtered, reports exported, and cleanup coordinated with asset owners.

The module also includes a dual archive management system that supports ADA Title II compliance efforts. It provides structured workflows for classifying and tracking archived assets while maintaining audit records for documentation and review.

See the User Guide for documentation and FAQs.

Disclaimer

This module is a content governance and asset management tool, not an accessibility remediation system. It does not make content accessible or remediate WCAG issues. It supports compliance efforts by helping teams manage digital asset lifecycle decisions and apply consistent archiving practices with appropriate disclosure and audit trails.

Post-Installation

After enabling the module:

1. Navigate to People > Permissions and assign roles. The module provides six granular permissions: View, Scan, Delete, Archive, View Archives (read-only), and Administer.

3. Review results using the built-in filters to identify orphaned, missing, or unused assets.
4. Export CSV reports from the inventory page for offline review or coordination with content owners.
5. To configure archive features, go to /admin/config/accessibility/digital-asset-inventory. The archive system is off by default and can be enabled when ready.
6. The visual dashboard is at /admin/digital-asset-inventory/dashboard.
7. The public Archive Registry, if enabled, is at /archive-registry.
