digital_asset_inventory

The Digital Asset Inventory (DAI) module helps site administrators gain visibility into digital assets on their Drupal site. It scans managed files, media, manual uploads, and external URLs, tracking where assets are referenced across content. Orphaned and unused assets are identified so teams can filter results, export reports, and coordinate removal with asset owners.

The module includes a dual-purpose archival management system designed to support ADA Title II compliance efforts. Legacy archives classify pre-deadline content eligible for WCAG 2.1 AA considerations, while general archives retain content for reference without exemption claims. Archived files are tracked with SHA-256 checksums, archive status is automatically voided if content is modified, and permanent audit records are maintained for compliance reviews.

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.

Developed and maintained by The Regents of the University of California.
