Extend your Collection

A complete, automatic revision history for every Omeka S site page, with the ability to browse old versions, compare changes line by line, and restore any previous state with a single click.

Omeka S is fantastic for publishing digital collections. But if you’ve ever tried to run a content-driven site (especially a portfolio, research hub, or institutional site) you’ve probably felt the gap.

The module uses Retrieval-Augmented Generation (RAG) — a pattern that grounds AI responses in your actual content rather than the model's training data to help discoverability and increase usage of your collections.

Every digital collection is only as safe as its last backup. The Backup module for Omeka S was built to make that backup a reliable, repeatable, and fully self-contained operation - no extra server software required.
