Omeka: sovereignty score and 8 European alternatives

Omeka is an open-source platform that lets museums, archives, libraries and research projects publish digital collections and build online exhibits. Omeka S is designed for institutions that share one pool of resources across several websites, and supports linked open data, themes and modules. Omeka Classic is aimed at individual projects and educators. Both versions are installed on a web server of the user's choice. Those who prefer not to run their own installation can use the hosted service Omeka.net.

Omeka is developed by the Corporation for Digital Scholarship, which operates as Digital Scholar, a non-profit with an office in Falls Church, Virginia. The software is released under the GNU General Public License version 3, so European organisations can download, inspect and run it on their own infrastructure. Omeka.net is operated from offices in the United States, and its terms of service do not name a fixed storage location for data. A European institution that manages sensitive collections can therefore choose self-hosting, which keeps the data under its own control.

Why digital sovereignty matters with Omeka

Omeka is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Omeka hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Omeka is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Omeka together with your other vendors and gives a total score, a heatmap and the main risk drivers.
