Inventaire: sovereignty score and 8 European alternatives

Inventaire is a free-software social network for listing and sharing books. Individuals and groups build networks of librarians around the books they own. The network runs on an open bibliographic database that extends Wikidata, so book data is available as open data. Inventaire is offered as a web application at inventaire.io; you can also install the server and client code yourself.

Inventaire is managed by a French non-profit association (association loi 1901) that looks after the inventaire.io instance, its data and its code. The code is open source under the GNU AGPL-3.0. According to the project's legal notice, inventaire.io is hosted with providers in Germany, France and Switzerland. The project is working on splitting Inventaire into two linked parts, the social network and the bibliographic database, so that more instances can reuse the same book data. Development was co-funded through NLnet and the European Union's NGI Zero programme.

Why digital sovereignty matters with Inventaire

Inventaire is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Inventaire hosts data in the EU and in Switzerland. Switzerland is covered by a European Commission adequacy decision, so personal data can go there without extra safeguards. If you require strictly EU hosting, check the data processing agreement for which data is stored in Switzerland.

Inventaire 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 Inventaire together with your other vendors and gives a total score, a heatmap and the main risk drivers.
