This illustrates once more how #OpenSource in #RulesAsCode can yield value beyond what was initially planned: from the initial use case of advising Members of Parliament on the budget of the State to supporting broader democratic debate with data!

🗳️ This weekend, 🇫🇷 votes for mayors… and OpenFisca-provided #OpenData is featured by @datagouvfr to help with decision-making!

The amounts of budget contributed by the national government to every city in France (“dotation globale de fonctionnement”) has been consolidated for years by the LexImpact team at the Assemblée nationale as parameters in the OpenFisca-France model, and is now available as an independent dataset.

Until November, solutions were only listed through aggregation of national portals. In the last quarter, the @European Commission decided to expand sourcing by identifying “standout solutions” that go way beyond national usage. We are proud to be part of the first cohort to be directly listed as a solution for EU-wide (and beyond!) interoperability for #RulesAsCode, alongside other widely recognised #DigitalCommons such as @decidim and @consuldemocracy.

🌟 OpenFisca is now featured as a “standout solution” in the 🇪🇺 #OpenSource Solutions Catalogue for interoperability!
https://interoperable-europe.ec.europa.eu/eu-oss-catalogue/solutions/openfisca-core
The EU OSS Catalogue, launched in March 2025 on the #InteroperableEurope Portal, showcases over 800 open source solutions developed or used by public administrations across Europe. It helps Member States implement the #InteroperableEuropeAct by sharing and reusing interoperability solutions.

This 5 min video explains how to restore data and pull requests that were erased and closed during the #ShaiHulud 2.0 #cyberattack, a necessary step to recover for a large community like @openfisca.
https://videos.lescommuns.org/w/uh4zBGQ2BmjHUoG3oJfQt4
After an immediate reaction to isolate and confine, we reviewed all access rights to decrease our attack surface. We are now focusing on supporting our global community in restoring data and cleaning up attack leftovers… and maybe help other #DigitalCommons along the way 🙂
