The Document Foundation (TDF), the non-profit entity behind LibreOffice, welcomes the inclusion of the Open Document Format (ODF) as a mandated standard format in Germany’s Deutschland-Stack, the federal government’s sovereign digital infrastructure framework for all public administrations. The Stack, published by the German Federal Ministry for Digital and State Modernisation (Bundesministerium für Digitales und Staatsmodernisierung), establishes the technical standards for a shared, interoperable and sovereign digital infrastructure serving all Germany’s public administrations. Under the framework’s “Semantic Technologies and Real-Time Analytics” pillar, ODF and PDF/UA are explicitly named as the two mandated document formats, to the exclusion of proprietary alternatives. “This is not a recommendation or a preference, it is a mandate,” said Florian Effenberger, Executive Director of The Document Foundation. “Germany’s decision to anchor ODF at the heart of its national sovereign stack confirms what we have argued for years: open, vendor-neutral document formats are not a niche concern for some technology specialists and FOSS advocates. They are a fundamental infrastructure for democratic, interoperable and sovereign public administrations.” The Deutschland-Stack is grounded in a set of principles that align with TDF’s long-standing advocacy positions. The framework adopts a “Made in EU first” principle, requires open interfaces and local data storage,
