Germany has strictly standardized its digital document requirements. The Deutschland-Stack (in Deutsch), the country's new sovereign digital infrastructure framework, names just two document formats that public administrations are allowed to use: ODF and PDF/UA.
Proprietary document formats from Microsoft like .doc, .ppt, and .xls are not included.
What's happening?
The framework is published by Germany's Federal Ministry for Digital Transformation and Government Modernisation, and it covers every level of public administration in the country, from federal government bodies down to states and municipalities.
Also keep in mind that the rollout of key infrastructure components is targeted for 2028.
ODF, or OpenDocument Format, is an XML-based file format for office documents. It covers text files, spreadsheets, charts, and graphical documents. The standard is maintained by OASIS and is also an ISO standard (ISO/IEC 26300), which means it is vendor-neutral and not controlled by any single company.
PDF/UA, short for PDF/Universal Accessibility, is the ISO accessibility standard for PDF files (ISO 14289). It lays out specs that make PDF documents readable by assistive technologies like screen readers, making it a sensible choice for a government that has to serve a diverse population.
The reasons behind this are not hard to understand. Vendor lock-in is the obvious one.
When public administrations run on proprietary document formats, they end up dependent on the vendor that controls those formats, with no real way out without significant disruption and cost.
The Deutschland-Stack explicitly calls this out, with reducing lock-in effects listed as one of its core goals. The framework also prioritizes use of open source solutions where possible, and explicitly favors sourcing from European providers over foreign alternatives.
Speaking on the subject, Florian Effenberger, Executive Director of The Document Foundation, stated that:
This is not a recommendation or a preference, it is a mandate. 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.
Closing Words
Moves like this take time to matter, but they do matter. Governments adopting open standards at this scale sends a clear signal about where things are heading, and it makes the case for interoperable, vendor-neutral infrastructure in a way that no amount of social media preaching can.
Germany doing this in a binding, nationwide framework is a meaningful step, and the rest of Europe would benefit if they took note of this.
