Berlin Open Source Strategy

The Berlin Open Source Strategy is a pioneering policy framework aimed at enhancing digital sovereignty and reducing reliance on proprietary software within the public administration of Berlin. Published by the Berlin Senate, this strategy delineates principles, goals, and specific actions for promoting open-source software (OSS) usage across the city-state's government operations. It has been recognized as a leading example of municipal commitment to open-source technology in Europe.

Historically, Berlin's public administration has depended heavily on proprietary software, particularly from major vendors like Microsoft. This dependency poses various risks, such as vendor lock-in, high licensing fees, and limited customization capabilities, raising concerns about data sovereignty when sensitive public data is managed by non-European companies. In light of geopolitical tensions and security uncertainties, the Berlin Senate has framed the adoption of open-source software not just as a cost-saving initiative, but as a strategic necessity to safeguard the city’s digital infrastructure.

The strategy is built on several foundational principles, including the concept of "Public Money, Public Code," which advocates that software developed with public funds should be made publicly available as open-source. Other principles emphasize digital sovereignty, interoperability, transparency, and innovation through collaboration between public administrations and the tech community.

A primary goal of the Berlin Open Source Strategy is to systematically reduce the city’s reliance on proprietary software for essential administrative functions such as productivity tools and communication systems. The strategy encourages changes to IT procurement practices to favor open-source solutions, thereby updating procurement criteria to include assessments of vendor independence and code availability. Furthermore, the strategy emphasizes the importance of building internal expertise by training staff within the administration to ensure a comprehensive understanding of open-source software benefits.

Berlin is committed to collaborating with other cities in Germany and Europe on shared open-source solutions, reinforcing the belief that investments in public software should yield benefits for the wider community. This collaboration is supported by organizations such as the Open Source Business Alliance and the Foundation for Public Code.

Recognizing the economic potential of a robust local open-source ecosystem, the strategy aims to stimulate value creation and support technology companies working with open-source solutions.

The Open Source Strategy aligns with Berlin's broader smart city and digitalization strategy, known as Gemeinsam Digital: Berlin, which promotes principles of openness and transparency. It also collaborates with CityLAB Berlin, the city's public innovation lab, to develop digital solutions that address urban challenges using open-source methodologies.

The strategy's implementation is supported by key institutional actors, including the Berlin Senate Chancellery, ITDZ Berlin (the city’s central IT service provider), CityLAB Berlin, and the Fraunhofer FOKUS research institute. 🇪🇺 European Context Berlin's open-source initiative reflects a broader European trend towards digital sovereignty and public administration modernization through open-source adoption. The European Commission and several European countries, including France and Spain, have initiated similar open-source policies, further emphasizing the movement's significance in shaping a sustainable digital ecosystem across the continent.

The Berlin Open Source Strategy serves as a crucial case study for smart city practitioners, demonstrating that open-source technology impacts not only technical choices but also broader issues of sovereignty, security, and democratic governance in urban development.
