Stackable Data Platform for THE City OF FREIBURG

An IoT connected Smart City Data Platform

Background: In the city of Freiburg, Germany’s southernmost metropolis in the heart of the Black Forest, vast amounts of data flow every day – from traffic patterns and weather updates to climate data and waste volumes. But despite this treasure trove of information, harnessing its potential was proving to be a major challenge.

Challenge: The city of Freiburg aimed to modernize and integrate its data management. They needed a solution that would seamlessly connect disparate data sources and systems and simplify access for a wide range of users, from citizens to research institutes and businesses. Data security and privacy were key concerns as they sought to transform Freiburg into a data hub without compromising these critical aspects – all under the umbrella of the new DATEN:RAUM:FREIBURG initiative.

Solution: The intiative DATEN:RAUM:FREIBURG aligns seamlessly with the city’s digitization strategy and has secured substantial public funding of €8.3 million over five years, plus a €4.5 million own contribution. As one of Germany’s pioneering projects, DATEN:RAUM:FREIBURG is leading the way in creating a blueprint for other municipalities to follow. Collaboration with like-minded cities is already underway, with the aim of building knowledge and infrastructure that can be shared nationwide.

Stackable, as part of a consortium with Benz+Walter, Accso, IONOS, Yunex, is contributing its open source Stackable Data Platform as the foundation for this digital urban data initiative. Based on openness and accessibility, it paves the way for innovative, public-spirited smart city solutions.
