Open Data in the Stockholm Region- is a collaborative project involving 26 municipalities in the Greater Stockholm region.
The aim of this project is to make municipal data available to private individuals and SMEs to increase its usage in order to drive new innovation and growth. The project is financed by the ERDF as well as the City of Stockholm and will run until the end of 2020.
The project team has developed processes and tools to support the municipalities, procured a common regional open data portal, collaborated closely with key representatives from the 26 municipalities, and had face-to-face meetings with nearly 50 companies and organizations to continuously gain new insights into the needs and requirements of open data.
