The Open Source Software Input Output Tables (OSSIO) provide global input-output tables of open-source software flows between countries. The tables cover five programming languages and 15 countries. They are constructed by mapping the geographic locations of software developers and the dependency linkages between software projects, aggregating these into flows between countries.
The dataset was created as part of the EU Horizon Europe project RETHINK-GSC, which studies knowledge flows in global supply chains.
