This document summarizes the experiences of the LOD2 project in applying linked open data to public procurement. The LOD2 project developed tools like Strigil and ODCleanStore to extract, clean, and link procurement data. A mockup public contracts filing application was created to publish and matchmake procurement data. Visualizations were also created, like a heat map of Czech public spending and a network graph of German procurement flows. Challenges included unclear licensing, improving machine readability and entity reconciliation across countries. Next steps could involve working with the European Commission's Open Data Portal to further develop the vision of a distributed marketplace for public contracts.
