The importance of moving towards a public procurement data space will be discussed, taking into account various perspectives. The panellists will try to answer several key questions relating to the data space, such as: how can it help to better understand EU and national public procurement systems and rules? How can it help to improve data quality? What role will the upcoming eForms and eProcurement Ontology play? Why is open data important for making public procurement more transparent to citizens, NGOs and the academic sector? And finally, how will it help to reach out to more SMEs?
