A parallel output of the P2Pvalue project is the extensive directory of CBPP cases, at the European level and, more recently, another dedicated directory of the Catalan CBPP “ecosystem”. Both directories support an open and collaborative effort to map the many different examples of CBPP. The international directory currently features more than 300 cases of CBPP, while the Catalan one more than 1.000 projects. All data is freely available in open formats, and also resulting in different visualizations. We encourage other researchers, experts and representatives of communities of practise to participate in the co-creation of a rich resource for research in this emerging field.
