Ideally telecommunications policy decisions would be based on easily understandable data collected by several, federated, independent, open-source network measurement tools based on documented methodologies. In reality, most measurement tools are fragmented to such an extent that their data are limited in comparability and not immediately accessible to inform policy. This paper tries to understand how we could improve the current situation. We describe how successful internet measurement tools managed to foster their adoption by users. We argue that cooperation is the key to reduce the burden on individual project maintainers and we model factors reducing incentives to cooperate. We set forth an agenda for increasing cooperation and we provide examples of cooperation between projects.
