Presentation given at 2nd DPHEP Collaboration Workshop at CERN on 12 March 2017. The talk reflects on machine-actionable DMP use cases developed during an IDCC workshop (http://www.dcc.ac.uk/events/workshops/postcard-future-tools-and-services-perfect-dmp-world) and activities underway or planned by the DCC and UC3 teams. These will be implemented in the DMPRoadmap codebase to pilot in our respective tools, DMPonline and DMPTool
