The Third Plenary of the Research Data Alliance has the title ‘The Data Sharing Community: Playing YOUR Part’. It is concerned with exploiting the potential of RDA’s work to date; addressing all parts of the data lifecycle. The programme contains a mixture of keynotes, panels, networking, Working and Interest Groups, as well as ‘Birds of a Feather’ sessions on a variety of topics from numerous domains. In particular, the joint RDA–WDS Interest Groups on Publish Data and Certification, as well as the Working Groups beneath their umbrellas, will hold breakout sessions during the Plenary.
