Presented as a keynote talk by Shelley Stall at the #SciData19 Better Science through Better Data 2019 Meeting in London, UK hosted by Springer Nature, Scientific Data, and the Wellcome Trust. Techniques for ensuring your work as a researcher can be easily discovered, understood, and able to be reused with credit to you and your co-authors. Three slides are directly from a presentation given by Martin Fenner at the PARSEC meeting co-located with RDA P14 about the FREYA project and the PID Graph.
