During 22 - 25 November I joined the 14th RDA Plenary in Helsinki with the great pleasure of being selected as one of the RDA EU domain researchers and data Experts. It was my first experience with the RDA plenary: large scale, broad scope, inspiring and professional working conference. I would like to share a few humble thoughts on interdisciplinary research based on some dedicated discussions during the week. Writing them up continued the learning process on how to provide RDM support for this type of research.
