The Birds of a Feather sessions were a new feature of the IDCC conferences introduced in 2015. I attended the session on 'Building Infrastructure for scientific data: Contrasting curation approaches across the lifecycle" in which practitioners compared notes on the tools they are providing for researchers to curate their data. The aim of the session was explained by the conveners as "to bring people together to talk about succeses in building infrastructure and effectively engaging scientists in data curation and overcoming challenges".
