In this BoF [Birds of a Feather Discussion Session] we seek engagement with researchers and eResearch professionals to explore different approaches to having conversations about research data access and reuse. Rather than typifying open data as an all-or-nothing dichotomy, the discussion will be framed around the idea of a continuum of openness. Key areas to be explored include research communities expectations of reciprocity, and the changing expectations of funding agencies and publishers. Another topic for discussion is the current and future roles for libraries, data librarians and eResearch intermediaries in research data management. One of the biggest hurdles in beginning the eResearch discussion with researchers is explaining about this spectrum of open data and quelling fears that all data will have to be completely open. This discussion will look at the complexities involved with supporting researchers and informing them about all the different levels of openness. This BoF will also look at education and training as it relates to open data and building capabilities among both support professionals and researchers.
