Big Data to Knowledge (BD2K) is a project of the National Institutes of Health for knowledge extraction from big data. BD2K was founded in 2013 in response to a report from the Working Group on Data and Informatics for the Advisory Committee to the Director of the National Institutes of Health. A significant part of BD2K's plans is to have organizations make plans to share their research data when they make a proposal in response to a funding opportunity announcement. Philip Bourne is the lead in managing the project.
