Purpose: Platforms for computable biomedical knowledge are rapidly emerging to accelerate the application of biomedical knowledge into practice. At an inaugural Mobilizing Computable Biomedical Knowledge (MCBK) working meeting held in Ann Arbor, MI on October 18 & 19, 2017, the group took important early steps to: Engage critical dialogue on how to effectively develop and govern platforms for machine-executable biomedical knowledge to improve health and to build a pre-competitive computable biomedical knowledge community. This conference was significant for advancing work in areas that require computable knowledge to translate biomedical insights for better health: Learning Health Systems, Open Biomedical Science, and Clinical Decision Sup...
