Open, accessible research data provides a foundation for scientific discovery. Despite clear data sharing benefits and increased data sharing expectations, hesitancy to share data is common in many scientific research domains. This case study highlights work underway in the National Institutes of Health (NIH)–sponsored project Helping to End Addiction Long-term® (HEAL) Data Ecosystem (HDE). HDE has initiated a suite of activities designed to engage HEAL-funded investigators and promote a data sharing culture. In this paper, we present results of a landscape analysis highlighting (1) common barriers to data sharing and (2) incentives identified by scholars that may help researchers overcome these barriers. We describe current strategies HDE employs to support a data sharing community.
