Cohorts refer to groups of individuals who share specific characteristics relevant to one or more research questions. Enabling the search for cohorts across diverse data repositories allows researchers to aggregate more data for their studies. Currently, a gap exists in our ability to formulate queries that readily retrieve federated results from multiple data repositories. The GA4GH Federated Cohort Building study group aims to explore existing GA4GH tools and standards to address this challenge and assess the need for additional components.
