The All of Us Curated Data Repository (CDR) Data Dictionaries provide a detailed description of all metadata for the data tables that are used to populate the Registered Tier and Controlled Tier datasets. The tables described include standard Observational Medical Outcomes Partnership (OMOP) tables as well as the custom created tables used to support some of the program’s unique data types.
