OpenSAFELY Contracts reference🔗

Danger

This page discusses the new OpenSAFELY Data Builder for accessing OpenSAFELY data sources.

Use OpenSAFELY cohort-extractor, unless you are specifically involved in the development or testing of Data Builder.

OpenSAFELY Data Builder and its documentation are still undergoing extensive development. We will announce when Data Builder is ready for general use on the Platform News page.

This page will be a reference for OpenSAFELY Contracts.

It is likely that much or all of this content will be automatically generated from the Data Builder contracts code.
