Private data: only available to project owners.
Controlled data: (also called controlled access data) available to registered users that fulfill specific requirements for data access, such as submitting an Intended Data Use statement, obtaining IRB approval, or other prerequisites.
Open data: (also called open access data) available for all registered Synapse users.
