When it comes to configuring DataTrails itself the DataTrails platform recognizes only 2 roles: Regular Users, and Root Users (who are able to do everything the Regular User can do, plus configure tenancies and access certain restricted management functions).
However when it comes to accessing Asset and Event data stored in the platform it is extremely flexible thanks to the use of Attribute-Based Access Control in Access Policies and Bring-Your-Own-Identity login.
