Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for access control for enterprise information. In one aspect, a method includes receiving resources of an enterprise, each resource having a respective access control list specifying access privileges to the resource for one or more members, and the resources including entities related to the enterprise and relationships; identifying entity facts of the entities from the resources; determining, for each entity fact, an entity fact access control list; storing data describing the entities, entity facts and the respective entity fact access control lists, wherein each entity fact is associated with its corresponding entity fact access control list; and providing, to each of the members of the enterprise, access privileges to the data describing the entities and the entity facts according to the respective entity fact access control lists.
