About access rights
You can determine which DITA CMS features to which users can gain access by defining access rights.
Access rights control the point at which various users are active in the document cycle, the type of documents they can manage, and the operations that they can carry out. Roles allow you to manage user access rights.
Note: Companies with a complex user hierarchy might use groups as well as roles to assign access rights. For example, some organizations might create a “Senior Writers” group and another named “Summer Students”, each with different levels of access.
