Roles Permissions Matrix

Doccano relies on Django REST framework permissions (permissions.py) and also extend them permissions.py to perform user authorization. This is explained in a later section titled Authorization in Doccano

The following table represents the proposed association b/w roles and permissions in Doccano. Currently, roles are not implemented so following permissions are not used during authorization of a user.

Permissions(P) are represented by the rows and Roles(R) by the columns.

*Not currently available but can be added.

Permission	Condition
IsProjectUser	User has access to the project.
