This authorization delegate makes decisions based on the four basic roles of "metadata reader", "reader", "writer", and "admin". These roles are assigned to principals on Fedora objects and datastreams. Assigned roles are inherited through the repository tree until blocked by another assignment.
The role metadata reader has not yet been implemented.
This authorization delegate makes use of the Access Roles Module to assign and query roles in the repository.
Roles
- metadata reader - can retrieve information about Fedora objects, but cannot retrieve content
- reader - can retrieve information about Fedora objects, including content
- writer - all permissions of reader; can create, modify and delete Fedora objects
- admin - all permissions of writer; can modify the roles assigned to Fedora objects
Policy
The permissions granted to these roles are fixed. This authorization delegate makes decisions in Java code, rather than consulting any kind of declarative policy.
Role/Permission Matrix
metadata reader | reader | writer | admin | |
---|---|---|---|---|
read properties | X | X | X | X |
read content | X | X | X | |
write | X | X | ||

Configuring the Basic Role-Based Authorization Delegate
See Authorization Delegates for more information on how an authorization delegate is configured.
Edit your repo.xml file to configure the authentication provider. The file should contain these three beans, as shown:
<bean name="modeshapeRepofactory" class="org.fcrepo.kernel.spring.ModeShapeRepositoryFactoryBean" <bean name="fad" class="org.fcrepo.auth.roles.basic.BasicRolesAuthorizationDelegate"/> <bean name="authenticationProvider" class="org.fcrepo.auth.common.ServletContainerAuthenticationProvider"> <property name="fad" ref="fad"/> |

Edit your repository.json file to enable an authenticated internal session between Fedora and ModeShape, such that the security section matches the example shown:
"security" : { |
