The DRAMA (Digital Repository Authorization Middleware Architecture) team has released version 1.2.1 of Muradora.
Here's an excerpt from the Muradora home page that describes Muradora:
Muradora is an easy to use repository application that supports federated identity (via Shibboleth authentication) and flexible authorization (using XACML). Muradora leverages the modularity, flexibility and scalability of the well-known Fedora repository.
Muradora's unique vision is one where Fedora forms the core back-end repository, while different front-end applications (such as portlets or standalone web interfaces) can all talk to the same instance of Fedora, and yet maintain a consistent approach to access control.
