Overview

The Islandora XACML Editor provides a graphical user interface to edit XACML policies for objects in a repository or collection. It adds a new tab to each collection called Child Policy and a tab to each item called Item Policy, where permissions can be set on a per User or per Role basis for:

Dependencies

Drupal.org modules:

Installation

Install as usual, see this for further information.

Usage

Using the XACML Editor

Configuration

Fedora Configuration

It may be desirable--and in fact necessary for some modules--to disable/remove ene of the default XACML policies which denies any interactions with the POLICY datastream to users without the "administrator" role.

This policy is located here: $FEDORA_HOME/data/fedora-xacml-policies/repository-policies/default/deny-policy-management-if-not-administrator.xml

Solr Searching Hook

In order to comply with XACML restrictions placed on objects, a hook is used to filter results that do not conform to a searching user's roles and name. This hook will not function correctly if the Solr fields for ViewableByUser and ViewableByRole are not defined correctly as they are set in the XSLT. These values can be set through the admin page for the module.

Notes

The XACML editor hooks into ingesting through the interface. When a child is added through the interface, the parent's POLICY will be applied if one exists.

If XACML policies are written or edited by hand, it may result in unexpected behaviour.
