CMIS: Mapping of ACLS to allowable actions

Repository maps the basic cmis permissions to allowable actions. You can see how these mappings are done using cmis work bench.

Get the mappings using cmis workbench

Open cmis workbench. Click on the button ‘Repository Info’

Go to Permission Mapping section, you can able to see how these allowable actions are mapped to basic cmis permissions.

Get the mappings programmatically

You can also get these mappings programmatically by querying repository capabilities.

                  Map<String, PermissionMapping> permissionMappings = session.getRepositoryInfo().getAclCapabilities()

                                    .getPermissionMapping();

                  for (String key : permissionMappings.keySet()) {

                           PermissionMapping permMapping = permissionMappings.get(key);

                           System.out.println(key + " : " + permMapping.getPermissions());

                  }

Find the below working application.
