As of version 3.3 it is not yet It is currently not possible to directly retireve retieve the audit datastream. Therefore, in order to see the audit datastream, you'll need to export the xml of the object. For example: http://localhost:8080/fedora/objects/changeme:1/objectXML
. It will appear in the export as a datastream called "AUDIT".
In the future, we hope this will be simpler. See https://fedora-commons.org/jira/browse/ FCREPO-635
