Thorny,

If you switch to using a managed content datastream, how do you maintain an 
audit trail? (This is already a problem we are confronting with our 
non-metadata managed datastreams, but the majority of our modifications are to 
the metadata.)

I see how you can force an audit trail via Fedora: edit the external content 
datastream, and then run a modify into Fedora doesn't change anything but at 
least update the audit trail saying "a change happens". But there's no way, 
then, for Fedora to know what the change was and maintain a log of it. Do you 
recommend managing all of the external datastreams in some other revision 
control system, such as RCS or Subversion?
