There is certainly a great deal of interest in audit and certification.
The demand for something started more than 15 years ago. It was re-iterated in OAIS.
Now EU are promoting a European frameowrk for Audit and Certification of digital repositories – see http://wiki.digitalrepositoryauditandcertification.org/bin/view/Main/EuropeanFrameworkDocs
The ighest level of this is the ISO audit and certification standard which I believe will completely change the market in digital preservation.
