Audit and outsourcing: their role in creating interoperable repository infrastructure

  1. 1. Audit, outsourcing and interoperability of preservation Kevin Ashley, ULCC [email_address]
  2. 7. repositories preservation infrastructure interoperability
  3. 9. Interoperability - a wider view <ul><li>Interoperability isn’t just metadata, APIs and wire protocols </li></ul><ul><li>It’s policies, comparability and markets </li></ul><ul><li>People want to compare services </li></ul><ul><li>We need trust in transferability </li></ul>
  4. 10. An external perspective <ul><li>None of us are perfect </li></ul><ul><li>Without oversight, standards can slip </li></ul><ul><li>External perspectives encourage improvement </li></ul><ul><li>Audit formalises this </li></ul>
  5. 12. Repository Audit Mechanisms <ul><li>TRAC </li></ul><ul><li>DRAMBORA </li></ul><ul><li>NESTOR </li></ul><ul><li>DINI </li></ul>OAIS: http://wiki.digitalrepositoryauditandcertification.org
  6. 13. But what about interoperability? <ul><li>Easier to please auditors when using standards </li></ul><ul><li>Easier to compare A with B </li></ul><ul><li>Audits themselves - in standard form - allow consumers, depositors to compare </li></ul><ul><li>Is A better value/more trustworthy/more secure/more open than B? </li></ul>
  7. 14. An trivial example <ul><li>What is the likelihood that you will lose 1 bit in X years ? </li></ul><ul><li>What confidence limits apply to that number ? </li></ul>
  8. 15. Not so trivial <ul><li>What is the energy cost of preserving X bits over Y years ? </li></ul><ul><li>Do you do an environmental audit ? </li></ul><ul><li>Are you certified against recognised standards ? </li></ul>
  9. 16. Interoperable policies <ul><li>I give you content - we have an agreement </li></ul><ul><li>Content is later transferred - merger, takeover, change of collection policy </li></ul><ul><li>Is my agreement transferred ? </li></ul><ul><li>Who do I sue ? </li></ul>

  11. 18. Outsourcing
  12. 20. How does it help <ul><li>Contracts, service level agreements, performance measures </li></ul><ul><li>Comparability is desirable </li></ul><ul><li>Interoperability - of a form - follows </li></ul><ul><li>Customers don’t like lock-in </li></ul><ul><li>Intelligent ones design it out - exit plans </li></ul>
