21. DAITSS: Dark Archive in the Sunshine State DCC Workshop on Long-Term Curation, July 2005  Creating multiple master copies of files  Calculating two message digests  Storing metadata as XML and in RDBMs  Normalizing files when possible  Always retaining original packages as submitted

22. DAITSS: Dark Archive in the Sunshine State DCC Workshop on Long-Term Curation, July 2005 Next steps for DAITSS  Finish programming Dissemination Forward migration  Go into full production in the FCLA Digital Archive  Implement at a few partner institutions  Release as Open Source Software  Continue adding support for more formats  Make fully PREMIS-compliant

23. DAITSS: Dark Archive in the Sunshine State DCC Workshop on Long-Term Curation, July 2005 Next steps for the FCLA Digital Archive  Implement DAITSS in full production Retrospective Prospective  Investigate repository certification  Test exchange of packages with other repositories  Collect cost data and model cost recovery
