DAITSS: Dark Archive in the Sunshine State DCC Workshop on Long-Term Curation, July 2005 Format migration and normalization

DAITSS: Dark Archive in the Sunshine State DCC Workshop on Long-Term Curation, July 2005 Format treatment  Treatment based on background reports and action plans  Recognized formats can get full preservation treatment  Files are normalized on Ingest if possible  Files are migrated on Ingest if necessary  Files can be migrated by Disseminating and re- Ingesting  AIFF 1.3  AIFF-C 1.0  JFIF 1.02  PDF 1.2 – 1.6  Plain text  TIFF 5.0, 6.0  WAVE  XML 1.0  XML DTD 1.0 In process  JPEG2000  AVI MPEG, pcm

DAITSS: Dark Archive in the Sunshine State DCC Workshop on Long-Term Curation, July 2005 Redundant redundancy

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

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

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
