18 Format migration and normalization
DCC Workshop on Long-Term Curation, July 2005

19 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 DCC Workshop on Long-Term Curation, July 2005

20 DCC Workshop on Long-Term Curation, July 2005
Redundant redundancy DCC Workshop on Long-Term Curation, July 2005

21 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 DCC Workshop on Long-Term Curation, July 2005

22 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 DCC Workshop on Long-Term Curation, July 2005

23 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 DCC Workshop on Long-Term Curation, July 2005
