Format migration and normalization

DAITSS: Dark Archive in the Sunshine State
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

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

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

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
