Format migration and normalization

DCC Workshop on Long-Term Curation, July 2005

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

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
