PREMIS and DAITSS

DAITSS is strictly modeled on OAIS with PREMIS support for format normalization and migration. It ensures data integrity through events recording and ingestion workflows. Get more information from the Florida Digital Archive or contact pcaplan@ufl.edu.

Presentation Transcript

  1. PREMIS and DAITSS

  2. DAITSS • Strictly modeled on OAIS • “Dark” – no online public interface • Implements format normalization and forward migration at time of Ingest • DAITSS 1.0 partly PREMIS conformant • DAITSS 2.0 entirely conformant

  3. PREMIS Support In DAITSS 1 • Intellectual Entities and File Objects • Bitstream objects but non-conformant • AIP & DIP Descriptors = METS + local DAITSS schema • Could supply most PREMIS values by mapping from DAITSS stored values • No Environment or Significant Properties

  4. PREMIS Support In DAITSS 2 • AIP & DIP Descriptors = PREMIS-in-METS • validated with Schematron • Implement Representation Objects • if any SIP file(s) normalized or migrated, new representation created • Make BitStream Objects conformant • follow definition in the data dictionary

  5. Events in DAITSS 2 • Crucial to Ingest workflow • relies on Events to know what’s been done • Can Ingest external Events • e.g. from TIPR Exchange Package • Events occuring after Ingest (i.e. fixity checks) • recorded and saved • added to Descriptor at time of Dissemination
