  1. An Introduction to Tessella and The Safety Deposit Box Platform Mark Evans Digital Archiving Practice Manager

  2. Tessella Overview • What we do • Information technology & consulting services for leaders in R&D, science, engineering and archiving • Archiving is one of our two major technology focus areas • Flexible & end to end support • Key facts • Established in 1980 • ~200 S/W Engineers and Consultants • 60% of staff hold PhDs • What makes us different • Archiving and Preservation experts • 10 years of practical experience • Delivered real preservation solutions • Well qualified S/W engineers & consultants • Effective partnering at all levels • Part of a consortia • Large systems integrators • Acting as a prime • Research colaboratives

  3. Tessella Locations • Dedicated archive practices in • Abingdon UK • Washington DC

  4. Consultancy Long Term Support Research Complete Archiving Solution SDB Technology: Archive & Active Preservation Customization & Integration Archiving Services

  5. Genuine Innovation in Archiving Developed online file format registry with UK National Archives, used to dictate preservation strategies. Open source file identification tool using digital “fingerprint” to identify file formats, developed with UK National Archives. SDB – Safety Deposit Box Digital Archive platform that provides “Active Preservation” Capabilities Open source x86 emulator build for KB (Royal Dutch Library) and Nationaal Archief (Dutch Archive).

  6. Digital Preservation Research 150 man year EU funded research into preservation strategies with 15 leading organisations. Keeping Emulation Environments Portable: - EU funded research for the development of an Emulation Access Platform DataNet program – Development of a national infrastructure to suport the long term preservation and access of scientific data

  7. Example Digital Archiving Projects • National / Regional implementations • 8 instances of SDB • NARA ERA program • Subcontractor to Lockheed Martin • Life sciences • Archiving of digitally signed Electronic Lab Notebooks (ELN) • Global Digital Archive • Consultancy • Needs assessment for UK houses of Parliament • Education seminar to agencies in Canada

  8. OAIS Preservation Planning Data Management Ingest Access Archival Storage Administration Safety Deposit Box Based on the OAIS reference model Evolving technology since 2003 In use at leading institutions Includes “Active Preservation” framework (safeguard against technology obsolescence)

  9. Safety Deposit Box

  10. UK National Archives Dutch National Archives Safety Deposit Box – Deployed Locations The British Library Rotterdam Regional Archives • Wellcome • Trust Library Swiss Federal Archives Malaysian Archives

  11. Safety Deposit Box - Offerings • SDB can be offered in 3 primary configurations Standalone Archive Accession builder SDB search & browse Accession auto-loader Web service API Custom workflows Black-box Archive Custom / 3rd party access 3rd party applications Active Preservation Plug-in Storage adapter 3rd party content storage

  12. Ingest toolkit • Create an SDB SIP from received content • Receive SIP (files + metadata) by: • File copying • ftp • SOAP • Perform SIP Checks: • Consistency checks • Fixity check • Virus check • Characterization • Ingest Delete requests • Ingest Edit requests

  13. Passive Preservation Metadata Store • Represents the AIP (SDB supports a logical AIP approach) • Based of the Planets core data model • Structure of records • Association of files to records • Technical metadata • Descriptive metadata • Full audit trail • Significant properties • Configurable metadata schema • Any registered schema , e.g. MARC, PREMIS etc • Automated integrity checking

  14. Active Preservation Three main components • Characterization • What do I have in my archive? • Preservation planning • What am I going to do to guard against obselescence? • Preservation Processing (Migration) • Select an approved pathway • Execute • Validate • Re-ingest and associate to the original

  15. Active Preservation • Technical registry is the cornerstone of the active preservation framework • Contains Factual information • Formats • Software • Hardware • Tools • Contains Policy Information: • Risks / obsolescence • Significant properties • Tool usage • Migration pathways

  16. Characterization • Characterize files: - Use a framework approach • Basic: file size, last modified date • Format Identification (DROID) • Format Validation (JHove) • Property extraction (Jhove plus others) • Embedded object extraction: • Iterative characterisation • Record Components: • Discover • Measure invariant properties of the components

  17. Preservation Planning SDB uses a risk based approach • Determine risk of formats • With properties (e.g. LOC sustainability factors) • Determine files at risk • Determine records at risk: • Build list of things to migrate • Look up best migration pathway: • Allow manual approval

  18. Preservation Action - Migration • Perform approved pathway • Complex mappings allowed • Partial migrations allowed • Validation: • Re-measure invariant properties • Tool specific • Ingest migrated files + metadata
