  1. Conclusions Retention is a business issue not an afterthought Immortal Information

  2. Long Term Data Retention Sean Barker BAE SYSTEMS, Advanced Technology Centre sean.barker@BAESYSTEMS.com With thanks to LOTAR, AIA & PDES Immortal Information

  3. Contents • From Drawings to Models • Changes in IT Environment • Scope of the problem • Approches • OAIS • LOTAR • Immortal Information Immortal Information

  4. Part shape is modelled to produce drawings more easily Computer as Electronic pencil Automated redrawing after small changes Geometry Modelling Product Modelling Part model includes shape, materials, tolerances A Brief History of CAD Manual Drawing Immortal Information

  5. Manual Drawing Drawing is the master Computer as Electronic pencil Geometry Modelling Product Modelling Model as master What is the master? Immortal Information

  6. Contents • From Drawings to Models • Changes in IT Environment • Scope of the problem • Approches • OAIS • LOTAR • Immortal Information Immortal Information

  7. Life of Operating System: 18 months Life of Computer: 3 years Time between CAD Versions: 6 months Life of CAD System: 10 years Life of Product: 70 years + Rates of Change time Immortal Information

  8. An Example of Generation Change Immortal Information

  9. Implications When we update a model in 20 years time: • CAD System replaced twice • The hardware replaced 6 times Given old software on an old computer, we need person who remembers how to use it. Chances of reading old CAD data? Immortal Information

  10. Contents • From Drawings to Models • Changes in IT Environment • Scope of the problem • Approches • OAIS • LOTAR • Immortal Information Immortal Information

  11. Retention or Archiving? Immortal Information

  12. Scope of the Problem • Keep Hardware out of scope • Keep Data OAIS Repository • Keep Information LOTAR • Keep Knowledge Immortal Information Immortal Information

  13. Contents • From Drawings to Models • Changes in IT Environment • Scope of the problem • Approches • OAIS • LOTAR • Immortal Information Immortal Information

  14. OAIS Overview Immortal Information

  15. OAIS • Standard to compare Archive systems • Covers Producer to Consumer • Defines • terms • processes • NOT data formats • Ingest agreement Immortal Information

  16. LOTAR Developing European Aerospace Standard • Detailed guidance for • CAD • PDM • etc (but later) • Data Validation • Information Authentification Harmonize with AIA (US Aerospace) Immortal Information

  17. Money down drain Manual, high cost Design Approval Decision Use Now Automatic, low cost, can be part of QA Fit to Archive Archive Archiving as Afterthought Design Use now Fit to Archive Approval Decision Archive Retention Integral to Design Key Issue - Retention is not an Afterthought Immortal Information

LDTR Working Group Aerospace Industries Association Working Group Chair:Jean-Yves Delauney Chair:Gerald Graves Chair:Rick Zuray LOTAR, AIA, PDES and IAQG International Aerospace Quality GroupLong Term Archival & Retrieval Project Immortal Information Detailed working group structure

  19. Immortal Information What should we archive? • What is the basic information? • What is the configuration information? • What is the context information? • What is the validity information? What about the Rationale? Immortal Information

  21. Conclusions • Long term retention is a complex problem • OAIS covers the general concept of archiving • AIA & LOTAR specialise OAIS for Aerospace • LOTAR adds details for CAD, PDM, etc • Immortal Inforamtion will look at what should be retained Retention is a business issue not an afterthought Immortal Information
