  1. Long-Term Knowledge Retention Joshua Lubell Manufacturing Systems Integration Division, NIST FIRM’s Forum at FOSE March 20, 2007

  2. The problem • Too much digital data! • It takes about 15 minutes for the world to churn out new digital information equivalent to the entire collection in US Library of Congress • Proprietary file formats • Expected lifetime of typical manufacturing software application only 3 years • Short-lived Computing hardware and software • Expected lifetime of today’s storage/retrieval technologies only 10 years • Products often outlive computer software/hardware by an order of magnitude • Aircraft can last 50 years or more • Healthcare records should be preserved through the patient’s lifetime, and perhaps beyond

  3. Data standards • Necessary to avoid being locked into a vendor format or application that could disappear in the near future • Likely to be more stable than proprietary tools/formats • But data standards are only part of the solution • Information is more than just data!

  6. Tools for tackling LTKR • Standards for representing digital artifacts • STEP – ISO 10303 (product data) • XML (documents) • Graphics, audio, video, multimedia standards • Scientific modeling standards • Standards for representing preservation information • Ontology languages • Packaging standards (METS, XFDU) • Digital format registries (UK Archives, Harvard, Univ. of Maryland)

  7. March 2006 LTKR workshop • Diverse group of 35 met at NIST • Industry, academia, government equally represented • Immediate goal: identify challenges, research, and implementation issues in digital preservation of information • Emphasis on design and manufacturing • Next step: develop roadmap identifying areas of investigation and experimental testbeds for archival of design and manufacturing information

  8. Observations • LTKR seen by many as a process • Apply archiving methodology (e.g. OAIS reference model) to collection of digital artifacts • “Repository-centric” • Alternative “document-centric” view • Preservation and authenticity paramount • Archival process and data representation secondary

  9. More observations • Barriers to archiving • Lack of understanding, institutional support • Each scenario has its own unique requirements • Lack of formal methods and standards • Need a way to measure the quality of an archiving process • Library of Congress digital format sustainability criteria a good starting point • Recommendations • Create tools, methods for capturing business and manufacturing process workflows • Collect and preserve case studies of archiving successes and failures • Develop metrology for digital archiving

  10. Upcoming workshop • Long Term Sustainment of Digital Information: Putting the Pieces Together • April 24-25, 2007 at NIST in Gaithersburg, Maryland • Part of Interoperability Week @ NIST • http://digitalpreservation.wikispaces.com/LTKR+2007+Call+for+participation • Questions we will attempt to answer • How can you predict the future effectiveness of a digital preservation solution? • What combination of technologies is optimal for achieving success at a reasonable cost? • Registration deadline: April 9

  11. The time is now • Industry is feeling the pain • From a major aerospace company Vice President: Lack of archiving support could derail our efforts to move from a drawing-centric to a model-centric business model • Federal regulators recently fined Morgan Stanley $15M for failing to produce emails sought in investigations • Government recognizes the need • “Maintenance of and access to long-lived science and engineering data collections and Federal records” a funding priority according to Networking and Information Technology Research and Development (NITRD) supplement to the President’s FY2007 budget • The technologies we need are becoming increasingly available
