1 Dr. Dinesh Katre Chief Investigator Centre of Excellence for Digital Preservation Associate Director & HOD Human-Centred Design & Computing Group C-DAC, Pune, INDIA. Digital Preservation Requirements of Electronic Educational Content (A Perspective of National Digital Preservation Programme)

2 Punch cards Punch tapes Selectron tubes Magnetic tapes Audio Cassette Magnetic Drum Evolution and obsolescence of storage media

3 8-inch floppy disk 5 ¼ floppy disk 3 1/2 inch floppy disk Compact disk Hard disk DVD Evolution and obsolescence of storage media

4 Discontinued Tools, Closed Formats and Outdated Storage Devices Computer hardware Continued changes in CPU speed, memory, processing, etc. New hardware introducing new peripheral connections Operating System Upgraded versions or new OS does not run the old software Continued transition from 8bit OS to 64bit OSs and so on Software Software upgrades do not support the former file formats Proprietary and closed source software Discontinuation of software, lack of support File formats Proprietary and closed format specification Change in the format specification Discontinuation of the required software Data corruption Storage devices and media Continued reduction in size and cost of storage devices Continued increase in storage capacity and performance Polycarbonate media like CD and DVD have uncertain lifetimes (Cerf, 2010) Obsolete storage media and unavailable reading devices e.g. 5 1/4” or 3 1/2” floppies New approaches like storage virtualization Physical threats Improper storage environment (temperature, humidity, dust, light) Overuse and handling of media Natural disaster Infrastructure failure Human error Sabotage

5 Tangible versus non-tangible Electronic These & Dissertation

6 Definition Long Term Digital Preservation (LTDP) is a secure and trustworthy mechanism to ingest, process, store, manage, protect, find, access, and interpret digital information such that the same information can be used at some arbitrary point in the future in spite of obsolescence of everything: hardware, software, processes, format, people, etc. What does “Long Term” mean? How can we increase the likelihood that data generated in 2010 or earlier will still be accessible in useful form in 2020 and later? (Cerf, 2010) Data should normally be preserved and accessible for not less than 10 years for any projects, and for projects of clinical or major social, environmental or heritage importance, the data should be retained for up to 20 years“ (Research Councils UK 2008:6) An archive is expected to provide permanent or indefinite Long Term, preservation of digital information. (OAIS, 2009) Benefits Digital preservation provides benefits such as legal protection, knowledge heritage for future work / future generations, trend analysis, reuse etc. What is Digital Preservation?

7 1 Terabyte = 1,000,000,000,000 bytes B = Petabyte = 1,000,000,000,000,000 bytes B = Exabyte = 1,000,000,000,000,000,000 bytes B = Zettabyte = 1,000,000,000,000,000,000,000 bytes B = Digital Universe / Digital Dark Age As per the “Digital Universe Study Report” by International Data Corporation (IDC), Estimated Size of Digital Universe in million Petabytes or 1.2 Zettabytes Estimated Size of Digital Universe in Zettabytes (As all major forms of media –voice, TV, radio, print would have completed the journey from analog to digital.) Estimated Size of Unprotected Data needing protection in ,000 Exabytes

8 Sustainable Economics for a Digital Planet, Ensuring Long Term Access to Digital Information, February 2010 – A report prepared by Blue Ribbon Task Force What digital information should we preserve? Who will preserve it? Who will pay for it?

15 National Study Report on Digital Preservation Requirements of India Volume – I Recommendations for National Digital Preservation Programme Chapter 1. Need of Digital Preservation Chapter 2. Scope of Digital Preservation in India Chapter 3. Recommendations for NDPP Volume – II Position Papers by National Expert Group Members 23 Status Reports Stakeholder Recommendations Short Term (3Yrs) and Long Term Actions (10Yrs)

16 A) Conduct research and development in digital preservation to produce the required tools, technologies, guidelines and best practices. B) Develop the pilot digital preservation repositories and provide help in nurturing the network of Trustworthy Digital Repositories (National Digital Preservation Infrastructure) as a long-term goal. C) Define the digital preservation standards by involving the experts from stakeholder organizations, consolidate and disseminate the digital preservation best practices generated through various projects under National Digital Preservation Programme, being the nodal point for pan-India digital preservation initiatives. D) Provide inputs to Department of Information Technology in the formation of national digital preservation policy and strategy by identifying and selecting the activities for the National Digital Preservation Programme. E) Spread awareness about the potential threats and risks due to digital obsolescence and the digital preservation best practices.
