Digitization of Physical Assets Digitization of Physical Assets Presentation Transcript

  • Digitizing Legacy Documents
  • What Is Legacy?
  • Files in the Library
  • Paper
  • Microfiche
  • PDF
  • What’s Next?
  • Reel-to-Reel
  • Cassettes
  • CDs
  • iPods
  • What’s Next?
  • Celluloid
  • Video Tapes
  • DVD
  • What’s Next?
  • Magnetic Tape
  • 5 ¼ Floppies
  • Hard Drives
  • 3 ¼ Floppies
  • Flash Drives
  • The Internet
  • What’s Next?
  • The Scenario
  • What We Know
    • The client wants to go online with their courses.
    • The courses are composed of ppts, images, videos, documents, and audio (for our purposes: legacy materials). 
  • What We Don’t Know
    • These courses may also use older materials, such as video tapes, floppies, microfiche, and photocopies.
    • These materials may already be virtual, but we can assume from the nature of the question that a portion are physical. We don't really know.
    • They may be synchronous or asynchronous courses and materials, but we don't know.
  • The Approach
    • The groups doing the most work on conversion from legacy materials to digital materials and their deployment are museums, libraries and universities, and public sector organizations.
    • These organizations have already stumbled on benchmarks and constraints (i.e. the size of video files, cost of conversion, cost of storage, etc.) and navigated around problems.
    • The move from physical training materials to digital materials is analogous to moving classes online.
  • Analyzing Needs
    • How do you decide what to digitize and what not to?
  • It Depends…
    • Depends on your mission and your organization
    • Depends on the media
    • Depends on your users
    • Begin with the End in Mind
  • Principles to consider
    • Cost
    • Use
    • Condition of original
    • Rescanning in future?
    • Type of organization
    • Begin with the End in Mind
    • Customize and Tailor
  • Different Materials Different Problems
    • Paper documents are the least complex due to standardized nature and use of content
    • Audio is complex due to changing formats. Reformatting may occur less often than video but more often than text
    • Video and film are the most complex due to both visual and audio elements, reformatting may be needed often
  • Cost of Digitization
    • Technology is becoming less expensive
    • Cost of storing digital materials
    • Cost of storing analog materials
    • Labor (human hours)
  • Digitizing for Employee Performance
    • Broader access to materials allows employees to perform job tasks more efficiently
    • Centralized repository allows access from any location
    • Allows employee access regardless of frequency of content use
    • Ensures accuracy of performance due to access to documentation
  • Four Ways to Digitize
    • To optimize resource allocation, digitize to fit your client’s needs:
          • Preservation
          • Use
          • Access
          • Commerce
  • Digitization for Preservation
        • Use lossless formats (such as JPG 2000, MPEG 2 “I” frame only)
        • Standardized formats across industries
        • Files tend to be very large and expensive to store and transport
        • Highest Cost in human hours
        • Video sizes: 30-90 GB per hour
        • Highest technology requirements for recipients
  • Digitization for Use
        • High quality, but efficiently compressed
        • Examples include standard MPEG 2 (DVD format) video, and possibly Quicktime and WMV at higher quality
        • Files are large, but not as large as preservation files
        • Possible to transfer over internet or LAN
        • Video file sizes: 2-8 GB per hour
  • Digitization for Access
        • Small file size, but typically lower resolution
        • Able to be streamed over internet or LAN
        • Cross-platform formats, including WMV, QT and RM
        • Video file sizes: 150-400 MB per hour
  • Digitization for Commerce
        • Very small file sizes, but low quality
        • Used as advertising on websites, digital book previews (i.e. Amazon.com), or small scale music samples
        • Cross-platform, lossy, formats including Flash, PDF, and mp3.
        • Video file sizes: 20-80 MB per hour
  • To Consider
    • Cost
    • Use
    • Condition of original
    • Migrating in future?
    • Type of organization
    • Begin with the End in Mind
    • Customize and Tailor
  • Scenario 1
  • Scenario 2
  • Scenario 3
  • Scenario 4
