Importance of Digital Archiving

• Analog Artifact Paradigm
  • Physical objects are
    • Stored, Left behind, Forgotten, then “rediscovered”
      • film negatives, video recordings, photographs, dcouments on paper, audio recordings on tape/discs,
        
      • These continued on attics, backrooms, not necessarily because they’re actively relevant, but not wanted to be thrown away
        
  • This Paradigm NO LONGER WORKS for assets today[[Screenshot 2023-11-05 at 4.13.03 PM.png]]
    • i.e. Facebook is one of the largest online photo repositories, this is based off of that
      
    • “Right now (2016) , more photos are taken every 2 minutes, than period of 1826 - 1900, when film was first getting off the ground…This poses an incredibly large challenge in archiving.”
      
    • After running out of storage on phone, computer, hard drive, cloud drive, have to decide, Do I want to expand, or delete content
      • This really denies us ability to rediscvoer old items, which are not put in old boxes in attics
        
      • How do we remind users to be mindful of what theyre deleting, and be mindful of how they’re considering the content they’re making?
        
• Preservation Technology
  • Sampling Rate :: # of times per second (kHZ) in which digital device samples or captures its environment
    • Commong sound sampling rates
      • 44.1 (CD), 48, 26, 192kHz
        
  • Bit Depth : # of data bits used per sample, higher bit depth, wider variety of volume in sound (soft vs loud) is captured
    • Common Bit Depth 16bit (CD), 24 bit (DVD, Blu-ray), 30/36/48 bit ( deep color)
      
  • Channels : # of individual audio streams in recording
    • Stereo = 2channel audio
      
• Categorizing with MetaData
