  1. Digital Preservation in the United States Marine Band Evan Sonderegger SSgt, USMC evan.sonderegger@usmc.mil

  2. Who we are

  3. What’s in our archives

  4. Audio • 20,000+ files • 70+ days in duration • Growing at a rate of about 60 hours/year • Video • Only went HD in 2011 • Already twice as large as all our audio assets • Photos • Concert Programs, promotional materials

  5. How we got in to digital preservation • In 2000, concert recordings transitioned from DAT to CD-R • In 2007, we noticed many of those early CD-R recordings had unrecoverable errors • Digitization effort began with high-risk and high-value recordings • We didn’t know what we were doing. We just knew we needed to do something.

  6. How we store stuff • 4 NetgearReadyNAS RAID-5 arrays • Two primary, two backup, using rsync • MimsyXG running on Oracle 11g database • Reference web server • Ubuntu Server 10.04 • Running on PowerMac G5 • Connected to the world via cable modem

  7. Audio • Preservation • .wav files named by DB accession number • “best available” 16/24 bit, 44.1/96kHz • Access • .mp3 (LAME –v 2) • Generated automatically with id3 tags from master database by a series of scripts • Video • Preservation • ProRes 422 for HD content • .iso image file of DVD for SD Content • Access • 800 kbps h.264 with AAC audio stored in a mp4 wrapper

  8. What we’ve learned • Done is better than perfect. • A good access system makes justifying resources for digital preservation much easier. • Video is hard. • Mangled diacritics are a good warning sign that you’re doing something wrong. • We still have a lot to learn.

  9. Where we’d like to be doing better • Coordinating with other government institutions • Data integrity and provenance • Preservation of non audio-visual assets • Calendar information • Organizational email

  10. Thanks! (questions?)
