Why?
Losing the Moment
• What we share != What we curate
• 4.2% of Twitter is perfectly archived
–Losing My Revolution: 11% gone in 2 years
• 34.2% of Archive-it is perfectly archived
• Accessibility? Gov vs. non-Gov?
Measuring memento damage
VS.
Not all embedded resources are
created equal
Not all embedded resources are
created equal
Planned Work
• Evaluate importance of missing stuff
–Size, position
–# CSS Classes
–Not all stylesheets created equal
– Missing border vs missing functionality
– “Whitespace”
–Provide Web service
• Mechanical Turk evaluation of “damage”
• Evaluate collections of mementos
What does it all mean?
• Archivability is measurable
• Damage is measurable
• If we can predict archivability….
–We can try new methods of archiving on “hard to
capture” mementos
–Attempt repairs on existing mementos
–Gauge our successes in real-time
• Next step: capturing dynamic content
