  31. 31. A practical use caseTuesday, July 21, 2009
  32. 32. The Library of Congress Digital Preservation • 180+ Partners • Located across the globe • Groups have different charters, goals, budgets • Many of these groups would benefit from sharing and connecting their data • But it exists in many disconnected silos...Tuesday, July 21, 2009
  33. 33. What’s the Answer? • Empower users to create their own views of data to satisfy different job roles and changing needs • Build a community around the data in which users help each other to curate and connect as needed • Skip the supermodel - Leave data in the multiple “best of breed” systems; wrap and expose using the Web as a platformTuesday, July 21, 2009
