  2. The digital preservation problem • Information is being produced in greater quantities and with greater frequency than at any time in history. • How will society preserve this information and make it available to future generations? • How will libraries and other repositories classify this information so that their patrons can find it with the same ease that they can locate a book on a shelf? • The ease with which electronic information can be created and "published" makes much of what is available today, gone tomorrow. Thus there is an urgent need to preserve this information before it is forever lost. [Library of Congress (http://www.digitalpreservation.gov)]

  3. About NDIIPP • The National Digital Information Infrastructure Preservation Project is a $99.8M national digital strategy effort led by the Library of Congress. • Its mission: Develop a national strategy to collect, archive and preserve the burgeoning amounts of digital content, especially materials that are created only in digital formats, for current and future generations. http://www.digitalpreservation.gov

  4. Library of Congress NDIIPP Program Building Digital Preservation Infrastructure • Partnerships • Policy • Standards • Technical components

  5. NDIIPP key areas of interest Digital Preservation … • Practical applications and models • National technical architecture • Basic research

  6. ECHO DEPository – Overview • Design selection methodology • Develop software implementing theory • Machine-assisted • Open source • Evaluate various repositories • Using content gathered from tools • Other content providers • Study semantic preservation techniques

  7. Three objectives • Comparative test of repositories with various digital collections • Development of Web Archives Workbench • Investigations of semantic digital preservation and alternate applications of workbench tools

  8. Project Partners • University of Illinois, Urbana-Champaign • Libraries, GSLIS, NCSA, WILL, DMI • OCLC • State Libraries of Arizona, Connecticut, Illinois, North Carolina and Wisconsin • Tufts – Perseus Project • Michigan State – Sounds Archives • Library of Congress, NDIIPP Program • $3 million funding over 3 years

  11. The Arizona Model • Web domains as “archival collections” • Creates efficiencies for … • Selection of “documents” • Name authority & other metadata • Browseable access

  12. Arizona Model: a new approach • Assumptions • Content creators won’t help • Item by item selection is unsatisfactory • Bulk harvesting is unsatisfactory • An archival approach • Identifying groups of similar material (series) • Automatic identification of new series items • Series description • Item level description is possible if warranted • Ingest of documents into an archive

  13. Web Archives Workbench (WAW) Tools for curators … • Discovery– identify & manage domains • Properties– associate metadata, content, and providers • Analysis– select content from structure • Packager– package content & metadata
