The ECHO DEPository was a 6-year (2004-2010) digital preservation research and development project at the University of Illinois at Urbana-Champaign, funded by the Library of Congress under their National Digital Information Infrastructure and Preservation Program (NDIIPP). 

Under NDIIPP, the ECHO DEPository had two phases:

Phase I (2004-2007)

Areas of ActivityPartners
  • Web archiving tool development
  • Repository evaluation
  • Interoperability tool development
  • Longer term semantic preservation research
Key partner: Online Computer Library Center (OCLC)

Other partners included:
  • National Center for Supercomputing Applications (NCSA)
  • the public broadcasting stations, WILL TV and WILL Radio
  • Tufts University
  • Michigan State University
  • the state libraries of Arizona, Connecticut, Illinois, North Carolina, and Wisconsin

Phase II (2008-2010)

The ECHO DEPository received an extension from the Library of Congress for technical architecture work.

Areas of Activity Partners
  • Expansion of repository architecture towards promoting further interoperability
  • Semantic archiving for preservation of meaning as well as structure
  • Development of tools for automating metadata extraction and creation, as well as user evaluation
  • Data format risk assessment and analysis based on the INFORM methodology
  • OCLC
  • NCSA
  • Illinois Department of Computer Science
  • University of Maryland (University of Maryland Institute for Advanced Studies [UMIACS])
