The Connecticut Digital Archive (CTDA) provides digital preservation and presentation services for cultural heritage organizations in Connecticut. It aims to ensure digital resources created today remain accessible in the future. The CTDA stores content from UConn, state agencies, and other organizations. It offers secure storage, file format migration, and indexing of content in search engines and the Digital Public Library of America. Organizations retain ownership of content while benefitting from the CTDA's services and stewardship of digital cultural heritage in Connecticut.
Introduction to the CTDA
- 1. The Connecticut Digital Archive: Preservation and Presentation Services for Cultural Heritage Organizations March, 2014
- 2. The Dilemma of Modern Records How do we insure that resources that exist in digital form today will reliably exist and be accessible in the future? 2???2014 ??
- 3. • Digital representations of analog originals • Born digital objects with no inherent “original “form • Still Images • Data Sets • Documents • Moving Images • Complex objects Digital repositories organize data…
- 4. ..allow it to be used in one environment …
- 5. … and reused in another.
- 6. -James Gleick, The Information: A History, A Theory, A Flood (2011) "When it was made simple, counted in bits, information was found to be everywhere” "It is not just about the data, it is about the story" -Arianna Huffington (2012)
- 7. Content = Data Analog = Non-existent Unconnected = Invisible Reuseable = Valuable Storytelling = Visualization Five Equations of the Cultural Record
- 8. Four “-ities” of Digital Repositories • Sustainability The digital object can be maintained and accessed over time • Authenticity The digital object is reliably true to the original • Interoperability The ability of one standards-based object to be used in any other standards-based system • Reusability Objects can be used in ways not related to original purpose
- 9. Connecticut’s digital cultural heritage is: • Ephemeral • Fragmented • Not easily discoverable or reusable
- 10. What is the CTDA? • A service of the University of Connecticut Libraries • A partnership with the Connecticut State Library • Preserves, manages, and makes available permanently valuable digital data produced and collected at UConn, Connecticut State agencies, and cultural heritage organizations throughout the state • The service hub in Connecticut for the Digital Public Library of America
- 11. Use Only What You Need: • No particular administrative workflow or end-user application is assumed or required. • No particular catalog or organizational scheme is assumed or required. • Any number of indices and views, designed for specific purposes, both administrative and public facing, can be applied to any pattern of components or objects.
