  1. Addressing the Metadata Bottleneck* *By Developing and Evaluating an Online Tool to Support Non-specialists to Evaluate Dublin Core Metadata Records Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010

  2. The Metadata Bottleneck The Metadata Bottleneck • The Web is a rich source of digital resources • Quality metadata = quality repositories • The number of resources needing metadata > number of people making metadata • There is a metadata bottleneck or gap in the way of quality digital repository development

  3. The Metadata Bottleneck The Metadata Bottleneck • The Web is a rich source of digital resources • Quality metadata = quality repositories • The number of resources needing metadata > number of people making metadata • There is a metadata bottleneck or gap in the way of quality digital repository development

  4. The Metadata Bottleneck The Metadata Bottleneck • The Web is a rich source of digital resources • Quality metadata = quality repositories • The number of resources needing metadata > number of people making metadata • There is a metadata bottleneck or gap in the way of quality digital repository development

  6. Addressing the metadata bottleneck …

  7. The Web …

  8. … the library …

  9. … and the ‘bottleneck’

  10. Some possible solutions

  11. More librarians

  12. Automatic tools

  13. Creators, users, volunteers, etc., using custom tools

  14. However, metadata tools for non-experts are not always successful

  15. Metadata tools for non-experts • Identified problems: • Poor communication of knowledge and instruction • Poor interface design • Poor usability • Useful to continue to have a professional cataloger dimension (support, QA, etc.) • How can users be better supported?

  16. Context: IPL/LII merger, and IPL2

  17. Context: IPL/LII merger • IPL & LII metadata crosswalked to Dublin Core • This required a new metadata admin tool • Tool will be used by students in iSchool classes to practice metadata generation and contribute metadata to IPL2 • Students are ‘non-experts’ (for now)

  18. User-centered design approach • Metadata tools have to be carefully designed • For the IPL metadata tool, a UCD approach was adopted • Interface design • Tool content

  19. User-centered design approach requirements refining development testing

  20. Analysis of Problem Space • IPL cataloging currently requires:

  21. Training materials …

  22. … metadata forms …

  23. … and the resource itself

  24. Cataloging requires multiple windows/tabs

  25. User-centered design approach • Graduate HCI class at Drexel • IPL introduced as ‘client’ (real world example) • Metadata tool as the design brief • Student teams worked on • Requirements gathering • Paper prototyping • Usability testing • Prototype refining

  26. User-centered design approach • Students developed several prototypes, and a hybrid was subsequently developed further • http://research.cis.drexel.edu/test/ipl/ipl.html • file:///Users/mkhoo/Desktop/Work/10%20ALISE/tool_01%20copy/ipl.html

  27. Content Analysis • Aims • Identify key concepts in metadata experts’ discourse • Identify student conceptions • Provide useful instructions to bridge the two • Only the first analysis (key concepts for metadata experts) undertaken so far

  28. Content Analysis • Identify online/digital guides to and descriptions of metadata • Convert to text files and analyze with Centering Resonance Analysis (CRA) software • Output as graphs and ranked indices

  29. Definitions of Metadata

  30. Final tool will: • Integrate multiple windows (rubric, record, resource) into one interface • Explain complex metadata concepts to non-specialist users • Support usability with iterative user-centered HCI

  31. “Surprises” • Students are busy • Technology (e.g. Fedora api) is complex • Tech staff are busy • Existing IPL workflow is complex
