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

Addressing the metadata bottleneck …
![Page 7: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/7.jpg)
The Web …
![Page 8: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/8.jpg)
… the library …
![Page 9: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/9.jpg)
… and the ‘bottleneck’
![Page 10: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/10.jpg)
Some possible solutions
![Page 11: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/11.jpg)
More librarians
![Page 12: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/12.jpg)
Automatic tools
![Page 13: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/13.jpg)
Creators, users, volunteers, etc., using custom tools
![Page 14: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/14.jpg)
However, metadata tools for non-experts are not always successful
![Page 15: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/15.jpg)
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?
Metadata tools for non-experts

Context: IPL/LII merger, and IPL2
![Page 17: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/17.jpg)

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)
Context: IPL/LII merger
![Page 19: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/19.jpg)
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

Analysis of Problem Space
IPL cataloging currently requires:
![Page 22: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/22.jpg)
Training materials …

… metadata forms …
![Page 24: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/24.jpg)
… and the resource itself
![Page 25: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/25.jpg)
Cataloging requires multiple windows/tabs
![Page 26: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/26.jpg)
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
User-centered design approach
![Page 27: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/27.jpg)

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/

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
![Page 30: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/30.jpg)
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
![Page 31: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/31.jpg)
Definitions of Metadata
![Page 32: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/32.jpg)
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
![Page 33: Michael Khoo, The iSchool at Drexel ALISE Annual Conference Boston, MA, January 12-25, 2010](https://reader035.fdocuments.us/reader035/viewer/2022062520/568158dd550346895dc62389/html5/thumbnails/33.jpg)
“Surprises”
Students are busy Technology (e.g. Fedora api) is complex Tech staff are busy Existing IPL workflow is complex
