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

However, metadata tools for non-experts are not always successful
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?
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)
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
User-centered design approach requirements refining development testing
Analysis of Problem Space • IPL cataloging currently requires:
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
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
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
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
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
“Surprises” • Students are busy • Technology (e.g. Fedora api) is complex • Tech staff are busy • Existing IPL workflow is complex
