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


The metadata bottleneck
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

Metadata tools for non experts
Metadata tools for non-experts successful

  • 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
Context: IPL/LII merger successful

  • 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
User-centered design approach successful

  • Metadata tools have to be carefully designed

  • For the IPL metadata tool, a UCD approach was adopted

    • Interface design

    • Tool content


User centered design approach1
User-centered design approach successful

requirements

refining

development

testing


Analysis of problem space
Analysis of Problem Space successful

  • IPL cataloging currently requires:






User centered design approach2
User-centered design approach successful

  • 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 approach3
User-centered design approach successful

  • 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
Content Analysis successful

  • 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 analysis1
Content Analysis successful

  • 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
Final tool will: successful

  • 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
“Surprises” successful

  • Students are busy

  • Technology (e.g. Fedora api) is complex

  • Tech staff are busy

  • Existing IPL workflow is complex
