  1. DCMI 2003 Pre-Conference Workshop: Metadata and Search DC-2003 Seattle, Washington September 28, 2003 Louis Rosenfeld www.louisrosenfeld.com

  2. I Am… • Information architecture (IA) consultant; formerly president Argus Associates • Co-author, Information Architecture for the World Wide Web (1998, 2002) • Co-founder and Director, Asilomar Institute for Information Architecture (www.aifia.org) • Background in librarianship/information science; Fortune 500 bias

  3. Metadata:The Post-Cathartic Perspective • “Meta-data is not just about structured data anymore.” • -- Robert Seiner • Publisher, The Data Administration Newsletter • (http://www.tdan.com/i024fe01.htm, 4/03)

  4. Metadata:The Weary Soldier’s Perspective • “I've decided that good metadata is too expensive for most documents. If you can get an effective title and date on all your important documents, you should declare victory and go out for a beer.” • -- Walter Underwood • Principal Architect, Verity Ultraseek • (Personal communication, 9/03)

  5. Metadata: The All-Too-Common Perspective • “Our information management and access problems will be solved by push search engine personalization CMS implementation metadata.” • -- Anonymous CIO • Megacorp • Sometime during the Early Web Age

  6. Diagnosis: A malady called Silverbulletitis • Common affliction among senior managers • Evidenced by • Single-minded preoccupation with a specific technology or approach • Belief that such an approach comprises a solution • Constant presence of product literature, pens, mugs, plush toys, and other assorted vendor schwag

  7. Metadata as Silver Bullet:Think again • Inter-cataloger inconsistency (Medline study) • Approximately 10% of humanly assigned index terms do not occur in full text; worth the investment to address? • Structural interoperability of metadata attributes (DC can help) • Semantic merging of metadata values (significant challenge)

  8. Metadata in Business Setting:Think again • Business cultures not used to cooperating • Time on task: e.g., six minutes per document X 1M documents = 62.5 FTE for one year • Lack of best practices for centralized services (e.g., tagging) • Lack of robust tools for metadata management (whither MMS?) • Lack of expertise: non-pros doing the work

  9. Metadata: Part of the Answer Available from: http://www.louisrosenfeld.com/home/bloug_archive/images/EIAroadmap.pdf

  10. So Where and When Should We Apply Metadata? • Begs more questions • For which content should we develop and apply metadata? • How qualified/experienced are those who own content/apply that metadata? • Which metadata attributes should we develop? • Which metadata vocabularies should be controlled?

  11. Selecting Content for Metadata: The Value Tier Approach • Determine value tiers of content quality that make sense given your users/content/context • How to do it? • Prioritize and weight quality criteria for different content areas • Rate content areas (subjectively and objectively) • Cluster into tiers

  12. The Value Tier Approach:Potential quality criteria • Select appropriate criteria for your business context, users, and content • Authority • Strategic value • Currency • Freshness • Usability • Popularity/usage • Feasibility • Presence of quality existing metadata

  13. Value Tier Approach:Weighting and scoring

  14. Value Tier Approach:Prioritization

  15. Content Workflow:Process and ownership • Evaluate content management centralization, owner sophistication • Integrate results into content value tiers

  16. Attribute Selection:Match content, appropriate subset

  17. Controlled Vocabularies:CV or not CV?
