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)

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

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)

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

So Where and When Should We Apply Metadata?

Begs more questions1. For which content should we develop and

apply metadata?

2. How qualified/experienced are those who own content/apply that metadata?

3. Which metadata attributes should we develop?

4. Which metadata vocabularies should be controlled?

Selecting Content for Metadata: The Value Tier ApproachDetermine value tiers of content quality

that make sense given your users/content/context

How to do it?1.Prioritize and weight quality criteria for

different content areas2.Rate content areas (subjectively and

objectively)3.Cluster into tiers
