• Share of metadata creation declines
• Become peripheral to major activities in information management for research and learning
• Increasingly marginal to many ‘digital library’ initiatives on campus
• Lose potentially valuable ‘reference’ resources
Next stepsNext steps

– Learning objects
– Contentdm
• KONA– Under development
• Schema trans– Investigation
• Will work with CMS
• Exploratory
