Why Sakai?• Sakai is open, extensible platform that supports
customization, development, rapid advancement
• Matches many existing CourseWorks features
• Has desired features not found in CourseWorks
• Community Development Model (with our peers)
• Leverages existing standards

Library/Repository Roles
• Library offers consistent metadata for all items used by the instructor
• Library should offer consistent service interfaces
• What are the right services? (e.g., Sakai twin peaks for search-type discovery)

Decisions
• Repository definition / collection scope
• Service definition
• Acquisition/publication definition
• Delivery to non-web-browsers (software agents, mobile devices)
• Services, not web sites?
Millman -- 2006 April -- 15
Personal Library vs. Research Library (Print)
• Individual selection criteria
• Personal shelving system understood only by individual
• Decision to lend material made by library owner
• No backup preservation
• Professional selectors in each field
• Standardized systems for cataloging and retrieval
• Lending policies and tracking system for distribution of content
• Duplicate copies in multiple libraries
Millman -- 2006 April -- 16
Individual Web-Environments vs. Scalable Digital Library
Resources• Develop individual digital teaching
tool
• Broad range of approaches to citation and permissions
• Individual systems for tagging content
• Organize digital content for individual class
• Storage and access dependent on individual author
• Organize libraries of digital resources for reuse
• System to standardize citation and track IPR
• Consistent metadata enforced by workflow rules
• Automatic correlation of digital resources to general conceptual structures and standards
• Reliable access and archiving
Millman -- 2006 April -- 17
More Next Steps
• Journal of Jazz Studies (Fall ’06, Ford Foundation funding)
• Investigate service requirements through workflow
• “Spectrum of stability”
Millman -- 2006 April -- 18

Millman -- 2006 April -- 19
Research Questions
• How many discrete stages?
• What features are appropriate at each stage?
• What actions happen as content crosses stage boundaries?
• Can we create service requirements from these features?
Millman -- 2006 April -- 20
Immediate future
• Analysis, opportunity, leverage existing technologies & skills
• Incremental and iterative
• Research projects
• Socialization
• Policy
