CI Requirements

The National Science Digital Library (NSDL) aims to enhance educational experiences by allowing instructors to publish, discover, reuse, and directly employ learning objects. This initiative facilitates interactions between providers and consumers of NSDL entities, emphasizing the creation of structuring, recommendation, and classification devices. The implementation philosophy prioritizes collaboration with federated partners and highlights the need for trustworthy resources, educational standards, and robust tools to support the discovery and use of learning materials.

  1. CI Requirements A first stab at...

  2. Purposes • NSDL • To allow instructors to publish, discover, reuse, and directly employ learning objects in education. • CI • To facilitiate interactions between providers and consumers of NSDL entities. Greg Janée • CITI futures kickoff • January 6-7, 2003

  3. NSDL entities • Learning objects • Structuring devices • Recommendation devices • Classification devices • Educational standards • Services • Tools Greg Janée • CITI futures kickoff • January 6-7, 2003

  4. NSDL entities • Learning objects • library’s raison d’ être • reusable, ergo: • self-contained • guaranteed availability, persistence • Structuring devices • collections • series, other hierarchies • lectures, courses, curricula Greg Janée • CITI futures kickoff • January 6-7, 2003

  5. NSDL entities • Recommendation devices • annotations, reviews, usage • must be trustworthy • Classification devices • vocabularies, concept maps, etc. • Educational standards • (what is a standard?) • authoritative? Greg Janée • CITI futures kickoff • January 6-7, 2003

  6. RECOMMENDATIONS learning object RIGHTS Learning object facets • DESCRIPTION • standardized • framework • object-specific • CONTEXT • place in larger structures • classifications • versions Greg Janée • CITI futures kickoff • January 6-7, 2003

  7. Services • Service: • CI-provided services • support all NSDL entities • example: navigation of vocabularies; discovery of terms; robust references to terms • may be specifications only • Other services may be registered A network-accessible, programmatic function that operates on NSDL entities. Greg Janée • CITI futures kickoff • January 6-7, 2003

  8. Tools • Tool: • CI-provided (?) and registered A network-accessible human interface that operates on NSDL entities via services. Greg Janée • CITI futures kickoff • January 6-7, 2003

  9. What’s not in CI? • Communities • already handled by MERLOT, etc. • Specialized interfaces • Tools? • yes: needed to exploit services • no: not infrastructure Greg Janée • CITI futures kickoff • January 6-7, 2003

  10. Implementation philosophy • Limit centrality • Enlist federated partners • currently-funded projects • permanently-funded libraries Greg Janée • CITI futures kickoff • January 6-7, 2003
