2. L3S Hannover February 6, 2004www.cancore.org2 Overview What is CanCore? Why CanCore? CanCore’s metadata guidelines Other CanCore/AU aids for implementers Related Canadian projects

3. L3S Hannover February 6, 2004www.cancore.org3 What is CanCore? Learning Object Metadata – standard: IEEE 1484.12.1 - 2002 Is complex, general and ambiguous CanCore reduces complexity & ambiguity Provides guidance on low level of detail Look to solutions from library and information management world Guidelines for all 76 LOM elements

4. L3S Hannover February 6, 2004www.cancore.org4 What is CanCore? Application profile: "customization of a standard to meet the needs of particular communities with common applications requirements." Subset of LOM elements: 76 down to 56; 39 are "active" Guidelines document: best practice recommendations, 200 pages

5. L3S Hannover February 6, 2004www.cancore.org5 Rationale: Semantics E-learning specifications & standards communities are largely concerned with syntax and technical interoperation Effective metadata use requires semantic specification and consensus Incorporate best practice from library and heritage communities This is not otherwise done across e- learning projects

6. L3S Hannover February 6, 2004www.cancore.org6 Rationale: Simplicity LOM Element 5.4 Semantic Density: " The degree of conciseness of a learning object." Recommends ways of calculating it; omitting it LOM Element 1.2 Title "Name given to this learning object." Word order, subtitles, multilingual titles, series/episode titles LOM Classification Element Group " Describes where this learning object falls within a particular classification system."

7. L3S Hannover February 6, 2004www.cancore.org7 Rationale: Semantics The LOM framework leaves gaps.

8. L3S Hannover February 6, 2004www.cancore.org8 Rationale: Semantics CanCore fills in the gaps.

9. L3S Hannover February 6, 2004www.cancore.org9 Rationale: Specificity implementation requires a consistent interpretation of each element’s purpose and use Realize economy of scale by coordinating the implementation and interpretation of metadata for a number of learning object repository projects The range of implementations has consistently expanded

10. L3S Hannover February 6, 2004www.cancore.org10 Rationale: Overview LOM Data Model: 76 elements, little interpretation Complexity decreases Specificity and Interoperability increases
