National Library of Canada, Nov. 2002www.cancore.ca2 Overview What CanCore? Rationale for CanCore’s development CanCore’s place in standards evolution Understanding of Learning Objects Repositories, Alliances and Support Future of CanCore
3
National Library of Canada, Nov. 2002www.cancore.ca3 What is CanCore? Based on and fully compatible with the first e- learning standard: IEEE 1484.21.1, LOM 1.0, IMS Meta-data "multi-part Standard to facilitate search, evaluation, acquisition, and use of learning objects…" "also facilitates the sharing and exchange of learning objects, by enabling the development of catalogs and inventories while taking into account the diversity of cultural and lingual contexts in which the learning objects and their metadata are reused."
4
National Library of Canada, Nov. 2002www.cancore.ca4 What is CanCore? Application profile: "customization of a standard to meet the needs particular communities of implementers with common applications requirements." Subset of LOM elements: 77 down to 56; 39 are active Guidelines document: best practice recommendations, 175 pp.

7
National Library of Canada, Nov. 2002www.cancore.ca7 Rationale: Simplicity LOM: leading educational metadata specification LOM Data Model too complicated for effective implementation: "Many vendors [have] expressed little or no interest in developing products that [are] required to support a set of meta-data with over 80 elements" Best Practices and Implementation Guide, IMS, 2000
8
National Library of Canada, Nov. 2002www.cancore.ca8 Rationale: Simplicity LOM Element 5.4 Semantic Density: " The degree of conciseness of a learning object." omitted in CanCore 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."
9
National Library of Canada, Nov. 2002www.cancore.ca9 Rationale Solution: core set of LOM elements most important for exchangeable resource descriptions Mid-way between structuralist (LOM) and minimalist (Dublin Core) approaches to metadata
10
National Library of Canada, Nov. 2002www.cancore.ca10 Rationale: Semantics E-learning specifications & standards communities are largely concerned with syntax and technical interoperation Effective metadata requires semantic specification and consensus Incorporate best practice from library and heritage communities No other body is doing this across e- learning projects
11
National Library of Canada, Nov. 2002www.cancore.ca11 Rationale: Specificity Effective 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

National Library of Canada, Nov. 2002www.cancore.ca18 CanCore and ADL-SCORM Different definitions of “educational objects” Many specifications referenced and combined vs. just metadata Public education vs. training emphases

National Library of Canada, Nov. 2002www.cancore.ca19 The MERLOT Model
20
National Library of Canada, Nov. 2002www.cancore.ca20 Educational Object: Example Content Pedagogical purpose; to augment learning about: Paris 1839 Urban environments Architecture Daguerre Photography Daguerreotypes Granularity: an object can be a course, unit, lesson, image, Web page, exercise, image, multimedia clip; but it must have a specified pedagogical purpose
21
National Library of Canada, Nov. 2002www.cancore.ca21 Learning Objects: Granularity Smaller: Easier: reusability and adapability More difficult: discovery and metadata creation Larger: Easier: discovery and metadata creation More difficult: reusability and adaptibility

24
National Library of Canada, Nov. 2002www.cancore.ca24 Repository Architectures: Access Separate resources and metadata allow for multiple and disparate resource collections to appear as one Metadata must be freely available Combined in a single search set for single- click access Provides a personalized, "portal" solution for the data access problems of the Internet AU tool: staff.icaap.org/careo staff.icaap.org/careo

National Library of Canada, Nov. 2002www.cancore.ca26 CanCore’s Future Update CanCore guidelines document Looking at formal governance issues Looking internationally for collaboration opportunities Looking to establish a permanent office
27
National Library of Canada, Nov. 2002www.cancore.ca27 Conclusion CanCore is the current state of educational metadata development and implementation in Canada “A widespread consensus on a particular protocol which has not been ratified by any official standards body, such as ISO, but which nevertheless has a large market share.” (FOLDOC)
