issues for educational objects
Issues for Educational Objects
  • Electronic format needs to be readable by both machines and humans
  • Metadata needs to be created by non-librarians
  • Need to describe educational aspects of resources
metadata what it is
Metadata: What it is
  • Dublin Core Metadata Initiative
    • 15 Elements; all “core”
    • No confirmed elements for education
  • IEEE LOM
    • 76 Elements
    • Clear leader in metadata for educational objects
problems with the lom
Problems with the LOM
  • Too few core elements
  • Too many optional elements
  • Ambiguities in definitions
  • No guidelines or interpretations available for implementation
    • be careful if someone says they’re using IMS for their resources
what it will be cancore
What it will be; CanCore
  • Establishes a core of 43 LOM elements
  • CanCore established for the purposes of sharing data between collections
  • Will provide guidelines and interpretations that will address ambiguities and facilitate implementation
cancore con t
CanCore Con’t
  • Is being used in the architecture of the national EduSource projects
  • Funding and support from:
    • Netera Alliance
    • TeleCampus.edu
    • Electronic Text Centre at UNB
  • Alberta Learning
cancore benefits
CanCore: Benefits
  • Architecture: Easy sharing of resources across collections
  • User: Seamless, single-click access to wide variety of resources
cancore con t1
CanCore, Con’t
  • There are degrees of compliance with CanCore (or any metadata standard)
  • The more of CanCore (elements and guidelines for their use) that can be utilized, the greater the seamlessness of resource use can be expected & greater discoverability
next steps
Next Steps
  • Finalize draft of element descriptions and guidelines
  • Establish subject vocabularies for K-12, university, and technical institutions in the province
  • Establish advisory & maintenance roles for metadata
