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
