what are learning objects
What are learning objects?

“a reusable unit of instruction for teaching, typically in e-learning. “ Wikipedia

“small electronic units of educational information that are flexible, reusable, customizable, interoperable, retrievable, facilitate competency-based learning, and increase the value of content” Univ. of Wisconsin

ims content packaging ims cp
IMS Content Packaging (IMS-CP)

“A specification for sending learning objects from one program to another, facilitating easier delivery, reuse and sharing of materials”

CETIS standards briefing

  • Import content into a VLE from a resource network, repository or publisher

METS/IMS-CP convergence

some divergence in approach
Some divergence in approach
  • Content vs. Presentation
    • METS: tends to make strong distinction between content and presentation
    • IMS-CP: presentation is content
    • METS segregates presentation in optional <behaviorSec>, IMS-CP includes it in <manifest>
  • Nonetheless:
    • There are assigned places for content and presentation in each so they can be mapped to each other
some possible approaches
Some possible approaches

Embed IMS-CP <manifest> within METS
