METS and 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

Learning objects

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

•Transmit content from one VLE to another•Import content into a VLE from a resource network, repository or publisher•Export content so that it can be reused by other departments or institutions•Assemble or aggregate existing content into a single package for delivery•Transfer content from an authoring tool to a VLE or repository

METS/IMS-CP convergence

● 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 divergence in approach

Embed IMS-CP <manifest> within METS

Some possible approaches

METSheader

dmdSec

admSec

behaviorSec

structMap

fileSec file inventory

descriptive metadata

administrative metadata

behaviour metadata

structural map

manifest

Some possible approaches

Store learning objects as IMS – generate METS files when needed
