Outline - What are:
• Learning Objects
• Learning Object Repositories
• LOR projects underway internationally
• LOR projects underway in Canada: the EduSource Project
What are Learning Objects?
• Any digital resource that can be reused for the purposes of teaching and learning.
• Why learning objects?"stand-alone applications are incompatible with typical production, distribution, and usage patterns for educational software."
J. Roschelle, et.al.
What are Learning Objects?
• Reusable
• Modular
• Free and at cost
• Flexible
• Portable
• Interoperable
• Annotation, adding value
What are Learning Object Repositories?
A collection of digital assets and/or meta-data accessible without prior knowledge of the repository’s structure through a interoperable functions via a network.
•Adapted from IMS Digital Repositories Interoperability Specification
– Assets and metadata can be separate– To prevent "silos" or "stovepipes"
What are Learning Object Repositories?
What are Learning Object Repositories?
• 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

LOR's underway Internationally
LOR projects underway in Canada: POOL Project
• Portal for Online Objects in Learning
• P2P and RDF – cooperating with Edutella
• Based on the JXTA P2P protocol
• Splash, Pond, Pool repository “nodes”
• www.edusplash.net
POOL: Peer-to-Peer
Splash Interface
LOR projects underway in Canada: BELLE-CAREO
• Broadband-Enabled Lifelong Learning Environment• Campus Alberta Repository of Educational Objects• Repository with a client-server architecture• Metadata store; objects store is both central and
distributed• Using content packaging to provide a way of
exchanging and accessing parts of aggregate objects
• +2500 objects
LOR projects underway in Canada:CAREO/ALOHA
• CAREO: Web portal of repositories
• ALOHA: Java client for metadata creation and cross-repository searching
• 3000 learning objects
