2. Objectives
Enable the interconnection of learning object
repositories (LORs)
To increase LORs impact in making relevant content
available
By specifying how a network of registries can be set up
with existing standards and specifications

3. Connections to all the networks
querying one registry

11. Use Cases
Template for Use Cases available

12. Data Model
Defines what data the registry will hold about the
repositories
Base ourselves on the IMS LODE registry data model,
which is itself an application profile of ISO2146 -
Registry Services for Libraries and Related
Organizations.

13. Reference Implementation 1
IMS LODE data model
Ariadne Registry deployed for ASPECT & GLOBE
