Information for Learning Object eXchange
Learning Object Repository Registry
LRE Service Center (provided by ASPECT)

Learning Object Discovery & Exchange (IMS LODE)
Aims at facilitating the discovery and retrieval of learning content stored in repositories by establishing practices for combining existing specifications into complete solutions that address the needs of the learning domain

LODE Main Components
Profiles of specifications for learning object discovery:
Open Archives Initiative – Protocol for Metadata Harvesting (OAI-PMH)
Simple Query Interface (SQI)
LOM context set (for CQL and PLQL)
Registry Data Model (based on ISO-2146)
Information for Learning Object eXchange (ILOX)

Adopting Standards and Specifications for Educational Content
30-month Best Practice Network (Sept 08-Feb 11)
European Commission eContentplus program
Aims at
Developing best practice approaches to implementing standards for educational content discovery and use
Improving the adoption of learning technology standards and specifications
Impacting on pre-standardization activities

IMS / ASPECTMemorandum of Understanding
Cooperation on the dissemination and best practice in implementing Common Cartridge
Cooperation in developing region-specific application profiles of IMS specifications and developing conformance tests
Collaboration on IMS LODE

ASPECT and LODE ILOX

LRE Metadata Application Profile v4.0
http://fire.eun.org/LREMAPv4p0.pdf
Based on IMS LODE ILOX + IEEE LOM
Enables
Exchange of resources in multiple formats (web formats, IMS CC, SCORM)
Support for new distribution models
Handling LO descriptions split into several metadata instances (harvesting back of enrichments)

LODE Registry Data Model
Aims at simplifying the management of federation of learning object repositories
Allows for:
Searching for learning object repositories on the basis of their
Metadata collections
Content collections
Supported protocols
Automatically connect to these repositories

ASPECT aims at implementing an OpenSource LODE Registry

LODE Registry XML Binding
Is currently tested by ASPECT (EUN + KUL) to describe the LRE and ARIADNE repositories
Results to be reported this week to IMS LODE during the Redwood meeting

ASPECT Service Center
LOR Registry
Vocabulary Bank
Application Profile Registry
Automatic metadata language translation
Automatic metadata format transformation
Automatic content format transcoding
Compliance testing
Identifier service – handle
Access to known interoperability issues

Automatic Translation
All the LRE metadata have been translated
Translation are limited to LRE metadata (due to SYSTRAN license limitation)
Translations can be harvested using the OAI-PMH target of the LRE

Transformer Service
LREv3.0 -> LREv4.0
LREv4.0 -> LOM
LREv4.0 -> sCMR

Compliance Testing
LRE Metadata v4.0
Core
Recommended

Identity Service

Handle System
“Persistent” identifier for Learning Objects
Stamp (quality label) trusted between LRE members
Can be resolved
Content providers
LRE version of the metadata
Signature verification

LRE Service Center
All the services of the LRE service center provided by ASPECT will be publicly available soon at http://servicecenter.aspect-project.org
