Implementing IMS LODE

David Massart, EUN

SE@M’09

Budapest, Hungary – Nov. 4, 2009

Outline

• IMS LODE• ASPECT• Information for Learning Object eXchange• Learning Object Repository Registry• LRE Service Center (provided by

ASPECT)

Page 3: IMS LODE and the ASPECT project

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

Page 4: IMS LODE and the ASPECT project

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)

Page 5: IMS LODE and the ASPECT project

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

1. Cooperation on the dissemination and best practice in implementing Common Cartridge

2. Cooperation in developing region-specific application profiles of IMS specifications and developing conformance tests

3. Collaboration on IMS LODE

ASPECT and LODE ILOX

Page 8: IMS LODE and the ASPECT project

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

Page 11: IMS LODE and the ASPECT project

ASPECT aims at implementing

an OpenSource LODE Registry

Page 12: IMS LODE and the ASPECT project

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

Page 13: IMS LODE and the ASPECT project

ASPECT Service Center

1. LOR Registry

2. Vocabulary Bank

3. Application Profile Registry

4. Automatic metadata language translation

5. Automatic metadata format transformation

6. Automatic content format transcoding

7. Compliance testing

8. Identifier service – handle

9. 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

Page 16: IMS LODE and the ASPECT project

Transformer Service

• LREv3.0 -> LREv4.0• LREv4.0 -> LOM• LREv4.0 -> sCMR

Page 17: IMS LODE and the ASPECT project

Compliance Testing

• LRE Metadata v4.0– Core– Recommended

Page 18: IMS LODE and the ASPECT project

Identity Service

Page 19: IMS LODE and the ASPECT project

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

Page 20: IMS LODE and the ASPECT project

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
