TodayToday

The use of learning (content) management systems is common in most educational organizations

Huge number of educational resources available on-line, for free or by subscription

Most of these resources are hidden in repositories, which hampers their potential use and reuse

Several initiatives aim at federating e-learning systems to unlock the educational content hidden in their repositories The EUN Learning Resource Exchange GLOBE CORDRA

BUT ...BUT ...

No agreed profiles address the needs of the learning domain

No established practices for combining existing specifications into complete solutions

Individual organizations (GLOBE, LRE, CORDRA) are creating their own solutions, and an opportunity to establish broader interoperability is being missed

There is no way of measuring or testing the compatibility and conformance of specific solutions

Aims to facilitate the discovery and retrieval of learning content stored in repositories

Examines, selects, and adapts specifications that are being applied to digital libraries, generic repositories, and learning repositories

Defines a small number of scenarios for the discovery and exchange of learning resources (e.g., federated searching, harvesting, etc.)

Will produce: A set of specification profiles to support the scenarios Sample implementation(s) A conformance domain-profile

LODE versus Other IMS SpecsLODE versus Other IMS Specs

Current IMS specs Make it easier to exchange and reuse learning

content (e.g., QTI, Common Cartridge, Content Packaging)

Allow specific types of content to be transferred between systems and reused

Aide discovery by unifying the descriptions of content (e.g., Metadata, VDEX)

Do not address the issue of how this content can be found

Missing piece: A protocol to support the discovery and exchange of interoperable content
