An infrastructure for exchanging learning resources

Brief history

Collecting metadata

Exposing learning resources

Where does it hurt?

Metadata management

Sharing mine and reusing yours (it’s not technical)

By the way

Glossary Learning Resource: Anything digital used for learning and/or teaching Learning Resource Metadata: Machine-readable description of learning resources Learning Resource Repository: Software system for managing learning resources and/or their metadata

Learning Resource:

Anything digital used for learning and/or teaching

Learning Resource Metadata:

Machine-readable description of learning resources

Learning Resource Repository:

Software system for managing learning resources and/or their metadata

Learning Resource Exchange An infrastructure for Federating applications that provide learning resources (e.g., learning resource repositories, authoring tools) Offering a seamless access to these resources to educational applications that consume them (e.g., educational portals, VLEs)

An infrastructure for

Federating applications that provide learning resources (e.g., learning resource repositories, authoring tools)

A Brief History of the LRE ETB: Dublin Core, NNTP => LRE Thesaurus CELEBRATE: LOM, Brokerage System (JMS + WS) => Simple Query Interface (SQI) + LRE Application Profile (LRE AP) FIRE: LOM, SQI Brokerage System => S 2 QL CALIBRATE: LRE AP, SQI + OAI-PMH Brokerage System, S 2 QL => PLQL MELT: Service-Oriented Architecture => >150,000 open resources + Metadata ASPECT:  Much more to come 

ETB: Dublin Core, NNTP => LRE Thesaurus

CELEBRATE: LOM, Brokerage System (JMS + WS) => Simple Query Interface (SQI) + LRE Application Profile (LRE AP)

FIRE: LOM, SQI Brokerage System => S 2 QL

CALIBRATE: LRE AP, SQI + OAI-PMH Brokerage System, S 2 QL => PLQL

MELT: Service-Oriented Architecture => >150,000 open resources + Metadata

ASPECT:  Much more to come 

Where Does It Hurt? Metadata & resource management Sharing my resources is easy but Reusing yours is a pain!
