Outline
• A registry! What for?• Functional Requirements for Bibliographic
Records (FRBR)• FRBR & LOM• Describing LOs at Different FRBR Levels• Metadata description in practice• Handling LOM (instead of LOs)• Discussion: ILOX versus OAI-ORE
To federate learning object repositories …
… You need to know where they are …
… And what protocols they support
Current Limitations
• There is no way for a federation such as the LRE to automatically discover new repositories
• The locations of the LRE repositories have to be entered manually
• The knowledge of the protocols supported by repositories for exposing resources is implicit
LOR Registry
IMS LODE Registry Data Model
• Based on the ISO 2146 model for registry description
• Describes:– Content collections– Metadata collections– Protocols– Targets– Access policy
Five Basic Types
1. CharacterString (ex: “apple”)2. Identifier– Catalog (ex: “uri”)– Entry (ex: “http://entity.123.345/567”)
3. LangString– Language (ex: “en”)– String (ex: “apple”)
4. VocabTerm– VocabularyID (ex: “fruit list”)– Value (ex: “apple”)
Five Basic Types (cont.)
5. Property
Strength: “some”, “most”, and “all”
Protocols
SQI
OAI-PMH
