Questions.. to think about
• How to deal with the meaning of terms in vocabularies?
• Related experiences, research?
Vocabularies used for
• Labelling Learning resources • Searching and finding• Interoperability between educational collections
(50+)• Data exchange between schools and
government• Structuring content in Virtual Learning
Environments• Monitoring learners• Data exchange test results

Semantic vocabularies
• Terms with multiple meanings like Boston– Each meaning a unique identifier– Terms have a shared caption– Shared captions are also used as identifier– Describing learning materials most specific
• ID: UUID1• Description: Boston the city in England• Caption; Boston• Classification: Content
• ID: UUID2• Description: Boston the band• Caption; Boston• Classification: Content
Vocabularies
