6 Inconsistency in vocabulairies Users Function Naming Location Relations Versions Metadata Structure Coverage Communication

7 Vocabulary framework One master set of unique terms (>>5000) Clear classification of terms Vocabularies as collections Clear relations between subsets Chemistry Biology Electrical enignering Geography Boston Dutch Mathematics Human Care Programming Level 2 Level 1 English Water Narrow Term Explain why some people think that Poitiers was a Roman Capital

8 Classification FrameworkEducational Learning objectives LevelsContentOrganizationalTechnical

9 Subjects Secondary education Primary education Vocational education Chemistry Biology Electrical enignering Geography English Dutch Mathematics Vocabularies as Collections Human Care Program ming Science

10 Relations Content Learning objectives Levels Boston 2nd grade secondary education Explain why Boston is important

11 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

12 Vocabularies Geography Narrower Term Cities in England Cities in England Narrower Term Boston Vocabulary –UUIDA Narrower Term UUIDB –UUIDB Narrower Term UUID2
