  8. 8. Online controlled vocabularies ● What are they? ○ A collection of concepts for populating a given metadata field
  9. 9. Online controlled vocabularies ● What are they? ○ A collection of concepts for populating a given metadata field ○ Ensure consistent spellings & syntax
  10. 10. Online controlled vocabularies ● What are they? ○ A collection of concepts for populating a given metadata field ○ Ensure consistent spellings & syntax ○ Prevent metadata misunderstandings
  11. 11. Online controlled vocabularies ● What are they? ○ A collection of concepts for populating a given metadata field ○ Ensure consistent spellings & syntax ○ Prevent metadata misunderstandings ○ Maintain a static relationship between metadata fields and the real world
  12. 12. Online controlled vocabularies ● What are they? ○ A collection of concepts for populating a given metadata field ○ Ensure consistent spellings & syntax ○ Prevent metadata misunderstandings ○ Maintain a static relationship between metadata fields and the real world ○ Concepts from different controlled vocabularies may be connected using simple mapping relationships
  13. 13. Online controlled vocabularies ● What are they? ○ A collection of concepts for populating a given metadata field ○ Ensure consistent spellings & syntax ○ Prevent metadata misunderstandings ○ Maintain a static relationship between metadata fields and the real world ○ Concepts from different controlled vocabularies may be connected using simple mapping relationships ○ Web accessible - you can browse to them
