  • In large virtual collections there are always multiple vocabularies
    • In multiple languages
  • Every vocabulary has its own perspective
    • You can’t just merge them
  • But you can use vocabularies jointly by defining a limited set of links
    • “Vocabulary alignment”
  • It is surprising what you can do with just a few links
