5. What are Taxonomies Good For? • Taxonomies are applied to: • Items: (aka resources) individual pieces of information (documents, people, etc…) • By the use of: • Metadata: (aka properties, attributes) information describing types of data. • Which may or may not use values from a: • Vocabulary: selection of terms, classified or sorted • To create: • Content: an item and its associated metadata Using Taxonomies- Microsoft Knowledge Network Group
