Taxonomy Purpose
• Find like items• Improve search results• Disambiguate terms• Differentiate between dissimilar
items

Taxonomy Use
• Used by an author to find and reuse content
• Used by a customer to find and use content
• Label items with terms• Search on those terms• Browse through the terms

Metadata & Taxonomy
• Metadata is data about data, or information about information. We have a shoe, then we have information about the shoe.
• Some of this information can be assigned by the taxonomy.

Basics of Building a Taxonomy
• Do a content audit and assign keywords to each component.
• Pull out all the keywords into one list, then consolidate.
• Decide on your controlled vocabulary.

Ways to Categorize
• Controlled vocabulary refers to an authority list, thesaurus or taxonomy.

Taxonomies
• Hierarchical and faceted• Outlines relationships between items• Used in computer systems to retrieve
non-physical objects.• Images, content components,
documents, videos.

Relationships
• Scope Note• Broader Terms• Related Terms• Narrower Terms• Use• Use For

Hierarchical Taxonomy
• Used when hierarchical structure of items is very important
• Preserves relationships• But can be more difficult to navigate

Hierarchical Taxonomy Example
Hierarchical Flat Format (Thesaurus)

Faceted Taxonomy
• Used when attributes are more important than hierarchy
• Easier to navigate• But can hinder someone looking for
hierarchical relationships• Traditionally one facet value from
each facet (but used more casually outside of libraries)

Taxonomy Review
You may need to teach others how to read and use a taxonomyNeed to work with stakeholders to make sure:• Taxonomy reflects real-world language• BT, RT, and NT are accurate• Nothing is missing• Nothing needs to be removed

Taxonomy Maintenance
• New content always being created• Some of it may not have a “spot”
and needs to be accommodated• Keywords can be promoted to
taxonomy terms• Weekly, monthly, quarterly reviews• Email list for suggestions and
discussion

You, a Taxonomist
• Aware of content• Aware of how people use content
(authors and customers)• Know how to classify information
(think indexing)• One of a few people interested and
good at information organization• Volunteer yourself
