Today along with our brief we also talked about taxonomies, and what is meant by different content types.
The term taxonomy gets applied across a range of contexts. In the biology world, it means grouping organisms into hierarchical groups (e.g., kingdom, phylum, class, order, family, genus, and species).
The web/digital world typically applies it to any kind of structure that organises information. Information science people sometimes say “controlled vocabularies” instead of taxonomies. Regardless of the term, the underlying goals are to create some level of consistency and control over the information used to describe a content component, and clarify relationships between them.
Common types include:
- Term list: A standardised list of terms created to insure consistent tagging and indexing. Think of it as a list of “preferred language.” Term lists typically provide a series of metadata values to pick from for elements like format or content type.
- Hierarchies: Often called a “taxonomy,” a hierarchy defines the structural framework used to classify terms into parent/child or broad-to-narrow relationships. Hierarchies are specifically used to support layered groups of information and not simply for the convenience of creating groupings—although each level of a hierarchy is commonly referred to as a “category.”
- Thesauri: A thesaurus translates conceptual relationships between the content, often made naturally by humans, into something a computer can understand. Thesauri typically address three types of relationships: equivalent (synonyms), hierarchical (broad-to-narrow terms), and/or associative (related terms.
