Taxonomies and metadata are used to categorize and structure information in digital environments to help users find content. Taxonomies are an important part of information architecture and user experience design. The task of creating and maintaining taxonomies sometimes falls to UX writers and content designers so it’s good to know what they’re all about.
Definitions
Let’s get a few definitions out of the way:
A taxonomy organizes and structures information, there are generally relationships between the terms of a taxonomy.
A controlled vocabulary is a type of taxonomy. It’s a controlled list of words or terms for a specific purpose like organising a digital library of content. Controlled vocabularies are used to ensure accuracy and consistency in the application of terms to create a frictionless user experience.
Metadata are pieces of information that describe aspects of a digital asset so that asset can be found.

Metadata describes a digital asset so that asset can be found and used. For example, song and album titles, as well as writing credits on Spotify are all examples of metadata:
Another simple everyday example of metadata are hashtags. Whenever you add a hashtag to a Tweet or an Instagram post, you’re using metadata to help other users find your content.
