Hugo includes support for user-defined groupings of content called taxonomies.1 Taxonomies give us a way to classify our content so we can demonstrate relationships in a variety of logical ways.
The default taxonomies for Hugo are tags and categories. These taxonomies are common to many website systems (e.g. WordPress, Drupal, Jekyll). Unlike all of those systems, Hugo makes it trivial to customize the taxonomies you will be using for your site however you wish. Another good use for taxonomies is to group a set of posts into a series. Other common uses would include categories, tags, groups, series and many more.
When taxonomies are used (and templates are provided), Hugo will automatically create pages listing all of the taxonomies, their terms and all of the content attached to those terms.
Taxonomy: A categorization that can be used to classify content
Term: A key within that taxonomy
Value: A piece of content assigned to that Term
For example, if I was writing about movies, I may want the following taxonomies:
I would then specify in each movie’s front-matter the specific terms for each of those taxonomies. Hugo would then automatically create pages for each Actor, Director, Studio, Genre, Year and Award listing all of the Movies that matched that specific Actor, Director, etc.
Let’s use an example to demonstrate the different labels in action. From the perspective of the taxonomy, it could be visualized as:
Actor <- Taxonomy Bruce Willis <- Term The Six Sense <- Content Unbreakable <- Content Moonrise Kingdom <- Content Samuel L. Jackson <- Term Unbreakable <- Content The Avengers <- Content xXx <- Content
From the perspective of the content, it would appear differently, though the data and labels used are the same:
Unbreakable <- Content Actors <- Taxonomy Bruce Willis <- Term Samuel L. Jackson <- Term Director <- Taxonomy M. Night Shyamalan <- Term ... Moonrise Kingdom <- Content Actors <- Taxonomy Bruce Willis <- Term Bill Murray <- Term Director <- Taxonomy Wes Anderson <- Term ...
- Taxonomies were called indexes in Hugo prior to v0.11. [return]
