Topic Taxonomy Setup & Use

In this guide you'll learn what makes "topic" taxonomies different from other kinds of taxonomy structures, like type or faceted taxonomies, and you'll learn how to set up a topic taxonomy in the Sanity Taxonomy Manager plugin. You'll also see examples of how to integrate your taxonomy into document schemes and query across related concepts for tagged documents.

Topic classification is often used to provide multiple pathways to a concept, article, or product. In the example from the Smithsonian Institute above, any of a dozen or so Topics eventually lead one to the Smithsonian's archival record on Francis Gary Powers.

Topic classification is also a powerful way to express brand differentiation. Columbia and Patagonia both make and sell a similar range of outdoor activity apparel for adults and kids, and products for both companies fall into clearly delineated types: jackets, shirts, base layers, pants, etc. Topical grouping on each site (which, when at the top level we usually call "categories") tell users of each site what kind of "place" it is.

• Relationships: Topic taxonomies may only be a singe level, or comparatively shallow, and often combine parent-child "is-a" and whole-part "has-a" relationships freely.
• Adaptability: Topic taxonomies are much more flexible than "type" taxonomies, and can be used to express a brand's (or user's) particular perspective.
• Size Limitations: Topic taxonomies are often are not very large: because the relationships are less strict than in many Type taxonomies, large structures in Topic taxonomies may end up hiding concepts in categories users may not expect.

Not all Topic and Category vocabularies need to be managed as a formal, standards-based taxonomy. If you're Mud Bay, a health-focused pet food and supplies store with products mostly for dogs and cats, a category list of "dog," "cat," and "small animal" (everything else) stored in your CMS may work just fine. If you're Chewey.com, however, and you carry retail and pharmacy supplies for dogs, cats, fish, birds, reptiles, farm animals, and more, you'll likely see usability, governance, and scale efficiencies by managing your topic taxonomy more formally.

You may also consider formally modeling and managing your topics if you're sharing them between systems, such as a CMS, a PIM, and/or a CRM. Formal modeling may also be beneficial if you're combining your topics with other formal structures (such as type or faceted taxonomies) to generate recommendations and insight from user behavior, or to provide AI tools the ground truth they need to return reliable, trustworthy results.

The Taxonomy Manager plugin allows you to create standards compliant relationships that help keep your taxonomy interoperable and reusable.

Concept Schemes are used to create multiple taxonomies in a single project, and, where needed use the same concepts across them. This gives you a single source of truth for each concept you define, and allows you to establish semantic relationships between individual taxonomies.

Add a new Concept Scheme with either the global "new document" button, or the "new document" button in the Concept Schemes list view

Add a clear name and describe the purpose and goals of your taxonomy to users. Tagging content with managed terms may be new to your content creators: good descriptions can help users understand why the tagging step is important.

For small or non-hierarchical lists of topics, you may elect not to use Top Concepts at the highest level of the hierarchy. This can be a good option when you have a flat list, or some concepts without child concepts, or when you're going to want users to be able to select any term for tagging (including those at the highest level).

Child concepts may be narrower types, or individual parts of a larger whole.

You're now ready to publish your taxonomy, integrate it into your content scheme, and start tagging content. Taxonomy Manager includes two helper functions for ensuring that only the appropriate concepts are available for a given field:

• Scheme Filter: affords access any term in the designated Concept Scheme
• Branch Filter: affords access to terms in a specific branch of a designated Concept Scheme
• Docs: Adding Schemes to documents

Once your content is tagged, the semantics built into your topic taxonomy allow you to retrieve all topics related to a resource, retrieve all resources tagged with a given topic (or topics), or create a list or resources by topic and/or subtopic (for example, to help in the creation of topic-based navigation).

*[_type == "post" && "Snowshoeing" in topic[]->prefLabel]

[_type == "post" && "a675a1" in topic[]->conceptId]

Each concept you create in Taxonomy Manager is automatically given a unique conceptId. You can find the conceptId below the Base URI field in the concept editor pane:

*[_type == "post" && title == "Best Base Layers for Snow Sports"]{
  title,
  "topics": topic[]->prefLabel
}

*[_type == "skosConceptScheme" && schemeId == "04ab34"].concepts[]->{
  "topic": prefLabel,
  "articles": *[_type == "post" && references(^._id)].title
}

Well defined, standards compliant taxonomy provides a ground truth foundation for scores of different discovery, personalization, and business intelligence applications. The queries above offer just a few examples of how assiduously applied taxonomy can help you manage content based on the relationships you've created. Your dataset, taxonomy, and goals will be the most natural drivers for how your taxonomies are used to create value.
