Drupal Taxonomy

Drupal taxonomy vocabularies categorize content using singular-named terms and machine names. Design vocabularies for specific purposes—like a `Category` vocabulary with machine name `category` for blog posts—to create organized, filterable content structures and curated landing pages without overcomplicating your data model.

Use taxonomy for simple categorization and term-based landing pages. Use entity references when you need richer data modeling with custom fields, relationships, or attributes. Taxonomy excels at tagging and filtering; entity references suit complex, multi-attribute content organization.

Use singular, concise names that clearly describe purpose. A vocabulary name like `Category` with machine name `category` is clearer than plural forms. Singular naming ensures consistent, predictable naming conventions and improves site maintainability and translation workflows.

Taxonomy should organize content for navigation and curated landing pages, not simple filtering. Apply guardrails in your site-building process: validate that each vocabulary serves a categorization purpose, has clear display patterns, and generates meaningful term pages rather than shallow filter groups.

Drupal taxonomy vocabularies support role-based access control and multi-language translation. Plan term visibility by user role, document translation workflows for multilingual sites, and configure field settings to ensure taxonomy displays correctly across languages and user permissions.
