# Tag Schema

Tagging Schemas refers to the practice of attaching descriptive labels or metadata to schemas. Tags provide a way to categorize, organize, and search for schemas based on their characteristics, attributes, or purposes. Tagging schemas in Guardian helps users easily identify and manage schemas based on their specific needs or criteria.
