Note
When you create a metadata catalog, the metadata AI markup is on by default.
With this option enabled, the AI assistant suggests descriptions, domains, classifications and tags, glossaries and terms, and marks up your metadata using them. You can confirm, edit, or reject any suggestion your AI assistant makes by hovering over the AI icon next to the suggestion and selecting the action.
After the catalog is created, you can manage the AI markup on the Overview page or when updating the catalog.
A glossary is a dictionary of domain-specific terms and their definitions. It acts as a single source of truth for terminology used within a company. For more information, see Glossaries and terms.
A domain is a high-level logical group used to organize metadata based on your business process needs, e.g., by departments or business units. For each domain, you can create a subdomain. For more information, see Domains and subdomains.
A classification is a group of tags used to mark up metadata. For more information, see Classifications and tags.
A tag is a label used to mark up metadata by type, e.g., sensitive data or table attributes. For more information, see Classifications and tags.
A term is a concept used to mark up data by its semantic meaning based on an organization’s official definitions, e.g., revenue or expenses. For more information, see Glossaries and terms.
