Taxonomy management is available to users with the Librarian or CloudAdmin role. The full taxonomy is built and maintained in the Knowledge Browser under Govern.
A namespace is a top-level grouping of related tags — for example, business-domain, data-sensitivity, or project-status.
Namespace labels are alphanumeric and support hyphens and underscores.

Important
| Each namespace has an independent assignment policy: when Allow multiple tags per entity is off (the default), an entity can hold only one tag from that namespace at a time. |
Tags live within a namespace and support hierarchical organization through parent-child relationships. A tag can be created as a root-level entry or nested under an existing tag.
Tags can be edited or deprecated at any time. A deprecated tag remains on any entities currently assigned to it but cannot be applied to new ones — useful for retiring a classification without breaking existing assignments.
Taxonomies can be imported from CSV via the Knowledge Browser — useful for migrations or bootstrapping from an existing spreadsheet or external provider. Export is available via the Taxonomy API and returns the full taxonomy as a CSV file, suitable for backup or seeding another environment. Download a sample import file to get started.
Each row in the import file defines one tag. The file has no header row. The columns are:
namespace_label,namespace_description,tag_path,tag_description| Column | Required | Description |
|---|---|---|
| Yes | Namespace name. Created automatically if it does not already exist. |
| No | Namespace description. |
| Yes | Slash-separated hierarchy (for example, |
| No | Tag description. |
The import preview flags any rows with errors before anything is committed.
