Taxonomy management is available to users with the Librarian or CloudAdmin role. The full taxonomy is built and maintained in the Tag Browser under Govern.
Namespaces
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.
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.
Merging tags cannot be undone.
Import and export taxonomies
Taxonomies can be imported from CSV via the Tag 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 |
|---|
namespace_label | Yes | Namespace name. Created automatically if it does not already exist. |
namespace_description | No | Namespace description. |
tag_path | Yes | Slash-separated hierarchy (for example, Oncology/Phase-1 creates a Phase-1 tag nested under Oncology). |
tag_description | No | Tag description. |
