Manage Domino taxonomies — namespaces, tags, and entity tagging — via the Taxonomy API. Covers creating, listing, updating, and deleting tags and namespaces; tagging entities (project, model, dataset, app, project_template, netapp_volume); querying entities by tag; tag autocomplete; merging tags; and importing/exporting taxonomy trees as CSV. Use when organizing projects with tags, building hierarchical namespaces, finding all entities with a given tag, bulk-tagging during onboarding, or migrating taxonomy across environments.
