This helps people find and reuse institutional knowledge, and avoid reinventing the wheel. The taxonomy system works by letting you assign key-value style tags to different assets in the platform. The taxonomy is composed of two core concepts: * **Namespaces** are the allowed keys that make up your key-value tags. * **Tags** are the values allowed within a given Namespace. Think of Namespaces as the category or dimension you use to classify something, and Tags as the allowed values each category can take on.

Once you’ve created your taxonomy, you can apply tags to different entities in the platform and search and browse assets by tag. ## Get started * [Apply Tags](/cloud/platform-capabilities/features/knowledge-management/apply-tags): Assign tags to your Apps, Projects, Project Templates, Datasets, and NetApp Volumes. * [Browse Assets](/cloud/platform-capabilities/features/knowledge-management/browse-assets): Find tagged assets across the Tag Browser, search, and entity-specific views. ## For admins and librarians * [Manage Taxonomies](/cloud/platform-capabilities/features/knowledge-management/manage-taxonomies): Build and maintain the taxonomy structure, import from CSV, and merge tags.
