# Knowledge management

> How Tags, Properties, and search work together to make work in Domino findable and reusable.

Knowledge management is how your organization finds and reuses past work instead of reinventing it. Three capabilities carry it: [Tags](/6.3/platform-capabilities/core-concepts/knowledge-management/tags) organize assets under a controlled vocabulary, [Properties](/6.3/platform-capabilities/core-concepts/knowledge-management/properties) document open-ended information about them, and [search](/6.3/platform-capabilities/features/collaboration/domino-search) finds them.

## How it works

Classification is defined centrally and applied by everyone:

* **Tags** categorize assets with values drawn from a controlled, hierarchical list. Namespaces are the allowed keys and Tags the allowed values, so a Project can carry `business-domain:oncology` and `data-sensitivity:confidential` at once.
* **Properties** capture typed information that no fixed list can hold, such as a last-validated date or an internal model ID.
* Admins and Librarians define the tag structure and the available Properties, so classification stays consistent across teams. Everyone applies them to their own assets: Apps, Projects, Project Templates, Datasets, NetApp Volumes, and Models.
* **Search** closes the loop. Global search, entity listing filters, and the Tag Browser surface classified work across the deployment, within each user's permissions. Projects set to **Searchable** appear in results even when their contents stay restricted, so colleagues can discover that relevant work exists and request access.

```

## Choose between tags and properties

Tags organize entities so people can find them. Properties document information about an entity. Pick based on the shape of the value you need to capture:

| Classification                                    | Use        | Why                                       |
| ------------------------------------------------- | ---------- | ----------------------------------------- |
| Risk tier (Low, Medium, High)                     | Tags       | Fixed, controlled set of values           |
| Data sensitivity (Public, Internal, Confidential) | Tags       | Bounded, controlled vocabulary            |
| Department (Marketing, Sales, Engineering)        | Tags       | Controlled list with predictable values   |
| Last validated date                               | Properties | Open-ended date value, varies per asset   |
| Internal model ID                                 | Properties | Free-form identifier unique to each asset |
| Loan portfolio reference                          | Properties | Free-form text that varies per asset      |

Use Tags when the set of allowed values is finite and known in advance: users pick from a controlled list, and parent-child relationships let you model nested categories. Use Properties when the value can't be enumerated up front. Most teams use both, Tags for organization and Properties for documentation.
