# Manage Classification
Add and manage classifications in OpenMetadata to organize how data assets are tagged across your organization. This includes creating a new classification, editing its details, deleting one you no longer need, and exporting or importing its tags in bulk using a CSV file.
## Add a Classification
To create a new classification:
1. Navigate to **Govern** > **Classification**.
2. Click **Add Classification**.
3. Fill in the following details:
* **Name** (required): A unique name for the classification.
* **Display Name**: A human-friendly label shown in the UI.
* **Description** (required): Describe what this classification is used for.
* **Mutually Exclusive**: When enabled, only one tag from this classification can be assigned to a data asset at a time. For example, an asset can be tagged as either `PII-Sensitive` or `PII-NonSensitive`, but not both.
* **Owners**: Search for and assign one or more teams or users as owners of the classification.
* **Domains**: Search for and assign one or more domains to the classification.
4. Click **Save**.
## Add Tags to a Classification
After a classification is created, add tags under it:
1. Select the Classification from the **Classification** page.
2. Click **Add Tag**.
3. Fill in the following details:
* **Name** (required): A unique name for the tag.
* **Display Name**: A human-friendly label shown in the UI.
* **Icon**: Pick an icon to represent the tag.
* **Color**: Pick a color swatch for the tag's icon.
* **Description** (required): Describe what the tag means, using the rich text editor.
* **Owners**: Search for and assign one or more teams or users as owners of the tag.
* **Domains**: Search for and assign one or more domains to the tag.
4. Click **Save**.
The pencil icon next to **Description** on a classification's or tag's page also allows a quick inline edit, and the tag table has an **Enabled** toggle for each tag.
Select the Classification, then click the **⋮** icon in the top right to open the menu with **Edit**, **Import**, **Export**, and **Delete** options.
## Edit a Classification
Update a classification's details after it's created:
1. Select the Classification you want to update.
2. Click the **⋮** icon and select **Edit**. This opens the same form as [Add a Classification](#add-a-classification), pre-filled with the current values.
3. Update any field and click **Save**.
`Name` cannot be changed for **system** classifications (such as `PII` and `Tiers`) after they're created.
## Import Tags into a Classification
OpenMetadata supports classification import to save time and effort by uploading a CSV with several tags in one go, creating or updating multiple tags simultaneously. Each row in the CSV creates or updates one **Tag** under the selected Classification.
To import tags into a classification:
1. Navigate to **Govern** > **Classification**.
2. Select the classification you want to import tags into.
3. Click the **⋮** icon and select **Import**.
4. Drag and drop a file, or click **Browse** to upload your tags. Click **Download CSV Template** for a starter file, or **View Column References** for the full list of supported columns.
The template includes the following columns:
| Column | Required | Description |
| --------------------- | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **parent** | No | Leave blank to add the tag at the top level of the classification. |
| **name** | Yes | The name of the tag. Reuse an existing tag's name to update that tag. A different name produces a different fully qualified name, so it creates a **new** tag instead of renaming the original one. |
| **displayName** | No | The display name of the tag. |
| **description** | No | The description or details of the tag. |
| **reviewers** | No | Users who review and approve changes to the tag. |
| **owner** | No | The team or user who owns the tag. |
| **tagStatus** | No | The tag's approval status. |
| **color** | No | The color of the tag's icon. |
| **iconURL** | No | The icon shown for the tag. |
| **domains** | No | The domain(s) the tag belongs to. |
| **mutuallyExclusive** | No | Whether the tag is mutually exclusive with other tags in the same classification. |
Leaving `mutuallyExclusive`, `tagStatus`, `color`, or `iconURL` blank on an update keeps the tag's current value. Leaving `displayName`, `description`, `reviewers`, `owner`, or `domains` blank clears that field instead.
5. Click **Next: Preview**.
6. Preview and validate your uploaded data. Make any additions or corrections directly in the table if needed. A **Passed** and **Failed** count is displayed above the table to help you quickly identify any rows with validation errors before proceeding.
7. Click **Next** to import the tags.
System classifications (such as `PII` and `Tiers`) cannot be imported into or exported.
## Export a Classification
Download a classification's tags as a CSV file to share with your team:
1. Select the classification you want to export.
2. Click the **⋮** icon and select **Export**.
## Delete a Classification
Removing a classification permanently deletes its metadata:
1. Select the classification you want to remove.
2. Click the **⋮** icon and select **Delete**.
3. Click **Confirm** to delete the classification.
System classifications (such as `PII` and `Tiers`) cannot be deleted. Disable their tags or edit descriptions instead.
Add tags to data assets, or request them and discuss about the same, all within OpenMetadata.
