# Classifier

Available in VPC

 

A classifier provides classification features to determine schema when scanning unstructured data. Even without a classifier configured, the scanner automatically infers schema for files such as CSV, JSON, and XML. However, with a classifier configured, you can infer data in a specified format for files without a defined format, or generate metadata using only specific data. In the **Classifier** menu, you can create and manage classifiers.

## Create a classifier

To create a classifier:

1. In the VPC environment on the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Big Data & Analytics** > **Data Catalog**.
2. Navigate to **Configuration > Classifier**.
3. Click **[Create classifier]**.
4. In the **Create classifier** popup, enter the classifier information.
  - **Name**: Classifier name
  - **Type**: Data file format
  - Parsing settings: Enter the parsing settings based on the data file format.
    - **CSV**: Select a delimiter to separate data columns.
    - **JSON**: Specify a path to generate metadata only from the specified data.
      - Specify the store field (e.g., `$.store.`).
      - Specifies the author field under the book field within the store field (e.g., `$.store.book[*].author`).
    - **XML**: Specify a row tag to generate metadata only from the specified node data.
5. Click **[Create]**.

## Search classifiers and view information

To search classifiers you created and view information:

1. In the VPC environment on the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Big Data & Analytics** > **Data Catalog**.
2. Navigate to **Configuration > Classifier**.
3. In the search bar, enter the classifier name and click ![i-datacatalog-search](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/i-datacatalog-search.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A05%3A12Z&se=2026-11-14T06%3A05%3A12Z&sr=c&sp=r&sig=aU%2Fbt2PQT%2FUu3ngtqxAhOFfZ%2FsKpv9p04IDxHCBM2GI%3D) to search for the classifier and view its information.
  - **Type**: Data file format
  - **Name**: Classifier name
  - **Details**: Parsing settings specified during classifier creation
  - **Creation date and time**: Classifier creation date and time
  - **Update date and time**: Date and time when the classifier is last modified

## Edit classifiers

To edit the information of classifiers you created:

1. In the VPC environment on the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Big Data & Analytics** > **Data Catalog**.
2. Navigate to **Configuration > Classifier**.
3. Click the classifier you want to edit, and then click **[Edit]**.
4. In the **Edit classifier** popup, edit the classifier information.
  - For more information on each item, see [Create classifier](/docs/en/datacatalog-classifier-vpc#%EB%B6%84%EB%A5%98%EC%9E%90%EC%83%9D%EC%84%B1).
5. Click **[Edit]**.

## Delete a classifier

To delete a classifier you created:

              Caution

              

- If you delete a classifier, scanners connected to it might not work correctly.
- A deleted classifier cannot be recovered.

1. In the VPC environment on the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Big Data & Analytics** > **Data Catalog**.
2. Navigate to **Configuration > Classifier**.
3. Click the classifier you want to delete, and then click **[Delete]**.
4. When the **notification** popup window appears, read the cautions and click **[Delete]**.
