# Manage metadata
|
|
|
|
Manage metadata for your dataset and for your individual documents.

From v0.23.0 onwards, RAGFlow allows you to manage metadata both at the dataset level and for individual files.
|
|
|
|
|
|
## Procedure
|
|
|
|
1. Click on **Metadata** within your dataset to access the **Manage Metadata** page.
|
|
|
|
|
|
|
|
|
|
2. On the **Manage Metadata** page, you can do either of the following:
|
|
- Edit Values: You can modify existing values. If you rename two values to be identical, they will be automatically merged.
|
|
- Delete: You can delete specific values or entire fields. These changes will apply to all associated files.
|
|
|
|
_The configuration page for rules on automatically generating metadata appears._
|
|
|
|
|
|
|
|
3. To manage metadata for a single file, navigate to the file's details page as shown below. Click on the parsing method (e.g., **General**), then select **Set Metadata** to view or edit the file's metadata. Here, you can add, delete, or modify metadata fields for this specific file. Any edits made here will be reflected in the global statistics on the main Metadata management page for the knowledge base.
|
|
|
|
|
|
|
|
|
|
4. The filtering function operates at two levels: knowledge base management and retrieval. Within the dataset, click the Filter button to view the number of files associated with each value under existing metadata fields. By selecting specific values, you can display all linked files.
|
|
|
|
|
|
|
|
5. Metadata filtering is also supported during the retrieval stage. In Chat, for example, you can set metadata filtering rules after configuring a knowledge base:
|
|
|
|
|
|
|
|
- **Automatic** Mode: The system automatically filters documents based on the user's query and the existing metadata in the knowledge base.
|
|
- **Semi-automatic** Mode: Users first define the filtering scope at the field level (e.g., for **Author**), and then the system automatically filters within that preset range.
|
|
- **Manual** Mode: Users manually set precise, value-specific filter conditions, supported by operators such as **Equals**, **Not equals**, **In**, **Not in**, and more.
