# Viewing and Editing Data Source Information

## Viewing Data Source Information

To view a data source's (DS) information, open the contextual menu associated with the DS, then select **Display Information**.

The interface that opens is composed of one to four tabs, depending on the type of data in the source:

* **Information**: present in all DS, this tab contains general information and a data preview.
* **Attributes**: vector and non-spatial tabular DS have attributes (or fields) whose details are presented in this tab.
* **Relationships**: this tab allows you to configure relationships between vector and non-spatial tabular DS. Relationships can be established between two vector DS, between two non-spatial tabular DS, or between a vector DS and a non-spatial tabular DS. You can see this tab if you have permission to modify the data source.
* **Metadata**: this tab allows you to configure metadata that will be displayed in the layers of projects published via JMap NG.

## Editing Parameters

If you have modification permissions on the DS, you can modify certain parameters directly from the interface:

* By hovering over the **Description**, **Tags**, or **Unique Identifier** (for spatial DS) fields, the text box becomes active and you can modify the content.
* You can also modify:
  * The **title** of attributes
  * Their **indexing status**
  * And **create, modify, or delete** a value domain (for text or numeric type attributes)

Click ✓ to save or ✗ to cancel the changes.

{% hint style="info" %}
Only indexed attributes can be used in simple searches in the JMap NG mapping application (searching for features based on attribute values).
{% endhint %}
