# Data Glossary

> **Private preview:** The Data Glossary is currently in private preview. To enable this feature for your account, please contact support.

The Data Glossary lets you define and manage **business terminology** and definitions for your organization. Terms are organized by **domains**, so you can scope definitions to different parts of your data model (e.g., Sales, Finance, Marketing).

## What Is the Data Glossary?

A **glossary term** is a named business concept with:

* **Name** — The canonical term (e.g., "Customer", "ARR", "Churn")
* **Description** — What it means in your organization
* **Domain** — Which domain it belongs to (terms are scoped to domains)
* **Owner** — Who is responsible for the definition
* **Synonyms** — Alternative names (e.g., "Client" for "Customer")
* **Tags** — Labels for filtering and grouping

Glossary terms appear as resources in the data graph and can be used by the AI assistant and EQL to understand your organization's vocabulary.

## Creating a Term

1. Go to **Data Glossary** in the navigation.
2. Click **Add term**.
3. Fill in:
   * **Name** — Required, unique within the domain
   * **Domain** — Select the domain (create domains in Account Settings → Domains first)
   * **Description** — Required
   * **Owner** — Defaults to you if left empty
   * **Synonyms** — Optional list of alternative names
   * **Tags** — Optional labels
4. Click **Create**.

You must have at least one domain before creating terms. Create domains in **Account Settings → Domains**.

***

## Editing and Deleting Terms

* **Edit** — Click the menu (⋮) on a term and choose **Edit**. Update any field and save.
* **Delete** — Click the menu and choose **Delete**. Confirm to remove the term.

When editing, you can move a term to a different domain. The name and synonyms must remain unique within the new domain.

***

## Searching and Filtering

* **Search** — Type in the search box to match term names or synonyms (case-insensitive).
* **Domain filter** — Filter by one or more domains.
* **Owner filter** — Filter by owner.
* **Tags filter** — Filter by tags (AND logic: term must have all selected tags).
