# Glossary

> Core concepts and terminology used in Gloo AI Studio.

***

## Organization

An **Organization** (often shortened to "Org") is the root entity in Gloo AI's multi-tenant architecture. All data, content, and users are scoped to a specific Organization. Every account belongs to at least one Org, and data is fully isolated between Organizations.

***

## Publisher

A **Publisher** is a sub-entity within an Organization that owns and produces content. All ingested content is associated with a Publisher. An Organization can have multiple Publishers, each representing a distinct brand, team, author, or imprint.

You must create at least one Publisher before uploading content. See [Manage Publishers](/studio/manage-publishers).

***

## Tenant

**Tenant** is an alias for Publisher used within the Data Engine context. When the API or Studio UI refers to a tenant, it means the Publisher that owns the content being operated on.

***

## publisher\_id

The **`publisher_id`** is the unique identifier for a Publisher, assigned by Gloo AI when the Publisher is created. It is required as a parameter in most Content API calls to scope operations to the correct Publisher.

You can find your `publisher_id` in Studio under **Manage Organizations → View Publishers**.

***

## item\_id

The **`item_id`** is Gloo AI's internal UUID assigned to each content item upon ingestion. It uniquely identifies an item across all API operations (edit, inspect, delete).

***

## producer\_id

The **`producer_id`** is your own internal identifier for a content item, optionally provided at upload time. It lets you reference items using your existing IDs without storing Gloo's `item_id`.

If you provide a `producer_id` at upload, you can use it to look up the corresponding `item_id` later via the [Get Item by Producer ID](/api-reference/content-controls/get-item-by-producer-id) endpoint.

## User Roles

Users in Gloo AI are assigned roles that determine what they can access within an Organization.

| Role       | Permissions                                                                               |
| ---------- | ----------------------------------------------------------------------------------------- |
| **Admin**  | Invite users, create and manage Publishers, manage content ingestion, view all analytics. |
| **Editor** | Upload content via Studio or API.                                                         |
| **Viewer** | View ingestion analytics and use components.                                              |

## Author

An **Author** is a user who creates content for one or more Publishers. A user becomes an Author only when invited by a Publisher and after accepting the invitation. Authors are distinct from Org-level roles — a user can hold both simultaneously.
