# Content Studio

> Author what a passport shows in Content Studio: section selection, field choices, alias deduplication, and the sync-on-publish draft tree model.

Content Studio is the authoring environment for passport content. It is where editors decide **what** appears on a passport, the sections, the field selection, and the prose that wraps regulated data.

## Concept Model

| Concept        | What it is                                                                                                   |
| -------------- | ------------------------------------------------------------------------------------------------------------ |
| **Section**    | A grouping of fields rendered as a single block on the passport (for example, *Materials*, *Origin*, *Care*) |
| **Field**      | A single piece of data, sourced from the product record, a custom field, or a market pack                    |
| **Block**      | A composable content unit: text, image, callout, disclosure                                                  |
| **Draft tree** | The unsaved working copy of the content: see [Editor State](#editor-state)                                   |

## Field-Alias Deduplication

When the same underlying field is reachable via more than one alias (for example, the deprecated `core.identity.brand_name` aliasing the canonical `core.identity.product_brand_name`), Content Studio deduplicates the field at edit time so the editor only ever sees a single, canonical entry. Deprecated aliases are read-only and surface a deprecation hint.

## Editor State

Content Studio uses a draft tree that is persisted as you work. Drafts are workspace-scoped, never published implicitly, and follow a strict **sync-on-publish** model, content is written into the live passport configuration only when the editor explicitly publishes.

## Sections Available

Available sections are derived from the brand's industry classification and the DPP Field Catalogue. Up to 15 sections can appear on a passport. Section order can be reordered within Content Studio.

## Relationship to Themes

Content Studio is concerned with **what** is presented. [Theme Studio](/authoring-studios/theme-studio) is concerned with **how** it is presented. The two surfaces are intentionally orthogonal: changing content does not change visual design and vice versa.
