# Federated Index

## Purpose

Federated Index Vocabulary manages named vocabulary terms.

Use it to keep controlled terms that can support structured indexing or search.

## What You Can Do Here

- Federated Index Vocabulary manages named vocabulary terms.
- Edit or inspect the specific content object shown on the page.
- Check whether the result is local-only, user-visible, or peer-visible before publishing.

## Page Architecture

Content application pages store and render peer-local objects such as bookmarks, messages, tables, profiles, or translations. They combine form editing with a rendered view of the stored object.

| Control | Meaning | Values or examples |
| --- | --- | --- |
| `vocabulary` | Vocabulary Name / Objectspace. | Text value; use the page label and surrounding context to choose the exact content. |
| `view` | Vocabulary Name. | `View` |

## Correct Use

Edit content deliberately and check the rendered page after saving. For shared or peer-visible features, assume written content may be read by someone else unless the page clearly says otherwise.

## Access And Safety

Administrator access is required. YaCy protects `_p` pages as administration pages.

Protected related endpoint(s): `/Vocabulary_p.html`.

Backend checks: transaction token for protected POST, transaction token issued for forms.

## Automation And API

Page backend: `source/net/yacy/htroot/Vocabulary_p.java`.

| Endpoint | Method | Access | Backend |
| --- | --- | --- | --- |
| `/Vocabulary_p.html` | `GET` | admin | `source/net/yacy/htroot/Vocabulary_p.java` |

## What To Expect

Expect stored or rendered content: a message, page, table row, bookmark, profile, translation, or file view. After changes, reload or revisit the object to confirm what was actually saved.
