# Knowledge Loader

## Purpose

Knowledge Loader imports word lists or dictionaries.

Use it when vocabulary data should support search, classification, or local knowledge features.

## What You Can Do Here

- Knowledge Loader imports word lists or dictionaries.
- 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, wiki text, tables, profiles, or translations. They combine form editing with a rendered view of the stored object.

## 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): `/DictionaryLoader_p.html`.

## Automation And API

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

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