## Description
OST AIO Smart Schema generates and outputs Google-recommended structured data (JSON-

editor sidebar — no manual coding required.

* Organization / LocalBusiness
* Product (with availability and condition)
* Event
* JobPosting
* VideoObject
* Course
* Review
* BreadcrumbList (automatic)
* ItemList (archive / search pages)
**Key Features**
* Outputs JSON-LD directly to `` via `wp_head`
* Gutenberg block editor sidebar integration — select schema type per post
* Global defaults configurable per post type from the settings page
* Organization / LocalBusiness settings with opening hours and price range
* XSS-safe output using `wp_json_encode` with JSON_HEX_* flags
* Automatic breadcrumb schema for hierarchical content
### External services
This plugin uses one third-party service, and only inside the wp-admin settings
screen (Settings OST). It is never loaded on the front end.
**YubinBango (Japanese postal-code address auto-completion)**
On the settings screen the plugin loads the YubinBango script from `https://yubinbango.
github.io/yubinbango/yubinbango.js`. It is used so that, when an administrator types
a Japanese postal code into the address fields, the matching prefecture / city /
town is filled in automatically.
* What data is sent and when: When (and only when) an administrator enters a postal
code on the settings screen, YubinBango requests the corresponding address-data
file from the YubinBango data service hosted on `yubinbango.github.io`. Only
the entered postal code is used for the lookup; no personal data, site data,
or credentials are transmitted.
* Service / source code: https://github.com/yubinbango/yubinbango (MIT License)
* The files are served from GitHub Pages, so the following policies apply:

### Source code and build
This plugin is not obfuscated. The compiled editor bundle `build/index.js` is generated
from the human-readable source in the `src/` directory, which is included in the
plugin package.
Build tools and steps (uses [@wordpress/scripts](https://www.npmjs.com/package/@wordpress/scripts)):
```
npm install
npm run build
```
The compiled output is written to the `build/` directory.
## Installation
1. Upload the `ost-aio-smart-schema` directory to the `/wp-content/plugins/` directory.
2. Activate the plugin through the **Plugins** menu in WordPress.
3. Go to **Settings > OST** to configure the organization name, logo, and other global
settings.
4. When editing a post or page, find the **OST Schema** panel in the editor sidebar
and select the appropriate schema type.
## FAQ
### Which post types are supported?
All public post types are supported. You can set a default schema type for each
post type in the plugin settings, and override it on a per-post basis from the editor
sidebar.
### Does this plugin conflict with other SEO plugins?
OST AIO Smart Schema outputs JSON-LD only. It does not modify meta tags or Open
Graph data, so it can be used alongside most SEO plugins (Yoast SEO, All in One
SEO, etc.).
### Where is the structured data output?
