# Meta Information
|
|
|
|
You can add meta information at various levels of the document using the `meta` method.
|
|
|
|
## Document Meta
|
|
|
|
To add meta information at the top-level of a document, you can call the `meta` method on the `Context` instance which is available inside any of your schema's callbacks.
|
|
|
|
For example, to add meta information to a resource listing, you might call this inside of an `onListed` listener:
|
|
|
|
```php
|
|
$type->onListed(function ($models, Context $context) {
|
|
$context->meta('foo', 'bar');
|
|
});
|
|
```
|
|
|
|
## Resource Meta
|
|
|
|
To add meta information at the resource-level, call `meta` on the schema builder.
|
|
|
|
```php
|
|
$type->meta('updatedAt', function ($model, Context $context) {
|
|
return $model->updated_at;
|
|
});
|
|
```
|
|
|
|
## Relationship Meta
|
|
|
|
Meta information can also be [added to relationships](relationships.md#meta-information).
